Nolina microcarpa is a species of the genus Nolina in the asparagus family (Asparagaceae). An English common name is "Sacahuista Beargrass".

description

Nolina microcarpa grows without a trunk and forms clumps of 1.2 to 2 m in diameter. The variable, grass-like, light green to yellow-colored, concave-convex, falling to the ground, leaves are 60 to 140 cm long and 5 to 12 mm wide. The leaf margins are serrated.

The inflorescence , which has short branches in the leaves , becomes 0.3 to 0.8 m long. The pink flowers are 1.5 to 3.5 mm long. The flowering period is in June.

The round capsule fruits , woody when ripe, are 3 to 5.5 mm in diameter. The brown, spherical seeds are 3 mm in diameter.

Nolina microcarpa is frost hardy to minus 20 ° C in Europe . She is hardly known.

Distribution and systematics

Nolina microcarpa is common in the US states of Texas and New Mexico and in Mexico in the states of Chihuahua and Sonora at altitudes of 1000 to 2000 m. It grows in grasslands, on stony ground on flat hills and is associated with Yucca baccata and various types of cacti.

Nolina microcarpa is a member of the Microcarpae section . The appearance is similar to the geographically isolated Nolina palmeri found on Baja California , but it has stiffer and shorter leaves.

The first description was in 1879 by Sereno Watson . A synonym is Beaucarnea microcarpa Baker .
