520 _aThe new genus Trichanthecium (Poaceae, Paniceae) is proposed on the basis of shared morphological characters, including presence of membranous ligules, lax and open inflorescences, ellipsoid to obovoid and pilose or glabrous spikelets, the lower glume nearly 1/2 to as long as the spikelet and (1-) 3 nerved, the upper glume 3-5 -nerved, and the upper anthecium indurateand covered with globose or elongated bicellular microhairs and simple papillae. This generic delimitation was confirmed with molecular phylogenetic studies utilizing analyses of chloroplast ndhF and rpoA sequences. Morphological characters and phylogenetic aspects of Panicum and other genera of Paniceae are discussed. Trichanthecium comprises 38 American and African species, wich were previously assigned to Panicum sections Parvifolia and Verruculosa. Full synonymies and descriptions, and a key are provived; all species are mapped, and most are illustrated. Lectotypes are designated for Isachme margaritifera Chiov., I. trochainii, A. Camus, Punicum carannasense Mez, P. cyanescens var. rigidiusculum Döll, P.drosocarpum Stapf, P. frederici Rendle, P. frederici var. mimor Rendle, P. fulgens Stapf, P. fulgens var. pubescens Robyns, P. gracilicaule Rendle, P. helobium Mez ex Henrard, P. ianthum Stapf, P. juncifolium Stapf, P. mueense Vanderyst, P. natalaense Hochst, P. plagianthum Stapf. P. pubiglume Stapf, P. schwackeanum Mez, P.sublaetum Stapf, P.subulatum Spreng. A neotype is designated for Aira distichophylla Spreng. Thirty-eight new combinations are proposed: T.arctum, T. auricomum, T. brazzavillense, T. cyanescens, T. dinklagei, T. distichophyllum, T. filifolium; T. fonticolum, T. glaucocladum, T. gracilicaule, T.granuliferum, T. ichunense, T. machrisianum, T. margaritiferum, T. micranthum, T. mueense, t. natalense, T. nervatum, T. nervosum, T. noterophilum; T. nutabundum, T. orinocanum, T. pandum, T. parvifolium, T. petilum, T. petrense, T. polycomum, T. praealtum, T. pseudisachne, T. prylarium, T. rivale, T.schwackeanum, T. strictissimum, T. tenellum, T. tepuianum, T. wettsteinii, T.yavitaense.
