Nomenclature and Typification of the Jasione L. (Campanulaceae) Groups from the Eastern Mediterranean Basin

In this research, all the published names of Jasione (Campanulaceae) in the species, subspecies, and variety ranks for populations from the Balkan and Anatolian peninsulas are reviewed, including names of taxa allied to these groups in surrounding areas. These two areas are among the main centers of diversity of the genus, albeit no recent revisions to address the regional taxonomical complexity of the genus have been published for the Balkans and Anatolia. In this work, the taxonomic status and typification of twenty-six published names are discussed, including the plethora of names within the Jasione heldreichii, J. supina, and J. orbiculata taxonomic complexes. In total, eleven lectotypes and one neotype are designated for names from the aforementioned regions, plus one from southern Italy. This nomenclatural clarification establishes a reference for ongoing and future taxonomic and evolutionary studies of Jasione in the Mediterranean basin. In a genus prone to micro-endemism and cryptospeciation, a number of the historically described forms, despite being disregarded by current taxonomic treatments, may, therefore, deserve further attention.


Introduction
The genus Jasione L. (Campanulaceae) is distributed around the Mediterranean basin and throughout Europe, with two centers of diversity at the opposite sides of the Mediterranean Sea, one in the Iberian Peninsula and Morocco and another in the Balkan and Anatolian peninsulas, consistent with the West-East Mediterranean disjunction biogeographical pattern [1,2].The genus occurs in a number of ecological conditions and geological substrates across a wide elevational range, including coastal and alpine habitats.The combination of environmental niche diversity, complex geological history of the Mediterranean basin and ploidy variation, which includes five ploidy levels [3,4], own data, coupled with relative stasis around a general morphological pattern (i.e., medium-sized or small plants with condensed inflorescences in flower heads surrounded by involucral bracts and small flowers with connate anthers), has produced a large number of polymorphic populations frequently lacking clear morphological distinctiveness.In consequence, many names and different taxonomic ranks have been used for members of the genus (e.g., [4][5][6]).However, most of these names are of unknown evolutionary significance [7], leading to difficulties in species delimitation by morphological approaches [8].General treatments of the genus thus tend to be overly summarized, with the number of species recognized varying between twelve [9] and seventeen [10].The evolutionary lineage of Jasione seems to be prone to micro-endemism and cryptospeciation, and many of the historically described forms, despite being disregarded by current taxonomic treatments, may, therefore, deserve further attention.Thus, a correct nomenclatural understanding of the clutter of names described so far is particularly important in studies dealing with evolutionary relationships, species delimitation, and biodiversity conservation in such complex groups.
Plants 2024, 13, 50 2 of 22 Two important nomenclatural summaries have been provided for the center of diversity of Jasione in areas of the western Mediterranean region.Dobignard and Chatelain [6] reviewed the synonym names published for North African populations, while Sales and Hedge [5] tackled the revision of the published names and nomenclatural types of the taxa occurring in the Iberian Peninsula.Parnell [11] had previously addressed the nomenclature of Jasione montana L. and other taxa that he considered related, dealing with a huge number of published names associated with the wide range and considerable polymorphism of J. montana, which occurs in northwestern Africa and most of Europe (although it is almost absent in the Balkan area).These works were later complemented by nomenclatural precisions in the Iberian-North African Jasione corymbosa poir.ex Schult complex [12].
By contrast, there are no recently published revisions for the eastern center of diversity of the genus.The most recent comprehensive work dealing with Jasione in the Balkan and Anatolian peninsulas is that of 1926 by Stojanov [13], with a taxonomic treatment recognizing thirteen species and varieties, one from the Italian peninsula.This author addressed the alpine taxa of what he called the Jasione supina Sieb.ex Spreng.group, a number of mostly narrow endemic orophytes occurring across different mountain ranges in both peninsulas.This group would include the Jasione supina complex, the Jasione orbiculata Griseb.ex Velen.complex, and Jasione bulgarica Stoj.and Stef.Nevertheless, the evolutionary coherence of this putative group and its internal relationships remain unknown.Stojanov [13] did not consider the Jasione heldreichii Boiss.and Orph.complex, the other remaining group occurring in the Balkan and Anatolian peninsulas.Parnell [11] only partly addressed the nomenclature of this complex, describing one variety occurring on the Turkish coasts.A wider study is required that would encompass the nomenclature of the group, within which diverse names with difficult taxonomic interpretation have been described [14].
Tutin [15] subordinated J. orbiculata as a subspecies of Jasione laevis Lam. in his treatment previous to Flora Europaea [16].This rather questionable view overshadowed all taxa described or recognized by Stojanov [13] within this species, probably influencing later general treatments that only listed J. orbiculata [4,10,17].The fact that these taxa have the rank of variety has also hampered their modern recognition, although some of them have been included in regional floras (e.g., J. orbiculata subsp.balcanica Urum. in [18]).
Damboldt [19,20] tackled the taxonomic diversity of the Anatolian Jasione orophytes, recognizing two species in this group, i.e., J. idaea Stoj.and J. supina, the latter of which has four subspecies.He designated nomenclatural types to several names in the Flora of Turkey and the East Aegean Islands [20], although a formal typification of some of them is still lacking.
The research presented here aims to present a nomenclatural revision of the genus Jasione in the Balkan and Anatolian peninsulas, the eastern center of diversity of the genus, and complements the current studies of the authors on taxonomy and evolutionary relationships in the genus Jasione.The nomenclatural situation of the Balkan and Anatolian taxa of Jasione, including the J. heldreichii, J. supina, and J. orbiculata taxonomic complexes, are addressed by summarizing synonyms and designating types.The application of the many names described from the aforementioned regions, plus one from southern Italy, is discussed.

