Shrubs, 2-4 m. Branchlets grooved, densely stellate pilose and puberulent, glabrescent. Petiole 2.5-5.5 cm, stellate pilose, glabrescent; leaf blade simple, oblanceolate, 11-27 × 3.5-8 cm, papery or rarely thinly leathery, both surfaces stellate pilose, when young, glabrescent, lateral veins 14-16 on each side of midrib, base shallowly cordate, rarely cuneate, apex acuminate.

Calyx purple, divided nearly to base, exterior stellate pilose, interior glabrous, lobes lanceolate, 12-14 × 3.5-4.2 mm, incurved with coherent tips, margin ciliate.
Male flowers: androgynophore curved, 3.5-4 mm glabrous. Female flowers: ovary globose, white stellate pilose; style curved, white stellate pilose.

產地生境
● Forests; ca. 1400 m. S Yunnan (Simao). ● 森林; 約1400米。雲南南部(思茅Simao)。
More detailed study could show that Sterculia simaoensis is better included within S. henryi. It is differentiated by the subcordate base of the leaf blade, the relatively shorter bracteoles, only ca. 1/2 as long as the pedicels, and by the purplish, not yellow-brown, indumentum of the inflorescence.
更詳細的研究能顯示Sterculia simaoensis 最好置於 S. henryi內。它差別在於,葉片的近心形的基部,相對短的小苞片,僅長約花梗的1/2,和具紫色的花序毛,而非黃棕色的。
