| In Malesia the genus Tephrosia is represented by 20 species, native or introduced and naturalized, including 6 subspecies and 5 varieties; 4 species are restricted to Malesia. Two of these species are newly described: T. barbatala and T. elliptica; the former includes one new variety (var. glabra). Two new subspecies and one new variety are distinguished: T. filipes subsp. longifolia, T. purpurea subsp. barbigera, and T. maculata var. elongata. Two taxa are given a new status: T. maculata var. appressepilosa and T. pumila subsp. aldabrensis. Four species, T. dichotoma, T. repentina, T. coarctata, and Kiesera sumatrana are for the first time sunk into synonymy. A key to the taxa, synonymy, and full descriptions with plates and distribution maps are given. |

| This revision is a monographic treatment of the fern genus Microsorum (Polypodiaceae). To elucidate the problematic generic delimitation and systematic position of this genus an additional selection of 26 possibly related species was also studied. Most of these related species are traditionally placed in Colysis, Leptochilus, Neocheiropteris, Paraleptochilus, Phymatosorus (‘Phymatodes’), and Podosorus. In order to produce a natural classification an attempt is made to recognize monophyletic groups of species through cladistic analysis. The methods and underlying theories which have been employed are made explicit as much as possible. A suitable selection of intrinsic characters is used for analysis with the computer programs CAFCA, PAUP and HENNIG86. The... |

| The monotypic genus Urariopsis, based on Uraria cordifolia Wall., has been compared with several S.E. Asiatic species of Uraria. The species Uraria prunellaefolia, U. collettii, and U. barbata are considered to be most closely related to U. cordifolia. The pods of U. cordifolia and U. collettii consist of longitudinally flattened, peltate loments, those of U. prunellaefolia consist of laterally flattened, longitudinally arranged loments; in the other species the loments are laterally flattened and zig-zag folded. No correlating characters were found, and the differences in shape of the pods are not considered sufficient ground to distinguish groups on generic level. Notes on morphology, nomenclature, and geographic distribution are presented. |