Materials and Methods
Currently accepted names, including homotypic and heterotypic synonyms, those listed in the Med-Checklist [17], the World Checklist and bibliography of the Campanulaceae [4] and the Euro+Med Plantbase [10] were considered.Other names were obtained from diverse sources (see below), mainly Stojanov [13] and Damboldt [20].The protologues and original material of names were analyzed in detail, and those names lacking a nomenclatural type were typified in accordance with the International Code of Nomenclature for algae, fungi, and plants [21].The following herbaria were consulted: B, BR, E, G, FI, K, MPU, P, SO, SOM, GOET, and W. Most of these herbaria conserve the relevant material for the typification of Jasione from the studied regions; others are the herbaria of reference of a botanist that worked on Jasione in Anatolia and/or the Balkans.The herbaria were consulted in person (as is the case of K and SOM) or digitally, accessed via the JSTOR Global Plants platform, or online virtual herbaria.Herbaria curators were also requested for digitally scanned images from their collections.

Results and Discussion
3.1.Nomenclature and Typification of the Jasione Complexes from the Eastern Mediteranean Basin All names described for Jasione in the Balkan and Anatolian peninsulas at the species, subspecies, and variety ranks were analyzed.Thus, the members of the J. orbiculata complex were included, and the representative of the complex in southern Italy is therefore also treated here.The review presents basionyms in alphabetical order, structured as a discussion of each name followed by its synonyms and typification, designating types when required.A list of currently accepted names from relatively recent checklists (e.g., [4]) is provided, and the heterotypic synonyms are indicated (Table 1).The inclusion of a name in the first column of Table 1 only reflects its situation in current general lists, as recognized names may be organized differently after ongoing phylogenetic studies on Jasione.Notwithstanding, as a prelude to a more formal taxonomic treatment informed by phylogenetic relationships, Table 1 underlines those names that, in the opinion of the current authors, would merit taxonomic recognition, irrespective of whether future systematic works may propose new combinations of their taxonomic rank.
Table 1.Names currently accepted in general treatments (e.g., [4]) are ordered alphabetically in the first column and marked in bold, with basionyms indicated.The second column lists their heterotypic synonyms following current general treatments.Names underlined are those that, in our view, merit taxonomic recognition at the current state of knowledge of ongoing phylogenetic studies and should be accepted.

