What are the morphological characteristics of this plant?

Clematis crassifolia has woody, climbing stems with opposite, trifoliate leaves characterized by thick, leathery leaflets that are elliptical to lanceolate in shape. The leaf margins are typically entire, while the texture is distinctly coriaceous compared to other species in the genus. Its flowers are relatively small and often possess a greenish or pale hue, emerging from the leaf axils. The plant utilizes twisting petioles to scramble over surrounding vegetation for support. Mature fruit consists of achenes that are equipped with long, persistent styles which facilitate wind dispersal.
