WOOLLY LOCO
[39.] Heron-bill
Also called “alfileria,” this species and its close relative, Texas filaree (Erodium texanum) are both early blossoming annuals, often widespread on plains and mesas, February to May. The flowers, although abundant, are small and so hidden in low-growing foliage that they rarely create a mass display. Texas filaree is native to North America, but alfileria is thought to have come from Europe with the Spaniards, and is now naturalized throughout the Southwest. Corkscrew-like appendages of the fruits are tightly twisted when dry, but untwist when moist, literally screwing the sharp-pointed fruits into the soil. Both species are excellent spring forage for livestock.

[40.] Creosotebush
Often erroneously called “greasewood,” creosotebush is generally recognized as the most adaptable of all desert plants, and a definite indicator of the Lower Sonoran Life Zone. The shrubs cover thousands of square miles, often in pure stands, and flower throughout much of the year, but most profusely in April and May. Fuzzy white, globular fruits are almost as spectacular as the flowers. The plant can endure long periods of drought. Following rains its foliage gives off a musty, resinous odor, suggestive of creosote, stimulating the Mexican name hediondilla (little stinker). In Mexico the plant is considered to have medicinal values and many uses. The Pima Indians boiled the leaves, using the decoction as an emetic and to poultice sores. They used the lac, found as an incrustation on the branches, to cement arrow-points and to mend pottery.
