Notes: A charismatic shrub of deserts with its showy orange-red tubular flowers with 1 lobe above and 3 below and long, exserted stamens; distinguished by being pubescent all over; whitish, exfoliating older bark; opposite, lanceolate leaves; and inflorescences with clusters of flowers with glandular flower stalks. Summer rains stimulate stem growth, with flowers that are well adapted for hummingbird pollination. One of the better browse plants in the desert. Often found growing in shade. Ethnobotany: Potential use of nectar as sweetener, but no documented use. Etymology: Anisacanthus is from Greek anisos -unequal-, while Thurberi is for Dr. George Thurber (1821-1890) a botanist on the Mexican Boundary Survey in 1850-1854.
