About plant names...

Spiny menodora is native to the southwestern United States, especially the Mojave desert. It prefers arid moun­tain slopes, dry mesas, and canyons, at elevations of 3500-6500' (1-2.0 km).

Plants: Densely branched shrubs are 8-20" (20-50 cm) tall. Branches are round and green or gray, and puberulent (cov­ered in fine hairs). They taper to sharp spines.

Leaves: Alternate, fleshy, in small clusters, sessile, and linear to oblanceolate.

Flowers: Red to pink buds open to white flowers with yellow centers. Each flower usually has 5-6 lobes, and is less than ⅜" (1 cm) around. Flowers appear from Aprill to May.

Fruits: Round, shiny brownish capsules usually contain two seeds.
