Paspaleae is a tribe of the Panicoideae subfamily in the grasses (Poaceae), native mainly to the tropical and subtropical Americas but with a number of species introduced to other regions. It includes roughly 680 species in 39 genera.[2] Species in this tribe use either of the C3 or C4 photosynthetic pathways.[3]
The genera of Paspaleae used to be included in the Paniceae but were assigned to a new tribe following molecular phylogenetic analyses in 2012. The Paspaleae have an ancestral number of chromosomes (monoploid number) of x = 10, unlike the Paniceae sensu stricto with x = 9, and are more closely related to the tribes Andropogoneae and Arundinelleae.[4] The tribe is subdivided into three subtribes, with one genus, Reynaudia, unplaced (incertae sedis) and probably basal to the other genera.[2] The genus Lecomtella is sometimes included but a study suggested this genus was a distinct clade and best treated as separate tribe, Lecomtelleae.[5]