Jasione bulgarica
Stojanov and Stefanov [22] used material from the Rila mountain range to describe this name, indicating in the protologue a flowering period of July to September 1919 in Rila, but without citing any particular specimen in relation to the name.The protologue includes two illustrations, a photograph with six separated plants (protologue, Image 2 on page 106) that matches several aspects of the description, i.e., glabrous plants with upright stems and creeping roots, and a drawing (protologue, Image 3 on page 107) of a flower showing the character considered most remarkable by the authors, i.e., the free anthers (contrasting with the connate anthers in the remaining species of the genus).The current authors have no evidence of a formal description of the type, and one of the illustrations could, therefore, be selected to designate a lectotype, according to articles 8.1 and 9.12 of the International Code of Nomenclature.Given the importance the name's authors attributed to the character of the free anthers, the second illustration (protologue, Image 3 on page 107) should be preferred for this purpose.However, several sheets of the material collected by Stojanov and Stefanov in the Rila mountains in July and September 1919 are conserved in herbarium SOM (e.g., SOM 75792, SOM 75780, SOM 75789, among others).It therefore seems reasonable to assume that these authors used at least some of this material to prepare the description, although they did not cite any of these gatherings in the publication.Given that the authors refer to both July and September 1919 in the protologue only as an indication of the flowering phenology in Rila and not as specimen collections, no particular collection can be unambiguously associated with the illustrations.After careful analysis of the sheets in SOM, the current authors could not match any of these specimens to the flowering stems photographed in the first illustration of the protologue.Stojanov and Stefanov [22] stated that they had seen sheets of the new species in the herbaria of V. Stříbrný and I. Urumov, labeled as, and sometimes mixed with, J. orbiculata.However, they did not cite any particular gathering that could be chosen as the lectotype.Although none of the specimens conserved in SOM has been explicitly associated with the taxon in [22], they were most probably among the materials used to describe the species as they were collected at the locus classicus in a month (July) indicated in the protologue, and as available specimens according to article 9.4 of the International Code of Nomenclature these specimens could be considered original material.Therefore, and also because a physical specimen will always have more characters than an illustration, the current authors have selected as lectotype the specimen SOM75792!Collected by Boris Stefanoff on 25th July 1919 in Malyovitsa (Мaльовицa) in the Rila mountain range (Figure 1).
The designated lectotype is, logically, also the type of Jasionella bulgarica (Stoj.and Stef.)Stoj and Stef., and it is consequently the species' type of Jasionella Stoj.and Stef (1933), a monotypic genus described on the basis of the free anthers in the flower as the main trait differentiating the genus from Jasione L.

Jasione glabra
Velenovský [23] described this species from material collected in the vicinity of Varna, on the Black Sea coast in Bulgaria, sent to him by A. Javasof.The lectotype is held in PRC (PRC 451934), and it matches the protologue description of a glabrous plant without basal leaves, somewhat undulate stem leaves, and bract teeth and apex apparently not ending in hard awns.This plant can be included in the variability of J. heldreichii Boiss and Orph., as considered by Velenovský [24], who later lowered its rank by describing it as J. heldreichii var.microcephala.This author (op.cit.) also wrote that this name alluded to the same plant that he had described under the name J. glabra, adding a shorter morphological description, but similar to that included in the protologue of J. glabra, giving Varna, Bulgaria as the type locality.According to Art. 6.12 of the International Code, J. heldreichii var.microcephala Velen. is validated as a replacement name for J. glabra Velen., as it is only validated by reference to the earlier name.Thus, it is automatically typified by the type of J. glabra.The lectotype was designated by Ančev [18].

