General: During most of the year, Littleleaf Ratany (Krameria erecta) is a many-branched shrub that forms a low mound of short, thin branches. During the growing season, the plant puts on short, narrow leaves and purple flowers.
Littleleaf Ratany is a fairly common component of vegetation associations in washes and on rocky bajadas in the Upper Sonoran (Mojave Desert Scrub) life zone. This is the only species of Ratany that grows in Red Rock Canyon NCA and the Spring Mountains. Littleleaf Ratany, and another species, White Ratany, occur together in the northern Lake Mead Region (e.g., Valley of Fire and northeastward). |
