Characteristics

A small deciduous tree or shrub, up to 6 m. tall.. Leaves simple, with blades elliptic or oblong-elliptic, rarely obovate-elliptic, apex subacute to rounded or even slightly emarginate, base rounded to shortly cuneate, 3.5–10.5 cm. long, 2–6.5 cm. broad, subcoriaceous, rugose-reticulate, indumentum very variable, petioles 5–7 mm. long.. Inflorescences axillary or terminal to longer or shorter branches, 2–9-flowered, the branches and the calyx densely and shortly white-tomentose.. Corollas white or yellow-green with brown hairs, tube 1.1–1.8 cm. long.. Fruits pear-shaped, 6 cm. long, 3 cm. in broadest diameter, with thick woody valves.. Seeds (including the unilateral membranaceous wing) flattened, narrowly elongate-ovate, 5 cm. long, 1.5 cm. broad.
More
Corolla cream–coloured or greenish; tube 13–21 mm. long, pilose inside near the base; lobes (5) 6 (7), 5–8 (11) x 3–4– (10) mm., unevenly obovate with apex obtuse or emarginate, each with a patch of dense maroon to dark brown dilated hairs extending from the corolla mouth almost to the petal margin.
Leaf lamina 4·5–14 x 2·5–7·5 cm., elliptic, oblong–elliptic or ovate, the apex rounded, acute, acuminate or apiculate, the base acute; leaves occasionally glabrous but usually upper surface at first pubescent, later glabrescent and lower surface softly hispid especially on main veins.
Fruit a woody bivalved pear–shaped capsule 4–6 cm. long, straw–coloured, often warty, splitting open at maturity; locules 2, each containing 2 winged seeds up to 5 cm. long and 2 under–developed seeds which remain united to form a woody compressed–elliptic structure.
Anthers 2–3 mm. long, on filaments up to 1 mm. long; flowers dimorphic: stamens inserted near the top of the corolla so that the anthers either reach the corolla mouth or are 1·5–3 mm. distant from it.
Inflorescence a terminal few– to several–flowered cyme 3–6 cm. long; bracts and bracteoles inconspicuous and soon deciduous; axes glabrous to tomentose; pedicels 2–16 mm. long.
Leaf venation, including the fine tertiary reticulation, clearly visible; main nerves impressed on upper surface, prominent below, reticulation raised on both surfaces.
Calyx 2–4 mm. long, glabrous or puberulous, truncate or irregularly 4–5–lobed at apex.
Leaves simple; petioles 5–15 mm. long, without articulation, usually softly hispid.
Shrub or bushy tree 2–10 m. tall, the trunk with rough grey flaking bark.
Style correspondingly either half as long as corolla tube or exserted.
Young shoots whitish–pilose or less often glabrous.
