In this paper, integrating field surveys and literature data, an analysis of
Ophioglossum lusitanicum plant communities and related 92/43/EEC habitats are reported for Italy. Two new syntaxa,
Euphorbio exiguae-Ophioglossetum lusitanici ass. nova hoc loco and
trifolietosum scabri subass. nova hoc loco of the
Rumici bucephalophori-Ophioglossetum lusitanici were described in the Apulia and Campania regions.Both types of vegetation identified in Apulia, Campania, and Sicily regions represent two different aspects of the same priority habitat: “pseudo-steppe with grasses and annuals of the
Thero-Brachypodietea” (habitat code 6220*). A phytosociological and ecological dataset of the literature and new field surveys highlighting the soil type as parameters affecting the vegetation cover of this small fernlike plant, with the
Trachynion distachyae Rivas–Martínez, 1978 alliance on calcareous soils and
Helianthemion guttati Br.-Bl. in Br.-Bl. et al., 1940 alliance on volcanic soils. Many species of other types of annual meadows have been identified within
Ophioglossum communities due to the very small patches of land, where they have been found, and ecological conditions that facilitate this phenomenon of the transgression of other therophytes species.
