The hepatic flora of SW Asia strongly resembles that of the Mediterranean area; one notes only some Asiatic elements in the E and tropical African ones in the S. The only phytogeographical unit sufficiently well delimited at the level of hepatics corresponds to the Mesogean area, probably colonised, after the drying up of the Tethys, by species adapted to a dry climate and probably coming as much from the N as the S. This hepatic flora, unlike that of the phanerogams, is thus not diversified.
