Other info. - This species can be found throughout much of Missouri but is apparently absent in the bootheel portion of the state. The plant can be easily identified while in flower becasue of its pendulous spikelets. The pustular bases of the hairs at the base of the leaf blade are another good characteristic to look for.
The Missouri material belongs to variety curtipendula. Two other varieties occur in the southwestern U.S. and Latin America.
George Yatskievych writes that "sideoats grama is one of the most important and widespread range grasses in the Great Plains."
