Habitus
Inflorescences and young leaves

Henry's maple is a small, broad-crowned tree or large shrub up to 10 meters high . The bark of the branches is initially green and hairy and later olive green and bare. The leaves are divided into a petiole and a leaf blade. The petiole is 5 to 10 inches long. The leaf blade is threefold. The leaflets are stalked, 5 to 10 centimeters long, elliptical, long, pointed with a wedge-shaped base. The leaf margin is serrated away or whole. Both sides of the leaf are green, the nerves on the underside of the leaf are hairy. In autumn the leaves turn red.

Acer henryi is dioeciously segregated ( diocesan ). The flowers are arranged in slender, hairy racemose inflorescences and appear before the leaves. The fruits grow in 10 to 15 centimeters long, hanging clusters. The individual fruits are 2 centimeters long, initially red in color and have an acute-angled spread wing. The flowering time is in April and it is fruitful in September.

The distribution area is in the Chinese provinces of Anhui , Gansu , Guizhou , Henan , Hubei , Hunan , Jiangsu , Shaanxi , Shanxi , Sichuan and Zhejiang . There it grows in species-rich mixed forests, at altitudes of 500 to 1500 meters. It thrives on fresh to moist, acidic to neutral, sandy-humic or loamy-humic soils in sunny to light-shaded locations. These are demanding, warmth-loving and mostly frost-hardy trees.
