Bouteloua eludens, colloquially known as Santa Rita grama or sometimes Santa Rita Mountain grama, is a grass species in the grama genus native to southern Arizona in the United States and northern Sonora in Mexico.[1] [2] [3]
Santa Rita grama is a perennial grass growing between 25cm (10inches) and 70cm (30inches) tall. Grass blades measures 1mm to 2.5mm wide; they are flat, firm, light green in color, and covered in a glaucous coating. Each blade measures 1mm to 2.5mm wide. The base of the plant is rhizome like. Inflorescences are borne in groups of 8 to 18.
Santa Rita grama prefers to grow at heights of 4000feet to 5000feet, and in dry rocky slopes or desert grasslands. It is known to live in the Santa Rita Mountains (from which it takes its name), the Santa Catalina Mountains, Nogales, and parts of Sonora. It is a fairly rare species across its range.
