SKELETONWEED ERIOGONUM-Eriogonum deflexum Torr.

DESCRIPTION-Skeletonweed eriogonum is a stiff, flat-topped, bushy annual, 1/2 to 1 1/2 feet high, reproducing only by seed. The stems are branched above and leafless, except at the base where a few soft, white hairy, heartshaped leaves appear, then wither and drop off. The many small white or pink flower clusters hang downward on short stalks about 1/8 inch long. The 3-angled dark brown seeds (achenes) are l/2 inch long or less.

DISTRIBUTION-An abundant and conspicuous weed on dry, disturbed or rocky soil, on roadsides, vacant lots, city streets, waste places, or eroded areas on desert and desert grassland ranges; 150 to 4,000 feet elevation; flowering most of the year, but principally from March to November. An extremely drought-resistant plant, flourishing with little or no water. The stems turn a maroon color in the winter, and are very conspicuous.
