Leaves mostly 0.8-1 cm long, alternate, erect-spreading, oblong-lanceolate, acute or subacute, rounded at the base, concave and gland-warted above, rounded and with a prominent often, at first, pilose nerve beneath, with marginal and scattered glands. Flowers few, solitary at the ends of short leafy branchlets, sessile subtended by an ovate bract and 2 rotund deeply concave bracteoles. Sepals 2 mm long, widely ovate, rounded at the apex, very concave, ciliolate. Petals 8-9 mm long, oblanceolate, obtuse, slightly concave above, sparsely pubescent at the base, ciliolate, with many glands beneath near the nerve. Stamens with pubescent filaments. Staminodes 3 mm long, oblanceolate-oblong, obtuse, slightly concave above, pubescent and ciliate at the middle, with a round gland behind the apex. Disk embracing the lower part of the ovary, produced into a membranous tube readily splitting into toothed lobes. Ovary glabrous on the lower part, with 3 carpels bearing widely spathulate dorsally compressed erect-spreading processes with hairs on the margin and a few above. Style glabrous.