Jasione heldreichii
The lectotype [11] shows an annual-biennial habit and bracts with aristate teeth, matching the description in the protologue [25] and the narrower concept used by diverse authors whereby J. heldreichii is only considered to be annual-biennial.Two main morphoecological patterns can be found within the J. heldreichii complex populations (without taking into account some deviant maritime forms): one of annual-biennial hairy plants without sterile rosettes, mostly occurring at mid-low elevations and another of perennial glabrescent plants with sterile rosettes and occurring at higher elevations or northern latitudes [14].Some authors avoid using the name J. heldreichii for the latter forms, preferring either J. jankae Neilr.(e.g., [14,26,27]) or J. dentata (DC) Halácsy sensu Josifović [28] non sensu orig.for these populations.Nevertheless, current treatments synonymize J. jankae under J. heldreichii, encompassing both annual-biennial and perennial plants [4,[16][17][18]20].Parnell [11] designated the lectotype of this name by indicating "Macedonia, 1857, Orph.Lectotype: G!" Unaware of this, Hartvig [14] apparently used material from the same collection to designate a lectotype, indicating "Macedonia, Mt.Korthiathi prope Thessalonicam, Orphanides 663 (G-Boiss!)".Examination of the type material in G clearly shows that the lectotype designated by Parnell [11] belongs to a different collection (Orphanides n• 3130) than that used by Hartvig [14].The former has the G barcode G60078161.Regarding the variability in J. heldreichii, the current authors were able to observe in the type locality that some rare individuals can develop a few sterile rosettes.Indeed, there are some intermediate populations in regard to this trait (own data, personal observations of Miguel Serrano in Greece and Bulgaria), and populations with some individuals developing sterile rosettes and others without them have been recorded after cultivation of the plants and monitoring of their development [29].

Jasione heldreichii var. Papillosa
Parnell [11] used this name to encompass some morphologically deviant populations of group J. heldreichii occurring on the Turkish European coast of the Black Sea.These plants are characterized by densely papillose bracts and leaves with thickened margins, and short-triangular calyx teeth.The holotype, held in herbarium E, originates from the T. Uslu n• 2070 collection from Istanbul, Terkos Gölü.The specimen has the E barcode E00913661.Although these populations may simply be coastal ecotypes of J. heldreichii, the evolutionary significance must be studied in greater detail as they display some different traits from other dune populations of J. heldreichii from the Aegean and Black seas.J. heldreichii var.papillosa is remarkably distinct from the typical J. heldreichii, showing morphological convergence with populations of J. montaçelena from sand dune habitats in the western Mediterranean region under similar climatic conditions (i.e., subhumid Mediterranean climate).Indeed, this is the reason for the inclusion of J. montana in the Flora of Turkey and the East Aegean Islands [20], an enduring incorrect interpretation of these populations (e.g., [30]).

Jasione idaea
This name was published by Stojanov [13] to describe a narrow endemic species in the Kazda gı, the ancient Mount Ida, in northwestern Anatolia, using one collection of Sintenis (Iter trojanum, 1 Aug. 1993, n• 532).Damboldt [20] addressed the typification of this name from this collection.However, he designated a holotype by indicating "holo.W! iso.B, M, E!, G! GOET, K! LD".Many specimens exist from the original collection, and the lectotype should be designated in accordance with article X.X of the International Code.Therefore, the current authors designated one of the many specimens from the original collection as the lectotype, the sheet in herbarium E with barcode E00913653, which is shown in Figure 2.

Jasione jankae
This name is listed as a synonym of J. heldreichii Orph.ex Boiss. in Flora Europaea [16], the Med-Checklist [17], and in the World Checklist of the Campanulaceae [4], although it is recognized in the Euro+Med PlantBase [10], as well as in different regional floras from the Balkan Peninsula (e.g., [14,24,26]), while other floras consider it a synonym of J. heldreichii (e.g., [18,[31][32][33]).Neilreich [34] described this species from material collected in the rocky areas of Treskovac, NW of Svinica, in Romania (current names in Romanian language, Trescovăţ and Sviniţa).In herbarium C (C barcode C10009017) there is a gathering collected by Viktor Janka in "rupestribus m.Treszkovácz inter Drenkova et Svinieza ad Danubium inferioren Banatus", on 4 July 1870 during his Iter Banaticum.The specimen is identified in the sheet as J. jankae Neilr.and two manuscript labels dated September 2004 are glued on it (Figure 3).One label, by I.C.Hedge, indicates that "the formal lectotypification of J. jankae will be published in due course", and the other, by S. Prince, indicates "Lectotype of Jasione jankae Neil.= J. heldreichii Boiss & Orph."The current authors have no evidence of any subsequent formal publication and, therefore, have designated this specimen as the lectotype.There is no doubt that this material was used by Neilreich to describe the species, as correctly pointed out by I.C.Hedge and S. Prince, as the label clearly conveys the location cited in the protologue, and the specimen matches all points in Neilreich's description.

