79. Louisiana broomrape

Lacking chlorophyll and parasitic on the roots of bur-sage and other

desert composites, broomrape is so unusual in appearance as to attract

immediate attention. Although fairly common in low-elevation deserts

from west Texas and Mexico to southern California, it is occasionally

found as far north as southern Utah and Nevada and at elevations up to

7,000 feet. The rather inconspicuous flowers appear from February to

September. Navajo Indians made a decoction of the plant as a treatment

for sores. Desert Indians ate the tender stems in springtime.
