Description

Key Characters:

Growth Form: Shrub, 2.4 m tall.

Stems: Stems branched, glabrous.

Roots:

Leaves: Leaves simple. Alternate. Blades 11–20 cm long, 1.4–2.3 cm wide, narrowly elliptic or narrowly oblong. Apex acuminate. Base cuneate. Upper surfaces dark green, glabrous; abaxial surface light green, glabrous. Margins callose–serrulate, often revolute. Petioles 2.5-6.8 cm long, glabrous. Stipules absent.

Flowers: Flowers in inflorescences 5–10–flowered, axillary; peduncle 25-28 mm long, glabrous; rachis 4–7 mm long, glabrous; bracts deciduous; pedicels 6–8 mm long; hypanthium 3–4 mm long, 2–3 mm diam., broadly obovoid, glabrous. Flowers bisexual (perfect). Calyx 5-lobed, lobes 0.5 mm long, deltate or shallowly deltate, distinct or rarely connate, the apex acute, tube adnate to ovary. Corolla zygomatic, 22–28 mm long, white faintly tinged with purple, glabrous; tube 13 mm long, 2 mm diam. at middle, gently curved, dorsally cleft for about half its length; dorsal lobes 15 mm long, 1.7 mm wide, linear, the apex acuminate; ventral lobes 11 mm long, 2 mm wide, linear, basally connate for 6 mm, the apex acuminate. Stamens 5, alternate with corolla lobes, connate; staminal column exserted; filaments distinct or connate above, attached to the epigynous nectary disk or to base of corolla, rarely adnate to corolla tube; filament tube 23 mm long, glabrous; anther tube 2 mm diam., the surfaces glabrous; dorsal anthers 6 mm long; ventral anthers 4.8 mm long, with tufts of hairs at apex, dithecal, opening by longitudinal slits, coherent but separating after anthesis or connate and forming a tube into which pollen is shed. Ovary inferior, 2-celled; ovule placentation axile; stigma 2-lobed, wet or dry, appressed and nonreceptive as the style grows through the anther tube, pushing out the pollen, after which the stigmas spread apart and become receptive.
