Description
PLATE CXXVI Dalea carthagenensis (Jacqu.) Macbr. (pars): var. capitulata (Rydb.) Barneby and var. isthmicola Barneby. Both forms are endemic to s. Mexico, the former locally abundant in arid valleys at ± 800-1550 m from s. Michoacan to Puebla and centr. Oaxaca, the latter known only from the continental divide on Isthmus of Tehuantepec near 225 m alt.; they are low shrubs, flowering in fall and winter, the gland-tipped petals opening greenish or yellowish but early fading dull maroon purple, the plant thus seeming to bear flowers of two colors. The var. capitulata has almost smooth stems, leaves thinly pubescent, spikes all very short and dense, and relatively few leaflets, the var. isthmicola prominently warty stems, glabrous leaves, short but looser spikes, and many pairs of leaflets. — Stems × 1; the rest × 5. var. isthmicola: 1) flowering branchlet; la) leaflet, dorsal view; 2) bract, dorsal view; 3) flower + bract; 4) banner, ventral view; 5) wing; 6) keel; 7) fruiting calyx. var. capitulata: 8) flowering branchlets, that at left early in the season, with a terminal, pedunculate spike at anthesis and short-shoots developing in axils of still green primary cauline leaves, that at right later in the year, with short-shoots at anthesis but primary cauline leaves fallen; 9) flower + bract; 10) bract, ventral view.
