Description
PLATE LXXXIX Dalea elegans Gill, is dispersed along the east slope and piedmont of the Andes from the department of Tarija in extreme southern Bolivia south in Argentina to Salta and further, through Sierra Grande de Cordoba to Sierra San Luis, where it attains the southern limit of the genus in lat. 33° S. Among Andean daleas it is remarkable chiefly for the many pairs of leaflets, which vary however greatly in size and texture. The xerophytic var. elegans, a low, scarcely suffruticose herb with mostly monocephalous stems up to 5 dm long, has small, crowded, fleshy leaflets; the banner is partly white, the inner petals amethyst-purple. Its range extends south from Salta and below 2000 m along the Andean foothills and the detached ranges east of the Andes proper. The tall, weakly frutescent var. onobrychioides, with several-headed stems, reaching 6-12 dm in height, has expanded leaflets of thinner texture; the flower is all blue, except for a small white eye in the banner. The var. onobrychioides is strictly Andean, ranging north from Salta, mostly above 2000 m, through Jujuy into Bolivia. Inflorescences × 1; the rest × 5. var. elegans: 1) top of stem; 2) stipules; 3) leaflets; 4) flower + bract; 5) bract, dorsal view; 6) calyx, laid open; 7) banner, ventral view; 8) wing; 9) pod. var. onobrychioides: 10) summit branchlet; 11) leaflet, dorsal view; 12) flower + bract; 13) bract, half-profile; 14) banner; 15) wing; 16) keel; 17) androecium.
