sulum, Macrohymenium acicodon (Asian genus), Polytrichum subformosum. Madagascar-East African elements occurring also in South Africa: Jamesoniella purpurascens, Leucobryum isleanum, Macromitrium tristratosum, Leucodon capensis, Prionodon ciliatus, Orthostichopsis subimbricata

, Squamidium biforme, Papillaria africana, Eriopus asplenioides, Thuidium borbonicum, Entodon geminidens. These two groups are highly interesting from biogeographical point of view. Most of them were not known before from continental or East Africa. 41 out of the 57 species are restricted in East Africa to the area of the old cristalline ,,Inselberge", only 4 are limited to the young volcanic area. These old cristalline massifs, where they coincide with favourable climatic conditions at the eastern edge of the great Central African Plateau, form a chain of forest covered inselbergs from S Kenya through Tanzania to Malawi. (Taita, Maungu and Kasigau Hills in Kenya, Pare, Usambara, Kanga, Nguru, Ukaguru, Uluguru, Usagara and Uzungwe Mts. in Tanzania, Nyika Plateau and Mulanje Mts. in Malawi. The Cherangani Hills in North Kenya, the Ruwenzori Mts. themself, and the Gorongoza and Inyanga Mts. near the Mozambique — Rhodesia border also may belong to this group. (See Map 7). The analysis of the phenomenon, that most Madagascar elements, which occur in East Africa, are restricted to the area of these hills and do not occur in the volcanic mountains, probably will shed light on some problems of the relations between the continental and insular East African floras. West African insular elements, party common with Madagascar as well: Cololejeunea leloutrei, Euosmolejeunea montagnei, Syrrhopodon quintasii, Tayloria thoméana, Regmatodon secundus, Mittenothamnium fruticellum. Elements of Mediterranean and Atlantic Europe with disjunction in the East African mountains, like Erica arborea among the phanerogams. This interesting group occurs mostly on the young volcanoes in East Africa and may be more widespread in South Africa: Lophocolea fragrans

, Gongylanthus ericetorum (also in W Africa), Barbula rigidula

, Bryum canariense, Bartramia stricta (-f- Colorado, California), Pteroganium gracile (-f- California), Leptodon smithii {-f- Colorado, Chile, Australia, New Zealand), Haplocladium angustifolium. Widely distributed Tropical African elements: Plagiochila fusifera, P. heterostipa, Cololejeunea africana, C. bolombensis, C. eristata, C. duvignaudii, Diplasiolejeunea albifolia, Odontolejeunea tortuosa, Caudalejeunea hanningtonii, Mastigolejeunea carinata, Phragmilejeunea molleri, Cheilolejeunea newtonii, Cheilolejeunea principensis, Lejeunea grossedentata, L. isophylla, L. kamerunensis, L. setacea, Racopilum africanum, Taxilejeunea conformis, Brachymenium borgenianum, Acropoium megasporum, > Map 7.
