Bouteloua dactyloides (Nutt.) Columbus (redirected from: Buchloe dactyloides (Nutt.) Engelm.)
Family: Poaceae [Buchloe dactyloides (Nutt.) Engelm.] Linda Ann Vorobik and Karen Klitz, Illustrators	Flora of North America Resources Neil Snow Ligules 0.5-1 mm; blades 2-15 cm long, 1-2.5 mm wide. Staminate spikelets 4-6 mm long, 1.3-1.8 mm wide; anthers 2.5-3 mm. Pistillate spikelets to 7 mm long, about 2.5 mm wide. Caryopses 2-2.5 mm. 2n = 20, 40, 56, 60. Bouteloua dactyloides is a frequent dominant on upland portions of the semi-arid, shortgrass component of the Great Plains, ranging from the southern prairie provinces of Canada through the desert southwest of the United States to much of northern Mexico. Collections from east of the Mississippi River and south of the Ohio River probably represent recent introductions. Bouteloua dactyoides provides valuable forage for livestock and wildlife, and withstands heavy grazing. It may be confused in the southern portion of its range with Hilaria belangeri, which consistently has pilose nodes, or in the Big Bend region of Texas with Cathestecum erectum, which has three spikelets per node and distinctly awned lemmas. NOTE: This description will be augmented in the near future with information from the generic description of Buchloe.
