Description
PLATE LXXIII Dalea caeciliae Harms and D. insignis Hemsl. resemble each other and D. mutabilis (Plate LXXIV) in most structural details of the flower and pod, but each in its own way is uniquely modified. Both are rare and local species, known each from two or three scattered localities in Puebla and Oaxaca, where they are confined, so far as known, to limestone bedrock. The erect, suffrutescent D. caeciliae, immediately recognized by its densely black-warted stems, is variably but thinly pilose; the flowers are shortly pedicelled and bicolored, the banner opening white and fading purplish in contrast to epistemonous petals that are tipped or suffused with dark but vivid blue. The almost glabrous D. insignis is a coarse, amply leafy annual herb up to 8 dm tall. The development of the stipules into foliaceous fins and the bracts into immense, papery-membranous, veiny boats that enclose a small glabrous calyx, has no counterpart in Dalea. Inflorescences × 1; the rest × 5, unless where mentioned. D. caeciliae: 1) summit of flowering stem; 2) part of stem, showing peg-shaped warts, × 10; 3) flower + bracts; 4) banner, ventral view; 5) androecium; 6) pod. D. insignis: 1) top of stem; 2) leaflet, dorsal view × 2; 3) bract, profile view; 4) flower; 5) banner, ventral view; 6) androecium; 7) pod.
