It is usually dioecious, infrequently monoecious, or rarely synoecious. On the basis of his molecular studies, Columbus (1999) recommended including it and several other small, usually monoecious or dioecious genera in Bouteloua. Morphologically, the segregate genera differ from Bouteloua only in their pistillate panicles and spikelets and their reproductive mode, but not in their vegetative and staminate structures. Buchloë is maintained here pending corroboration from other studies.</p> |tables= |references={{Treatment/Reference |id=beetle1950a |text=Beetle, A.A. 1950.
