H.B.K.) Calamagrostis sesquitriflora Steud. Syn. Gram. 190. 1854. (Type from Toluca, Mexico. Steudel's
description of the spikelet is erroneous; the type has been examined and found to have a single
floret with awned lemma; the large spreading palea is obviously the "awnless floret" referred
to by Steudel.)

Type locality: Near Toluca, Mexico. Distribution: Paramos, Mexico and Guatemala.
