Chromosome numbers and ploidy levels of 24 accessions of 17 species of tribe Panicoideae from Argentina, Cuba and Brazil are given. Most of the studied species are endemics. The studied taxa are: Axonopus aureus P. Beauv., Dichanthelium stipiflorum (Renvoize) Zuloaga, Dichanthelium aequivaginatum (Swallen) Zuloaga, Dichanthelium surrectum (Chase ex Zuloaga & Morrone) Zuloaga, Homolepis isocalycia (G. Mey.) Chase, Paspalum arenarium Schrad., Paspalum blodgetii Chapm., Paspalum capillifolium Nash, Paspalum coryphaeum Trin., Paspalum distortum Chase, Paspalum durifolium Mez, Paspalum lindenianum A. Rich., Paspalum oligostachyum Salzm. ex Steud., Paspalum pumilum Nees, Paspalum scutatum Nees ex Trin., Paspalum strigosum Döll ex Chase, and Plagiantha tenella Renvoize; of these, the chromosome numbers of Dichanthelium aequivaginatum, D. stipiflorum, D. surrectum (n = 9), Homolepis isocalycia (n = 20), Paspalum capillifolium, P. distortum, P. lindenianum, P. oligostachyum and P. strigosum (n = 10) are presented for the first time. New diploid cytotype (n = 10) for Paspalum blodgettii was found.
