Description

Liana or shrub; young branches tomentose to tomentellous, becoming glabrous with age. Stipules lanceolate, 2-4 mm long, subpersistent or caducous, densely tomentose, margin entire. Petiole 2-35 mm long, densely tomentose; blade thickly coriaceous, oblong to ovate-elliptic, 6-32 x 3.5-21 cm, most frequently acute but varying from rounded to acuminate at apex, subcuneate, rounded or subcordate at base, plane not bullate, or weakly bullate only above, densely hirsute beneath; midrib plane and pubescent above, 7-13 pairs of secondary veins, slightly impressed above. Inflorescence a terminal, axillary or petiolar corymbose panicle, 1.5-8 cm long, rachis and branches tomentose. Flowers hermaphrodite; pedicels 0.5-2 mm long; bracts and bracteoles triangular, 0.5-3 mm long, persistent, tomentose; calyx 3-3.5 mm long, densely ferrugineous-tomentose on exterior, lobes equal; petals of 5 equal lobes, bifid and weakly cucullate at apex, creamy white, glabrous; fertile stamens 5, alternating with and equalling petal lobes; disk of 5 separate bifid glands, united at base; ovary lanate on exterior, style lanate at base, glabrous above, apex shortly 3-fid. Fruit 1-2-locular, epicarp densely velutinous tomentose, mesocarp thin, endocarp very thin, hard, bony, glabrous within.

Notes

The type of this species is the specimen in the Vahl herbarium at Copenhagen which does not bear a collector's name. It is probably a duplicate of a Richard collection with a Symphyllanthus manuscript name which is at Paris and Geneva.
