Description
Species Description - Glabrous, excepting a very minute puberulence on the flowers. Branchlets very slender, reddish-brown, finely nerved. Petioles to 4 cm. long in my specimen, slender, narrowly grooved, the rachis to 10 cm. Leaflets 1 to 3 pairs, the petiolules 5 to 8 mm. long, the terminal leaflets to 2 dm. long, 7 cm. wide, oval to obovate, very abruptly contracted into a short, obtuse acumination, thin, pale-green, the slender venation slightly prominent beneath, the secondaries 8 or 9 on each side, very slender, widely spreading, lightly falcate at the summit. Lower leaflets similar, but much smaller. Panicles branched from the base or on long slender peduncles, very lax and sparsely flowered. Flowers unopened in my specimen. Mature buds on pedicels 2 mm. long, which are sharply angled, with or without minute bractlets at or above the base. Calyx broadly campanulate, 2 to 3 mm. wide, the margin irregularly and very shallowly lobed, the calyx deep purple-brown, thick, grayish-puberulent. Corolla-bud about 7 mm. long, obovoid with rounded summit. Stamen-tube 6 mm. long, almost equaling the petals, the margin very shallowly 10-crenate. Anthers sessile, 1.5 mm. long, reaching the summit of the tube. Ovary 3 mm. long, nearly cylindric, 5-angled, the stout style a little shorter, the stigma more than 1 mm. broad.
