Growth Form: Shrubs or small trees up to 5 m tall with grayish, rounded crown.

Stems: Trunk 5–8 cm in diameter, smooth, grayish bark and prominent petiole scars on young branches, glabrate to stellate puberulent.

Roots:

Leaves: Leaves simple. Alternate. Blades blades broadly ovate, 4–10 cm long. Base shallowly cordate. Upper surfaces sparsely pubescent lower surfaces more densely so but without conspicuous tufting in the vein axils. Margins broadly and sometimes irregularly dentate. Petioles 1.5-5 cm long. Stipules present 1-2 mm long.

Flowers: Flowers solitary, erect, borne near the ends of branches, pedicels 1–3 cm long; involucral bracts 7–9, 12–16 mm long, connate ca. ⅓ their length, limbs narrowly triangular, 1.5– 2.3 mm wide at base. Flowers bisexual (perfect). Calyx tubular, 1.3–2 cm long, 5-lobed but often opening by 2-3 clefts, lobes triangular, 0.3–0.5 cm long, valvate in bud, persistent in fruit or circumscissilly dehiscent toward base before capsule maturity. Corolla usually zygomorphic, tubular to rotate or reflexed, corolla of 5 petals, obovate, bright green, becoming dull reddish, 3–4 cm long, curved and narrowly convolute with the 2 lower petals shorter and usually spreading or reflexed apically, densely stellate pubescent on lower surface and often on upper surface near apex, usually conspicuously veined. Stamens 5 to numerous, monadelphous, forming a staminal column, exserted or exposed apically by the spreading lower petals; antheriferous in upper ⅓–½ below the 5–dentate apex; anthers monothecal. Pollen globose, echinate. Ovary superior, placentation axile, 5-celled; ovules (2)3 per cell; style exceeding the staminal column, branches 5, erect; stigmas terminal, capitate or discoid.

Fruit: Capsules chartaceous; ovoid; ca.2.5 cm long; 1.5 cm in diameter; mesocarp weakly developed and usually adnate to exocarp; endocarp segments 5; boat-like. Seeds 2 per cell; reniform; ca. 5 mm long; sparsely yellowish brown pubescent; with or without endosperm.
