Description
PLATE XLI Dalea elata H. & A., a polymorphic Mexican species dispersed in thorn-forest, grassland, and open oak forest, mostly below 1000 m, along the piedmont of the Sierra Madre from southern Sonora to Jalisco, thence through the valleys of Rio Grande de Santiago and Rio Balsas to Morelos, and along Sierra Madre del Sur to Guerrero, with outlying stations in Chiapas and on the Gulf slope in Veracruz. The plants can flower preciously when only 1-4 dm tall, and then bear only juvenile foliage, with about 3-7 pairs of leaflets to the leaf. In favorable sites they become perennial, eventually suffruticose or even genuinely shrubby and up to two or even three meters tall, the main cauline leaves then composed of up to twelve pairs of leaflets giving way, however, in the ample but irregular panicle, to leaves of a shorter, simpler type. The foliage varies from almost glabrous to softly pilosulous, and the calyx-tube may be densely pilose throughout, pilose only at base, or glabrous and lustrous. The inconspicuous whitish flowers, produced in flexuous, catkin-like spikes mostly during the dry winter season, but sometimes also in spring or summer, are of fleeting duration, the small inner petals disjointing from the column as this expands in full anthesis.—Habit × 1; the rest × 5. 1) branch of panicle + one main cauline leaf; 2) stipules; 3) glabrous leaflets; 4) pilosulous leaflet; 5) bract, ventral view; 6) flower, showing the inner petals detached; 7) glabrate calyx; 8) banner, ventral and profile views; 9) androecium; 10) pod.
