Identification
Taxonomic CommentsPaspalum is a genus of more than 300 species, found mostly in the New World. The genus is quite easily identified by the neat row of spikelets along each side of a flattened rachis (inflorescence branch), and also by the hemispherical outline of each spikelet. In some species there are only 2 such inflorescence branches, paired at the stem summit; in most of our species there are 3-4 branches; and in a few there may be many. Keys ask whether spikelets are paired or not -- that is, at each node on each side of the rachis there are pairs of spikelets on tiny stalklets. Care must be taken with a hand lens to make sure there are 2 stalklets at each node, as frequently one of the two spikelets will not grow. Non-paired or single spikelets will clearly have only a single stalklet per node.
