Under the name "bison grass" the literature may also refer to another North American grass - Buchloe (Buchloe dactyloides) - a perennial dioecious long-rhizomed plant that is an excellent substitute for lawn grasses in arid areas, requiring no watering, feeding or mowing and reaching a height of only 10-20 cm.
