Description
PLATE LXIV Dalea frutescens Gray and D. hospes (Rose) Bullock are both glabrous shrubs, and alike in the short-toothed calyx which is shiny and (almost always) hairless without but densely silky around the mouth. The low, intricately branched D. frutescens only rarely attains a stature of 1 m; the flower is sessile and the petals are bicolored, the banner opening white in contrast to the rose-purple wings and keel. This pretty and floriferous dalea is common over much of mountainous Coahuila and of the Edwards Plateau in Texas, extending north to the Arbuckle Mountains in Oklahoma, west through trans-Pecos to the White Mountains in New Mexico and to eastern Chihuahua, and south just into Nuevo Leon. The much taller D. hospes reaches when fully grown a stature of 1.5-3 m, forming slender, erect, even arborescent shrubs commonly with a single trunk branching into a thin crown of pliant branchlets. Its flower is pedicelled, and the petals open pale greenish-yellow, at least the banner and sometimes all fading brown or reddish. Strongly calciphile, D. hospes is endemic to the northern Sierra Madre Oriental; it is common in Nuevo Leon but extends only shortly north and east into Coahuila and Tamaulipas.— Inflorescences × 1; the rest × 5. D. frutescens: 1) flowering branchlet; 2) stipules; 3) leaflets; 4) bract, dorsal view; 5) flower + bract; 6) banner, ventral view; 7) wing; 8) keel; 9) androecium; 10) pod. D. hospes: 1) flowering branchlet; 2) stipules; 3) leaflets; 4) flower + bract; 5) banner, ventral view; 6) keel; 7) androecium; 8) pod.
