The success rates of attachment of two twining lianas, Ipomoea phillomega (Vell.) House (Convolvulaceae) and Marsdenia laxiflora Donn. Sm. (Asclepiadaceae), were compared. Ipomoea phillomega , a liana with relatively unspecialized shoot architecture, was found to have a lower success rate than M. laxiflora , a liana with specialized photosynthetic and twining shoots. The relatively lower success rate of I. phillomega is due to its reduced ability to remain attached to very thin supports (<7 mm in diameter).
