MOSSES & LIVERWORTS
Systematic
recording of mosses and liverworts in Greece lacks the long tradition of study
applied to the vascular plant flora and it is therefore not surprising that no
bryophyte records from Thásos were included in Flora Aegaea (Baumgartner 1943).
The first modern bryophyte checklists for Greece (Preston 1981, 1984a&b)
present species accounts based on regions and do not contain any locality
information. In fact, knowledge of the bryophyte flora of Thásos rests largely on the
efforts of Enno Damm and Ruprecht Düll (Damm 1989; Damm & Düll 1995), who undertook surveys on the
island in 1988 and 1994 respectively. Their checklist of the bryophyte flora,
incorporating records from Townsend (1977), includes 33 liverwort and 142 moss
species. Düll (1995) lists 152 liverworts and 455 mosses for Greece and there
are presumably many more bryophyte species still to be recorded on Thásos.
None of the liverwort species currently known from the island
appear to be particularly rare but two taxa, Cephalozia hampeana and Marchantia
polymorpha var. aquatica, have not been reported elsewhere in Greece
according to Düll (1995). Similarly with the mosses, where Ditrichum
cylindricum and Trichostomum brachydontium var. cuspidatum
are known in Greece only from Thásos (Düll 1995).
