@ARTICLE{TreeBASE2Ref22994, author = {Fernando O. Zuloaga and M. Amalia Scataglini}, title = {Phylogeny of Sections Clavelligerae and Pectinatae of Panicum (Poaceae, Panicoideae):establishment of the new subtribe Dichantheliinae and the genus Adenochloa}, year = {2014}, keywords = {Adenochloa, ndhF phylogeny, Paniceae, Panicum, Clavelligerae, Pectinatae.}, doi = {}, url = {http://}, pmid = {}, journal = {Plant Systematic and Evolution}, volume = {}, number = {}, pages = {}, abstract = {Taxonomic features of African species of Panicum sections Clavelligerae and Pectinatae are reviewed and compared with Dichanthelium and other taxa in tribe Paniceae. The new subtribe Dichantelineae is proposed on the basis of molecular and morphological characters, being non-Kranz species, with membranous-ciliate ligules, inflorescences lax and open, with spikelets ellipsoid to oblongoid, and upper anthecium indurate. Within this subtribe, the new genus Adenochloa is also proposed on the basis of chloroplast ndhF sequences and morphological characters, i.e., plants growing at forests edges or mountain grasslands, blades with or without clavellate hairs, inflorescences lax and open, usually with clavellate hairs on the main axis, branches, and pedicels, spikelets ellipsoid to oblongoid, glabrous, with the lower glume present, 1/3 to more than 1/2 the length of the spikelet, upper glume 7-11-nerved, lower lemma 5-9-nerved, and upper anthecium indurate, pilose or glabrous, to include 14 species from Africa and Madagascar. The new combinations: Adenochloa adenophylla, A. adenophora, A. bullockii, A. claytonii, A. ecklonii, A. flacciflora, A. habrothrix, A. hymeniochila, A. lukwangulense, A. nigromarginata, A. pectinella, A. peteri, A. pole-evansii, A. sadinii are proposed and the new genus is compared with other genera of the tribe Paniceae. Also, lectotypes are designated for Brachiaria sadinii, Panicum adenophorum, P. adenophyllum, P. ecklonii, P. katentaniense, P. kisantuense, P. hymeniochilum, P. hymeniochilum var. glandulosum, P. snowdenii, and P. scandens; Panicum glanduliferum and P. omega are new synonyms of Adenochloa hymeniophila and A. pectinella, respectively. Finally, new illustrations are provided for 6 species of the new genus.} }