Jasione montana var. Dentata
De Candolle [35] described this name from plants collected by P.M.R. Aucher-Eloy in the "Olympo Bithino", i.e., in the UluDag, Turkey.The G-De Candolle herbarium (GDC) holds a gathering collected by Aucher-Eloy from the type location in 1837, number 1880 (G barcode G00329536), matching the morphology described in the protologue (i.e., spiny-dentate acute bracts) shown here in Figure 4.The current authors are not aware of  The status of J. jankae in relation to J. heldreichii has been controversial, even in some of the treatments that recognize it as different from J. heldreichii [14].Ciocârlan [27] addressed the question by adopting the position of differentiated species but provided little more evidence than the differing morphological features already described in the protologue.Thus, J. jankae may refer to plants similar to J. heldreichii but differing in the perennial habit with sterile rosettes, rather than to annual-biennial habit without rosettes in J. heldreichii, dentate bracts but with teeth half the width of the bract teeth rather than pinnate-pectinate bracts with aristate apex.However, as intermediate individuals are found, a wider concept of J. heldreichii, including plants from mountain or northern areas where sterile rosettes are more frequent, may appear to be more consistent with the current state of knowledge.Nevertheless, more detailed studies are needed to ascertain whether the observed variation can be linked to independent evolutionary lines.Different degrees of introgression in J. heldreichii populations from current or past sympatric populations of representatives of the J. orbiculata and J. supina perennial groups should not be ruled out as a source of morphological and ecological differentiation within the J. heldreichii complex.

De Candolle [35] described this name from plants collected by P.M.R. Aucher-Eloy in the "Olympo Bithino", i.e., in the UluDag, Turkey.The G-De Candolle herbarium (GDC) holds a gathering collected by Aucher-Eloy from the type location in 1837, number 1880 (G barcode G00329536), matching the morphology described in the protologue (i.e., spinydentate acute bracts) shown here in Figure 4.The current authors are not aware of any formal description of the type of this name and have, therefore, designated this specimen as the lectotype.Another sheet from the Aucher-Eloy n• 1880 collection in K (K barcode K000781177) would be an isolectotype.The name and the more frequently recognized Halacsy's combination [36] is Jasione dentata (DC.)Halacsy has been used for plants from Anatolia and from the Balkan Peninsula (e.g., [28,36]).Although the most commonly followed current treatments consider this name a synonym of J. heldreichii [16,18], more detailed evolutionary studies are required to clarify this point, given the complexity of the group.

Jasione orbiculata
This name has been generally recognized at the species rank [4,17,18], despite its treatment in Flora Europaea subordinated as a subspecies of J. laevis Lam.[16], which has influenced some subsequent works [14,37].Grisebach [38] created this name in the entry for J. supina Sieb. in his Spicilegium florae Rumelicae et Bithynicae, although without indicating the morphological features that characterize it and differentiate it from J. supina, and without associating this name with any particular location.In the entry he cited several Balkan and Anatolian regions and localities (Macedoniae, Bithyniae, Kobelitza, Peristeri, Olympo in Turkey) but without connecting the new name to any of them.Velenovský [24] validly described the species, separating the Balkan plant from J. supina, recognizing the authorship by Grisebach and explicitly referring to the name proposed in the Spicilegium.Velenovský himself [24] did not see the original Balkan material from Peristeri and Kobelitza cited by Grisebach [38].Stojanov [13] also did not cite this material despite carrying out a huge revision of specimens of the group in different European herbaria.Strid [39] found, in this author's words, a "rather fragmentary specimen" at G-BOIS, labeled "Jasione orbiculata Gr.Scardus.Turquie d'Europe.Grisebach 1842", which was designated as a lectotype.Scardus refers to the Šar Mountains, the mountain range to which Kobelica [Kobelitza] peak belongs.1842 is presumably the year the specimen was received in Geneva, as it is known that Grisebach collected in Kobelica mountain on 21 July 1839 [39].Despite having consulted diverse herbaria, including GOET -the herbarium of reference of Grisebach [40]it was not possible to locate any other material collected by Grisebach that could be related to this taxon.
Plants 2024, 13, x FOR PEER REVIEW 10 of 24 followed current treatments consider this name a synonym of J. heldreichii [16,18], more detailed evolutionary studies are required to clarify this point, given the complexity of the group.

