Himalayan clematis is a vigorous climber from the Himalayas, with delicate nodding pale-yellow bell-shaped flowers with recurved sepals. The flowers are somewhat hidden behind the rather big leaves. This Clematis is distinguished by its leaf-stalks fused at base, forming large flat disks. Leaves are pinnate - leaflets oval-lancelike to heart-shaped, sharply irregularly toothed, hairless. The bell-shaped flowers occur in branched axillary clusters, and have pale yellow anthers. Flowers are mildly sweet scented. Himalayan Clematis is found in the Himalayas, from Pakistan to China, at altitudes of 1800-3300 m.
