Synonym(s): Aphyllon cooperi, Myzorrhiza cooperi, Orobanche cooperi ssp. cooperi, Orobanche cooperi ssp. latiloba, Orobanche ludoviciana var. cooperi, Orobanche ludoviciana var. latiloba
USDA Symbol: ORCO4
A fleshy plant with dense spikes, singly or in clusters, of bilaterally symmetrical, dark purple flowers.
The proper classification of this plant remains unclear. It is often considered a subspecies of Prairie Broomrape (Orobanche ludoviciana), a species widespread in the West, and its distinction from Spike Broomrape (O. multiflora) is also debated. All Orobanche species are parasites on the roots of other plants; this species is particularly common on White Bur Sage (Ambrosia dumosa), a shrubby member of the aster family (Asteraceae). It has also become a parasite on tomato crops in southeastern Californias Coachella Valley.
