Desert, semi-desert. Open shrub and grasslands. Spring.
The lobed, undulating leaves of Mentzelia pterosperma are large, distinctive, and eye-catching. The stem is stout, straight, and quite light white/yellow; plants grow to over a foot tall. The buds are unusual in both their orange-to-green color and their open flared ends. Flowers often open at night.
Leaves, buds, stems, and fruit of plants in Loasaceae are covered with stiff, hooking hairs that cling to fingers.
"Pterosperma" means "winged seed".
