Dalea reverchonii (S. Watson) Shinners
Comanche Peak Prairie Clover
Fabaceae (Pea Family)
Synonym(s): Petalostemon reverchonii
USDA Symbol: DARE2
Comanche Peak prairie-clover is a low, spreading perennial, which appears as a dense, mat-forming rosette up to 16 inches in diameter. Numerous thick, 3 inch long spikes of rose-pink to magenta-purple flowers bloom in May, before other Dalea species, and continue through June. The smooth, alternate, pinnate leaves are about an inch long.
This elusive prairie-clover has been found only in a narrow band through three counties in north-central Texas. Julien Reverchon first collected this member of the pea family in 1882 from "the rocky top of Comanche Peak". Repeated surveys failed to re-locate that particular population (TPWD, 2003), until Spring of 2003 when a few plants were again found on Comanche Peak (Carr, personal commmunication).
