Description:
Species Description - Tree 4-25 m tall, branchlets terete, sometimes flattened at nodes, more or less lenticellate at maturity, lepidote, otherwise glabrous or glabrate. Leaves uniformly 3-foliolate, the leaflets elliptic or rhombic-elliptic to ovate, usually obtuse to acutish, sometimes short-acuminate, rounded to broadly cunete at base, 2-15 cm long, 1.2-10 cm wide, chartaceous to subcoriaceous, somewhat lepidote above and below, usually also puberulous along midvein above, below conspicuously pilose with simple trichomes in the axils of the secondary veins, sometimes also with simple trichomes scattered along the main veins or over the entire undersurface, drying more or less olive, usually lighter below; petiolules 0.1-3.5 cm long, petiole 1.5-9 cm long, lepidote, usually also slightly puberulous above. Inflorescence terminal, contracted and more or less fasciculate, with conspicuous subulate bracts and bracteoles 3-9 mm long, these drying grayish and lepidote with conspicuous whitish margins from the densely pilose cobwebby flexuous marginal trichomes. Flowers with the calyx campanulate, 2-3-labiate, 5-17 mm long, 4-8(-11) mm wide, drying black or dark brown, densely lepidote, sometimes also with scattered simple trichomes, always densely cobwebby pilose with flexuous matted trichomes on the lobes; corolla white to pink, tubular-infundibuliform, 2.5-7 cm long, 0.9-2 cm wide at mouth of tube, the tube 2-5 cm long, the lobes 0.6-2 cm long, glabrous outside except for a few scattered dark-drying plateshaped glands, the lobes ciliate, pubescent inside and in throat with long weak, flattened trichomes, pilose with glandular trichomes at level of stamen attachment; stamens didynamous, the anther thecae divaricate, 3 mm long; pistil 2-3 cm long, the ovary linear-cylindric, 3-5 mm long, ca. 1 mm wide, densely lepidote and with larger lepidote glands, some of the scales distinctly peltate-stalked; disk cupular, distinctly shallowly 5-lobed, 0.5-1 mm long, 1.2-2 mm wide. Fruit a slender capsule, 13-24 cm long, 0.5-0.7 cm wide, lepidote, drying grayish or brownish, the calyx persistent; seeds thin, bialate, 5-6 mm long, 2.5-3 cm wide, the hyaline wings sharply demarcated from the brownish body.

Discussion:
Uses. Sometimes cultivated as an ornamental; used for “tabua, taco, friso e ripas.” Characterized by the uniformly 3-foliolate leaves and (in flower) by the white to pink corolla and white cobwebby pubescence of the calyx lobes and bracteoles. The fruits are the narrowest of any sub-Amazonian Tabebuia, being equalled only by T. billbergii of northern South America.
