Hypanthia moderately stellulate-puberulent, conspicuously constricted abaxially the torus; calyx tube 0.5 mm long, moderately stellulate-puberulent within, the ovate-deltoid lobes 0.5-0.75 mm long, the exterior teeth 0.25 mm long, inserted on the rim-like calyx tube and not projecting beyond the lobes. Petals oblong to elliptic-oblong, distally papillate on both surfaces, 2-3.5 X 1-1.5 mm. Stamens somewhat unequal; anthers oblong-subulate, alternately 2-2.5 and 2.5-3 mm long, white, the larger with a dorsally inclined pore, the smaller with a truncate pore; connective not prolonged but dorso-basally dilated and ventrally bilobulate.
