Περίληψη:
Greece is characterized by high plant diversity (5800 species) and
endemism (15.6%). This study attempts a first overall assessment of the
taxonomy, distribution, traits and conservation status of the Greek
endemic plants. The endemic species belong to 56 families and 242
genera. Most of the endemic plants have a narrow geographical and
altitudinal distribution range. The southern floristic regions are
richer in endemic species. The species area relationships for endemics
(EARs) for island and continental floristic regions explain over 50% of
the variation in number of species and are characterized by steep
curves. Analysis of the distributional pattern of the endemics by
similarity coefficients offers useful insights into the palaeogeography
and biogeography of Greece. The endemic species occur at all altitudes,
but the altitudinal distribution shows a predominance of local endemics
at 0-600 m in the island regions and in higher zones in the continental
regions. The life form spectra show a predominance of hemicryptophytes
and chamaephytes. This trait seems indicative of their habitat and
adaptive strategy and may be related to speciation processes. The
overview of the conservation status of the Greek endemics indicates that
over 40% of the taxa are threatened or near threatened. (C) 2010 The