Jasione orbiculata var. Balcanica
This name has been considered by Lammers [4] as a synonym of J. orbiculata s. str.and is not listed in general treatments (e.g., [10,17]), although it has been recognized by Ančev [18].Urumov [41] described this name, indicating two localities and a year "In graminosis alpinis m.Jumruk-Cal, Mara-Gidik legit a. 1897", with the former location being in the Rila Mountain range and the latter in the Central Balkan Mountain range.The current authors have found a gathering collected by Urumov in 1897 in Jumruk-Cal in the SOM herbarium (SOM75664) that matches the description in the protologue, i.e., leafed ascendent stems, undulate-denticulate obtuse leaves, wide, and obovate bracts overpassing the flowers and subsessile flowers (Figure 5).The current authors have not found any evidence of formal typification of this name and have, therefore, designated this specimen as the lectotype.

Jasione orbiculata var. Bosniaca
Like all the varieties of J. orbiculata described by Stojanov [13], this is listed as a synonym of J. orbiculata s. str.By Lammers [4].Although this plant exhibits a markedly different morphology from the typical J. orbiculata, the use of this name is virtually absent in the regional botanical literature [42][43][44].Stojanov [13] used diverse collections from a wide range to describe this name, including gatherings from NW Macedonia, Albania, Montenegro, and Bosnia-Hercegovina.Among the diverse materials he cited in the protologue, there is one gathering collected by E. Brandis in Bosnia from Vranika Sekira peak, 15 July 1892.There is one specimen (MPU barcode MPU016152) from this gathering in MPU.The sheet has a glued label, dated 2010 by P.R. Fabre, indicating "isosyntype of J. orbiculata var.bosniaca" (Figure 6).The current authors have no evidence of a formal typification of

Jasione orbiculata var. Italica
This name is considered a synonym of J. orbiculata s. str.by Lammers [4] and is not included in the Checklist of the Italian vascular flora [46] or used in recent works addressing the conservation status of its populations [47], although it is recognized in Pignattti's Italian floras [48,49].This name refers to a narrow endemic restricted to the Sirino Massif, Basilicata, southern Italy [50].Stojanov [13] cited it in three gatherings included in the protologue, one from "Montis Serino del Papa", 14 July 1877 collected by Huter, Porta, and Rigo, another from "Monte Serino, pr.Lago Negro", July 1877 collected by Huter, and another from "M.Serino" July 1898 collected by G.

This name is considered a synonym of J. orbiculata s. str.by Lammers [4] and is not recognized in regional floras or taxonomic lists [14,51].Stojanov [13] described the name from material collected in the Kaimaktsalan massif, on the border between North Macedonia and Greece, and from Smolikas peak in the Pindos Mountain range in Epirus, Greece.However, as noted by Hartvig [14], there is significant variation among the Greek populations, with mat-forming plants with creeping, rooting stems and ovate-rhomboidal bracts in the SW populations and more cespitose plants with narrower lanceolate-linear bracts in the northernmost Greek populations.While the epithet "supinoides" (i.e., resembling J. supina Sieb., a cespitose plant) would be suitable for populations from the mountains on the border between North Macedonia and Greece, the description in the protologue could encompass all of these Greek forms.However, the mention of oblongo-rhomboidea bracts is more consistent with the plants from the Pindus Mountain range.The current authors have located two sheets in herbarium P (P barcodes P00270608 and P00270609) of a collection of Antonio Baldacci from Smolikas, one of the three gatherings cited by Stojanov in the protologue.The current authors have not found any evidence of previous typification of this name and have, therefore, designated one of these sheets as the lectotype (Figure 8).

