Oak grain in the twigs. Adult leaves simple, leaf blades about 7.5-14 x 2.5-7 cm. Petioles about 3-8 cm long. Midrib raised on the upper surface of the leaf blade. Small oil dots visible with a lens. Terminal buds and young shoots densely clothed in rusty brown hairs.
Inflorescence about as long as the leaves, each umbel containing up to 20 flowers but usually about 16. Peduncles about 5.5-9.5 cm long. Pedicels about 10-17 mm long. Tepals about 20-30 mm long, ferruginous-pubescent outside, glabrous on the inside. Stamens sessile, anthers about 2-2.5 mm long. Hypogynous gland +/- horseshoe-shaped, about 4 mm long. Ovary stalked, ferruginous-pubescent, about 10-13 mm long, ovules about 7-11. Style about 15-18 mm long, glabrous. Pollen presenter a broad oblique disk.
Follicles about 10-13 x 1.4-2.2 cm, but better material is needed. Seed features not known.
Cotyledons broadly obovate to almost rectangular, about 30-35 x 20-30 mm. At the tenth leaf stage: leaf blade usually 3-lobed, midrib raised on the upper surface of the leaf blade; lateral veins forming loops well inside the blade margin; terminal bud clothed in pink or rusty red, prostrate hairs.
