Abstract

Abstract During preparation for a revision of the genus Paspalum for America, two new taxa from Brazil were recognized as previously undescribed species. Paspalum plowmanii from Bahia, Goias, and Mato Grosso is related to P. macranthecium. from which it differs by its non-stipitate spikelets, with upper glume 3/4 the length of the spikelet, and by having a membranous upper glume and lower lemma. Paspalum filgueirasii from Goias, Brazil, is related to P. proximum Mez, from which it differs by having a single and erect raceme. Both species are described, illustrated, and compared with putatively related species. A key to the new species and related taxa of Paspalum is also presented.