Jasione orbiculata var. Orbelica
Velenovský [52] described this name in supplementum I of Flora Bulgarica.In this work, he tackled the morphological description of two varieties of J. orbiculata Griseb., conveying doubts about which was Grisebach's plant.He left the first variety unnamed, supposedly because he found it was more similar to the typical J. orbiculata, although this is not certain.Secondly, the var.orbelica was described as a plant with longer, thicker, and straight stems, larger denticulate leaves and glabrous acutely denticulate bracts.Stojanov and Stefanov [22] and Stojanov [13] noted that the morphological description of this name matched J. bulgarica.However, as Velenovský [52] said nothing about one of the main features of J. bulgarica, i.e., the free anthers, the description could also match some forms of J. orbiculata.Stojanov [13] thought that this was the reason for Velenovský's doubts about which of the two varieties that he morphologically described would correspond to Grisebach's J. orbiculata.Nevertheless, the forms of J. orbiculata that could match Vele- sence of any evidence of previous formal typification of the variety, the current authors have designated Reiser's sheet annotated by Velenovský as the lectotype (Figure 9).In any case, this name is a synonym of J. bulgarica.

Jasione supina
This name was published by Sprengel [53], who recognized Sieber as the author's name and vaguely indicated "Asia minor?" as the type locality.Damboldt [19] revised the names of the J. supina group, adopting De Candolle's [35] concept of the species for use in the Flora of Turkey and the East Aegean Islands [20].This interpretation of J. supina is based on the population collected by Aucher (n• 1881) in 1837 from the "Bithynian Olympus", i.e., the Uluda g mountain in Bursa province, Turkey.Neither Damboldt nor the current authors have located any original material collected by Sieber, although it may exist somewhere.Damboldt [20] addressed the typification of this name with Aucher's n• 1881 gathering, indicating "Neotype: Turkey, Bursa, Olympus Bithynus (Ulu Da.), 1837, Aucher 1881 G! W!)". Given that two sheets in different herbaria were designated as neotypes, there is some ambiguity regarding the actual type.Therefore, according to the International Code (Art.9.17), as a second-step typification [21,54], the current authors have designated the sheet in G (G barcode G00329587) as neotype (Figure 10).

Jasione supina subsp. Akmanii
This name and rank are recognized by Greuter et al. [17] and Lammers [4], although the close affinity to J. supina subsp.pontica (Boiss.)Damboldt has been noted since the inception of this name [19].This plant was described as a narrow endemic from the volcanic mountain range of Köroglu in Bolu province [19,20], differing from subsp.pontica only by the entire bracts instead of dentate bracts.Damboldt only had access to one collection (Akman nº 3051, 14 VII 1975) and in the protologue indicated (holo.ANK), while in Flora of Turkey [20] wrote "Type (holo E! iso.ANK).The current authors have found one specimen in E (E barcode E00913665) identified as type by a manuscript label by Damboldt.This may imply that the only indication of ANK for the type in the protologue is a typographical error that deleted the reference to "E!".If this were the case, the fact that at least two specimens from the original material collected by Akman exist (in E and ANK) and the unfortunate putative misprint designating as holotype some material explicitly not seen by Damboldt, and therefore, not used by him to prepare the protologue, would leave this name without proper typification.Nevertheless, the absence of the "!" after ANK [19,20], indicating that this material was unseen by this author, could also be attributed to a typographical error.For the sake of precaution, the current authors will be

Jasione tmolea
This taxon is recognized at the subspecies rank subordinated to J. supina by Damboldt [20], Greuter et al. [17], and Lammers [4], referring to a narrow endemic from Mount Bozdagh, the ancient Mount Tmolus, in Izmir province, Turkey.Stojanov [13] described this name citing three different collections, one by Balansa (nº 333 July 1854, Sommet du Tmolus Occidentalis, au dessus de Y'aila de Bozdagh), one by Boissier (s.n., 1866 Smyra: Tmolus) and one by Frivaldsky (s.n.1845, Smyrna, sub Phyteuma).Damboldt [20], in the Flora of Turkey and the East Aegean Islands, listed these three collections and indicated them as "syntypes" in the G and W herbaria.The current authors have found several specimens of the Balansa 333 collection in P (P barcodes P00270579, P00270580, and
