Description
PLATE CXXV Dalea carthagenensis (Jacqu.) Macbr. (pars): the races found in South America n. of the equator, in Central America n. to Chiapas, in the Antilles, and in s. Florida. Slender, often weedy shrubs of low elevations, flowering in fall and winter, with small greenish-creamy flowers early fading dull purple or brownish, all are more or less seasonally dimorphic, the relatively ample primary foliage and pedunculate spikes of the young, vigorous growth giving way, in the dry season, to short-shoots clothed in simpler, shorter leaves and smaller, subsessile spikes. The vars. carthagenensis, floridana (Rydb.) Barneby, and portoricana Barneby may have stems and leaves either glabrous or variably pilosulous; the first, with relatively few (± 5-8) pairs of leaflets and relatively large-keeled flower, is common on the Caribbean slope in n. Colombia and Venezuela, extending thence feebly inland and n. disjunctly to Hispaniola and Virgin Islands; vat. floridana, with the same flower but up to 8-11 pairs of leaflets, and var. portoricana, with leaflets of var. carthagenensis but diminutive keel-petals, are endemic to peninsular Florida and Porto Rico respectively. The var. barbata (Oerst.) Barneby, like var. carthagenensis in leaf and flower, is always pilosulous throughout, often densely so, and the small calyx-glands are masked by a dense coat of fine spiral hairs. The range of var. barbata extends through Central America from Chiapas into Panama and interruptedly to the n. Colombian Andes, where it fades into var. carthagenensis. Between s. Guatemala and Nicaragua it is sympatric with the related and similar D. scandens var. vulneraria (Plate CXXIX), distinguished by a calyx-tube glabrous and gross-glandular surmounted by pilosulous, apically hooked teeth.— Branch and detached (primary cauline) leaves × 1; leaflets × 3; the rest × 5. var. carthagenensis: 1) flowering branch; 2) leaflets, pilosulous and glabrous; 3) bract, ventral view; 4) flower; 5) banner, profile and ventral views; 6) wing; 7) keel; 8) androecium; 9) pod. var. barbata: 10) primary leaf + flower, var. portoricana: 11) do. var. floridana: 12) do.
