Description
PLATE XXXV Dalea albiflora Gray, a diffuse or assurgent herb about 3-6 dm tall, finely pilosulous throughout, bearing in the fall months and sometimes again in spring many dense, cylindric, tassel-like spikes of small, pure white flowers. The plants vary in length and density of pubescence, and independently in diameter of the spikes, those shown here being of about medium length and thickness. The species is common in grassland and in open oak-pine woodland between 1050 and 2250 m in the Sierra Madre of Chihuahua and adjoining Durango, and in the floristically related mountain ranges about the headwaters of the Gila River in southwestern New Mexico, southeastern Arizona, and neighboring Sonora. Note the free inner petals that resemble those of the white prairie- clover, D. Candida, the slightly exserted stamens, and the deeply cleft androecium likewise recalling that of sect. Kuhnistera except that there are here ten filaments. Inflorescence × 1; stipules and leaflets × 5; the rest × 10. 1) summit of flowering stem; 2) stipules; 3) leaflets; 4) larger and smaller flowers; 5) calyx, laid open; 6) banner, ventral view; 7) keel-petal; 8) androecium; 9) pod.
