Flowers: calyx appressed hairy; calyx tube about 2 mm high; calyx limb 1-1.5 mm long; calyx lobes imbricate, transversely elliptic, rounded or truncate at apex, ciliate, about 0.5 mm long; corolla white, trumpet-shaped, 6-8(-10) mm long, glabrous or slightly hairy or papillose, 5-lobed, the lobes spreading, obovate to spathulate, margin papillate or ciliate; corolla tube 2-3(-5) mm long; stamens monadelphous, 30-50 in number, about 5 mm long; staminal tube adnate to corolla tube, inside glabrous, free part 1-2.5 mm long, filaments flattened, abruptly narrowed at apex forming a short whip, papillose; disk cylindrical, 0.5-1 mm long, tomentose; style papillose, glabrous, 4-6(-8) mm long; ovary semi-inferior, 2-locular with 4 ovules in each locule. Fruits black, ellipsoidal, sparsely pilose, 6-9 mm long 3-5 mm in diameter, crowned by persistent calyx lobes, only 1 locule developed; stones obliquely ellipsoidal, smooth, with 2 lengthwise grooves, about 6 mm long 3 mm in diameter; mesocarp and endocarp thin; seeds 1, straight or slightly curved with straight embryo.

Distributed in the Ryukyus and Taiwan; in Taiwan, 400-2,600 m altitude in forest.
