Clematis gouriana is a large, woody perennial climber belonging to the family Ranunculaceae. It features long, grooved stems that can climb high into the canopy of trees, often reaching several meters in length. The leaves are pinnate or sometimes bipinnate, composed of ovate to oblong-acuminate leaflets with a glossy surface. The plant produces small, fragrant flowers about 1 to 1.5 cm across, which are greenish-white and lack true petals; instead, they have four greenish sepals covered with soft hairs. Flowering typically occurs from late summer through winter.
The fruits of Clematis gouriana are compressed achenes with persistent, feathery styles that aid in wind dispersal. This climber is known for its vigorous growth and ability to cover large areas, often found sprawling over shrubs and trees in its natural habitat. Its delicate flowers and lush foliage make it an attractive species both in the wild and for ornamental purposes.
Habitat
Clematis gouriana is native to tropical and subtropical regions across the Indian subcontinent, Southeast Asia, and parts of southern China. It commonly grows in forest edges, dry deciduous to evergreen forests, and open woodlands, climbing over shrubs and trees. It thrives at elevations ranging from sea level up to 1,500 meters, particularly in the Western and Eastern Ghats, the Himalayas, and other hilly regions.
