12 hepatics and 32 mosses are reported new to Uganda, 1 moss being also new to Africa, and 1 liverwort new to mainland Africa. Ectropothecium plumigerum (Broth.) Hedenäs is a new combination (basionym: Isopterygium plumigerum Broth.) with a new synonym Taxicaulis plumirameus Müll.Hal. nom. nud., and Taxiphyllum maniae (Renauld & Paris) M. Fleisch. is a new synonym of Taxiphyllum taxirameum (Mitt.) M.Fleisch. Three mosses are removed from the Uganda list.
Eine komplette Liste aller auf den Seychellen gefundenen Laubmoose wird gegeben, die 107 Arten enthält. Darin werden 24 Arten angeführt, welche von S. Porembski im Frühjahr 1995 auf den Seychellen gesammelt wurden. Sieben Arten [Acanthorrhynchium loucoubense (Besch.) Fleisch., Brachymenium exile (Dozy & Molk.) Bosch & Lac., Campylopus robillardei Besch., Campylopus nanophyllus C. Müll. in Broth., Fissidens crispulus Brid., Leucoloma sinuosulum C. Müll. ex Besch. und Vesicularia albo-viridis (Ren.) Broth.] werden neu für die Seychellen nachgewiesen. Acroporium punctuliferum (Thw. & Mitt.) und Luisierella barbula (Schwaegr.) Steere Fleisch. sind neu für Afrika. Die floristischen Bezüge der Laubmoosflora der Seychellen zu denen der anderen ostafrikanischen Inseln wird kalkuliert.
Manual of tropical bryology
(2003)
Bryophytes belong to the oldest land plants. They existed already in the Palaeozoic 300 mio years ago in forms which were hardly different from the extant species. They remained relatively unchanged with relatively low evolution rates (and are thus often called a „conservative“ plant group), but could successfully establish themselves in an always varying environment from Devonian swamps to Permian forests, Mesozoic deserts and as epiphytes in Tertiary rainforests. They are not eaten by snails or insects, and are resistant against fungi and bacteria.
