Common Name: buffalograss Duration: Perennial Nativity: Native Lifeform: Graminoid General: Perennial, usually dioecious, strongly stoloniferous, sometimes mat-forming, with stems 1-30 cm, erect, mostly unbranched, with pistillate inflorescence branches much shorter than staminate inflorescences, usually with glabrous nodes. Vegetative: Basally tufted leaves, blades 2-15 cm long, 1-2.5 mm wide, apices involute; sheaths open, rounded, often sparsely pilose near the collar, ligules membranous or of hairs, 0.5-1 mm. Inflorescence: Staminate inflorescence terminal, usually exceeding upper leaves, panicles of 1-3 racemosely arranged, unilateral, pectinate branches, not enclosed at maturity; staminate spikelets 4-6 mm, with 2 florets, glumes unequal, glabrous, 1 or 2 veined, lemmas, 3-veined, glabrous, unawned; pistillate inflorescences terminal, panicles partially within bracteate leaf sheaths, branches 2-3, 2.5-4.5 mm, burlike with 3-5 spikelets; disarticulation at base of panicle branches; pistillate spikelets with 1 floret, almost enclosed by upper glumes; lower glume irregular and reduced, upper globose, white, indurate with 3 awnlike teeth; lemmas membranous, glabrous, unawned or shortly 3-awned. Ecology: Found on limestone soils around 5,000 ft (1524 m); flowers fall. Notes: Widespread in the plains, but rare in Arizona. Found in Coconino and Yavapai counties. In its southern range it can be confused with Hilaria belangeri, which has pilose nodes, and Cathestecum erectum (now: Bouteloua erecta) which has three spikelets per node and distinctly awned lemmas. Ethnobotany: Unknown, but other species in the genus have many uses. Etymology: Bouteloua named for brothers Claudio (1774-1842) and Esteban (1776-1813) Boutelou Agraz, Spanish botanists and horticulturalists; while dactyloides comes from Latin dactylis and Greek daktylos for finger, referring to the grass as finger-like. Synonyms: Buchloe dactyloides, Bulbilis dactyloides, Sesleria dactyloides, several others, see Tropicos Editor: SBuckley, 2010
