Explanation

The pedicels or floral stalks of Artabotrys are modified into stiff curved thorns or hooks for helping in climbing. Hook is formed by peduncle in uncaria gambir. In Antigonon the flower occurs in bunches in the axils of scale, leaves on the floral shoot. The upper floral buds develop into tendrils instead of forming flowers.
