Abstract:

Abstract Chromosome numbers and meiotic behavior of 60 individuals of American Paniceae, Poaceae, are provided, including six previously uncounted species: Axonopus andinus G. A. Black (2n ?=? 20), A. iridifolius (Poepp.) G. A. Black (2n ?=? 20), Dichanthelium hebotes (Trin.) Zuloaga (2n ?=? 18), Paspalum geminiflorum Steud. (2n ?=? ca. 20), P. heterotrichon Trin. (2n ?=? 20), and Setaria tenacissima Schrad. ex Schult. (2n ?=? 36). Of the remaining 54 counts, 17 correspond to new ploidy levels in species of Echinochloa P. Beauv., Eriochloa Kunth, Hymenachne P. Beauv., Panicum L., Parodiophyllochloa Zuloaga & Morrone, Paspalum L., and Setaria P. Beauv., and 37 are confirmations of previous reports.Abstract Chromosome numbers and meiotic behavior of 60 individuals of American Paniceae, Poaceae, are provided, including six previously uncounted species: Axonopus andinus G.
