Phellocalyx Bridson

Shrub or small tree; branches pubescent when young. Leaves opposite, petiolate, membranous, restricted to new growth at apex of stems; domatia present as white hairy tufts in the nerve-axils; stipules interpetiolar, ovate-triangular, with colleters and silky hairs inside. Flowers precocious, hermaphrodite, solitary, terminal on short lateral branches (but may be exceeded by the development of an axillary branch), sessile, large. Calyx 6–8-ribbed, covered with very short fleshy hairs when young, which soon erode to reveal a rather flaky corky underlayer; tube campanulate; limb entire in bud, acuminate, rupturing into 2–3 lobes at anthesis, densely covered with silky hairs with large interspersed colleters inside. Corolla-tube short in proportion to the lobes, cylindrical to funnel-shaped; lobes 8–11, narrowly oblong, spreading, overlapping to the right in bud (as seen from outside). Anthers 8–11, sessile, attached near the base, inserted at throat, exserted, ± two-thirds the length of the corolla-lobes, linear, shortly acuminate; pollen-grains simple. Ovary 4-locular (or ? incompletely so); septa thinly membranous, adhering to the placentas; placentas 4, elongate, fleshy, attached at the apex to the style-base; ovules numerous, impressed on the placentas; disc annular; style slightly swollen, glabrous; stigmatic club exserted, cylindrical, 2-winged, bifid at apex with each lobe emarginate. Fruit large, globular, smooth, 1-locular; calyx-limb caducous; pericarp thick. Seeds numerous, embedded in pulpy placental tissue, sublenticular; testa very thin, finely rugulose; endosperm entire, horny; embryo straight.
