Grimmia pseudo-anodon Deguchi, previously known only from Peru, is reported as new to Bolivia. The specimens are from packets labelled as Coscinodon trinervis, collected by Herzog in 1911. Grimmia pseudo-anodon is distinct by its non-plicate leaves and straight, centrally attached seta. This is a range extension of some 300 km and an elevational increase of about 1000 m.
Sixty taxa of mosses, mainly pleurocarps, are reported from the Mascarenes. Two are new to Afr.3 sensu Index Muscorum, i.e., Brachythecium plumosum (Hedwig) Schimper in BSG and Palamocladium sericeum (Jaeger) C.Müller. Nine are new to the Mascarenes, i.e., Brachythecium decurrens Cardot, Callicostella parvocellulata Demaret & P.Varde, Helicodontium lanceolatum (Hampe & C.Müller) Jaeger, Lepidopilum carrougeauanum Thér. & P.Varde, Mittenothamnium microthamnioides (Geh.) Wijk & Marg., Orthostichopsis longinervis (Ren. & Cardot) Broth., Plagiothecium nitens Dixon, Rhynchostegium comorae (C.Müller) Jaeger and Trachypus bicolor var. hispidulus (C.Müller) Cardot. One is new to Mauritius and Réunion, but known from Rodrigues, i.e., Meiothecium madagascariense (Bridel) Broth. Five taxa are new to Mauritius, i.e., Callicostella salaziae (Besch.) Broth., Lopidium struthiopteris (Bridel) Fleischer, Macrohymenium acidodon (Mont.) Dozy & Molk., Orthostichella pentasticha (Bridel) Buck and Vesicularia lepervanchei (Besch.) Broth.
Im März 1996 wurde in den südlichen Drakensbergen eine Bestandsaufnahme der epiphytischen Moose durchgeführt. Dabei wurden 38 Moosarten, 12 Leber- und 26 Laubmoosarten, nachgewiesen. Die höchsten Artenzahlen wurden in einem Podocarpus-Wald gefunden, was auf ein feuchteres Bestandsklima und Schutz vor Feuer zurückgeführt wird. Eine Auswertung der Arealtypenspektren ergab, daß die Moosepiphyten aller untersuchten Waldtypen als auch ihre Trägerbäume nähere phytogeographische Bezüge zur afromontanen Vegetation haben, wohingegen in der gesamten Phanerogamen-Flora der Drakensberge das südafrikanische Florenelement überwiegt.
124 species of bryophytes, belonging to 46 families are reported for the Aberdare Mountains, of which 58 species are new for the Aberdares and 6 records are new for Kenya, indicated by * and ** respectively. The wetter, more humid southern and south-eastern parts of the range contain the greatest diversity of species, particularly in the montane forests while the drier northern part is poor in species.
