Parthenocissus himalayana

A vigorous deciduous climber, with semi-woody, glabrous young stems; the tendrils terminated by clinging disks. Leaves composed of three leaflets, each shortly stalked and borne at the end of a slender, common stalk 2 to 5 in. long. Central leaflet ovate, oval, or obovate; the side ones very obliquely ovate (two or three times as much blade on one side of the midrib as on the other), and often somewhat heart-shaped at the base on one side only. They are all abruptly tapered at the apex, toothed, dark green and glabrous above, paler, slightly glaucous beneath, with a few short hairs on the midrib only; 2 to 6 in. long, 11⁄4 to 4 in. wide. Fruits globose, 1⁄4 in. wide, in loose clusters several times forked.

Native of the Himalaya up to 11,000 ft. It is a rather tender species, and only thrives well on a wall. Its leaves change to rich red in autumn.

Synonyms
Vitis semicordata Wall.
V. himalayana var. semicordata (Wall.) M. A. Lawson

This is perhaps not specifically distinct from P. himalayana, but it has smaller leaves and its young shoots and the undersurface of the leaves are bristly. It is perhaps a form from higher altitudes.
