Description
PLATE LIII Dalea searlsiae (Gray) Barneby and D. scariosa Watson, prairie-clovers of arid Southwestern United States, with thick-textured, glaucescent foliage and moderately dense spikes of rose-purple flowers. The virgate stems of D. searlsiae, which ranges over the w. half of the Great Basin into the n. and e. Mohave Desert and n.-w. Arizona, are erect-ascending and simple or few-branched; the leaves vary from glabrous to pilosulous, and the flowers mature in late spring and early summer, seldom later than mid-July. The much rarer D. scariosa, confined to bluffs of the Rio Grande valley in n.-centr. New Mexico, flowers in late summer, from August onward; the foliage and outer surface of the calyx are always glabrous; and the stems are diffusely trailing and freely branched to form fan-shaped sprays of many spikes. A character common to both is a calyx deeply recessed behind the banner and in fruit constricted just above the base. — Branchlets × 1; the rest × 5. D. searlsiae: 1) tip of flowering stem; 2) leaf from middle of stem (the villosulous form); 3) stipules; 4) bract; 5) flower; 6) petals, the banner in ventral view; 7) androecium + gynoecium at late anthesis; 8) fruiting calyx; 9) pod. D. scariosa: 1) summit branchlet, in fruit; 2) stipules; 3) leaflets; 4) bract, profile and dorsal views; 5) flower; 6) banner, ventral view; 7) wing-petal; 8) keel-petal; 9) androecium; 10) fruiting calyx; 11) pod.
