General: Desert Broom-rape (Orobanche cooperi) is
a parasitic plant that has no chlorophyll. Broom-rapes attach to
the roots of other plants and sucks sugars and nutrients from
them. Desert Broom-rape usually has a single, short above-ground stalk,
from which flowers emerge. The stem and the flowers are purplish.
Desert Broom-rape is an uncommon component of vegetation communities in dry,
well-drained sandy and gravelly areas on desert flats, bajadas, and
moderate slopes in the Lower Sonoran (Creosote-Bursage
Flats) and Upper Sonoran (Mojave Desert Scrub) life zones.
Family: Broom-rape (Orobanchaceae).
