Chromosome Numbers and Ploidy Levels of Some Paniceae and Paspaleae Species (Poaceae, Panicoideae)

Abstract 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 aequivaginatum (Swallen) Zuloaga, D. stipiflorum (Renvoize) Zuloaga, D. surrectum (Chase ex Zuloaga & Morrone) Zuloaga, Homolepis isocalycia (G. Mey.) Chase, Paspalum arenarium Schrad., P. blodgettii Chapm., P. capillifolium Nash, P. coryphaeum Trin., P. distortum Chase, P. durifolium Mez, P. lindenianum A. Rich., P. oligostachyum Salzm. ex Steud., P. pumilum Nees, P. scutatum Nees ex Trin., P. strigosum Döll ex Chase, and Plagiantha tenella Renvoize; of these, the chromosome numbers of D. 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. A new diploid cytotype (n = 10) for Paspalum blodgettii was found.

期刊介绍： The Annals of the Missouri Botanical Garden is a quarterly international journal primarily devoted to systematic botany and evolutionary biology. We encourage submissions of original papers dealing with significant advances in the taxonomy, phylogeny, biogeography, paleobiology, and evolution of plants, and in conservation genetics and biology, restoration ecology, and ethnobiology, using morphological and/or molecular characters, field observations, and/or database information. We also welcome reviews and papers on conceptual issues and new methodologies in systematics. Important floristic works will also be considered. Symposium proceedings discussing a broader range of topical biological subjects are also published, typically once a year. All manuscripts are peer-reviewed by qualified and independent reviewers.
