- Abstract
Chromosome numbers and observations on meiotic chromosome behavior of 26 taxa of South American Paniceae are given. Of these 18 are new counts including the monotypic genera Plagiantha and Tatianyx. The taxa that were studied are Axonopus anceps (n = 30), A. pressus (n = ca 20), A. siccus (n = 10), Digitaria sacchariflora (n = 18), Panicum assurgens (n = 9), P. cabrerae (n = 9), P. cipoense (n = 20), P. cyanescens (n = 18), P euprepes (n = 20), P aff heliophilum (n = ca 30), P molinoides (n = 20), P. penicillatum (n = ca 27), P. poliophyllum (n = 20), P. stenophyllum (n = 10), P wettsteinti (n = 9), Paspalum coryphaeum (n = 10), P. ligulare (n = ca. 20), P millegrana (n = 20), P minarum in = 20), P. pumilum (n = 10), P. scutatum (n = 10), Plagiantha tenella (n = 10), Streptostachys asperifolia (n = 10), Tatianyx arnacites (n = ca. 30), Urochloa sp. (n = ca. 14), and Urochloa acuminata (n = 13). The count given for Panicum cyanescens is different from the previously reported. Morphological as well as taxonomic considerations are given about the relationships of some of these taxa.
