“Morphological Specialization And Attachment Success In Two Twining Lianas”, 1982-07-01 (; backlinks):
The success rates of attachment of 2 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).
