Description

Key Characters:

Growth Form: Branched shrubs 1.5–2 m tall.

Stems: Stems smooth.

Roots:

Leaves: Leaves simple. Alternate. Blades ovate to broadly elliptic, blades 10–22 cm long, 6–14 cm wide (across the lobes). Apex acute to acuminate. Base obtuse to truncate. Margins irregularly lobed or cleft. Petioles 4–12 cm long. Stipules absent.

Flowers: Flowers in inflorescences 6–8–flowered in axillary racemes, peduncles 30–70 mm long, pedicels 12–15 mm long; hypanthium ovoid, 4–6 mm long, 3–4 mm wide. Flowers bisexual (perfect). Calyx 5-lobed, lobes triangular, 2–3 mm long, ca. 1 mm wide, distinct or rarely connate, apex acuminate, tube adnate to ovary. Corolla zygomorphic, white tinged or striped with pale lilac, 30–38 mm long, 3–4 mm wide, glabrous, the tube slightly curved, dorsally cleft to about the middle, the lobes connate, spreading, ¾ as long to as long as the tube. Stamens 5, alternate with corolla lobes, connate, staminal column glabrous; anthers glabrous, the lower 2 with apical tufts of white hairs, dithecal, opening by longitudinal slits, coherent but separating after anthesis or connate and forming a tube into which pollen is shed; filaments distinct or connate above, attached to the epigynous nectary disk or to base of corolla, rarely adnate to corolla tube. 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.
