内容記述 | Disjunctive distribution of some bryophytes between East African Highlands and the subantarctic region are discussed. The subantarctic bryophytes in East African Highlands can be classified into three groups : Group 1 includes species growing on wet rocks in periglacial environment of the Afroalpine region such as Andreaea subulata, Bryum ellipsifolium and Rhacocarpus purpurascens; Group 2 includes those growing on trunks and rocks of forests in the Afromontane region such as Clasmatocolea vermicularis, Catagonium nitens and Dicranoloma billardieri; Group 3 is represented by Aongstroemia julacea on bare land of the Afroalpine region. The bryophytes of Groups 1 and 2 seem to be old elements which have been originated from the Gondwanaland. Group 1 seems to have been diffused from the region of Group 2 after the last glaciation. Group 2 has been restricted in the Afromontane forest since the Late Cretaceous. Group 3 is considered to have been newly distributed after the last glaciation because it is found in young volcanoes erupted in the Quaternary. The ice-age aridity in Africa affected the distribution of bryophytes severely. The Afromontane forests in the inselbergs of East Africa seem to have played an important role as refugia for Groups 1 and 2 during the glacial age. | |||||||
