Homaliodendron decompositum (Brid.) Wagn. reduced to synonymy with H. flabellaturn (Sm.) Fleisch

Abstract

Four small moss families found in Malawi are reviewed, and keys are provided to all taxa known in Malawi (and usually to all known in Africa). Regmatodontaceae is shown to contain only one species in Africa, but both known species are keyed. Rhachitheciaceae, contains three genera in Africa (which are keyed), only one of which occurs in Malawi, and for this genus a key is provided for all three African species. Rhacocarpaceae contains only two species in Africa, which are keyed, only one of which is known from Malawi. Rhizogoniaceae contains two genera and three species in Africa.
