Stem: creeping or climbing to a height of 30 m with adventitious roots. Evergreen foliage, dark green, glossy, lighter underneath, glabrous, leathery, lanceolate, oval, to klapowanych (flaps odd, usually 3, triangular), u heart-shaped base of the wedge, the top slightly pointed or blunt. Flowers: bisexual, small, 5-fold, meeting within the fond owate panicles. Flower stalks (length 7–12 mm) and Flowering hairy. Chalice entire edges, retained. Petals yellow crown.

The plant blooms from October to April.

Plant toxic, all parts are poisonous because they contain saponins (e.g. hederynę), which are irritating to the skin, and conjunctiva of eyes, and after ingestion induce gastrointestinal nervous system, disturbances. Can occur hemolysis and erythrocytes.

It occurs mostly in moist soil in shade, at the height of 1000–3000 m as climbs over rocks and tree trunks by adventitious roots, rarely used as a ground cover or decorative climber in gardens and parks. Resistance to frost apparently large (up to 8 zones USDA).

There are two varieties or subspecies:[1]

Hedera nepalensis var. nepalensis
''Hedera nepalensis K. Koch var. Sinensis (Tobler) Rehder - occurs in the China.
