EAST AFRICAN BRYOPHYTES I. By M. BIZOT and T. PÓCS University of Dijon, France — Teachers' College, Eger, Hungary (Közlésre érkezett: 1974. február 28.) S u m m a г у 441 species of bryophytes are reported from East Africa, based on the collections made by T. Pócs, E. W. Jones, R. B. Faden and others. 115 of them are new for East Africa. Among them 4 are new for the whole tropical Africa, as Kurzia verrucosa, Tritomaria exsecta, Leptolejeunea epiphylla and Isopterygium seligeri = Dolichotheca silesiaca; 30 are new for continental Africa, previously known only from Madagascar and from the Mascarene Islands, as Bazzania borbonica, Chiloscyphus mascarenensis, Leucophanes rodriguezii, Macrohymenium acicodon, and others. 16 afro-alpine elements {partly endemic, partly circumboreal) are new for Kilimanjaro Mts., like Chandonanthus cavallii, Gymnomitrium laceratum, Plagiochila ericicola

, Tetraplodon mnioides, etc. Such elements are also reported from Uluguru Mts. (10, as Campylopus alpicolus

, Leucoloma volkensii) and from the Poroto and Rungwe Mts. in Southern Tanzania (8 species, and Campylopus procerus, Entodon vulcanicus, and others). The taxonomic position of Spoggodera cavallii = Oligotrichum cavallii is clarified. Leskeodon mniifolium (Hornsch.) Bizot as new combination is published. New synonyms are given for Ptychanthus striatus, Leptolejeunea epiphylla, Groutiella tomentosa, Squamidium biforme, Catagonium nitens, Eriopus asplenoides, Leskeodon mniifolium and for Regmatodon secundus. Neorutenbergia armata is synonymized with Rutenbergia usagarae and a new combination is created: Neorutenbergia usagarae. The generic name Jonesiobryum is proposed instead of Jonesia Bizot et Pócs. Preface Т. Pócs spent four years in Morogoro, Tanzania, as a senior lecturer in Botany, at the Faculty of Agriculture of the University of Dar es Salaam. This paper enumerates the first records of his bryophyte collectings, together with other collectors' material. (See the sites on Map. 1.) T . Pócs wishes to express his gratitudes towards the University of Dar es Salaam, which sponsored his research and collecting activity.
