Type of flowering specimen 9018, A. D. E. Elmer, Luc- 
ban, Province of Tayabas, Luzon, May, 1907. It was first 
discovered in a wooded ravine at the base of Mount Ban- 
ahao at 775 meter altitude, where it climbed large trees and 
formed tangled masses over their tops. It was again ob- 
served in a small gulch near Lucban at a lower altitude, 
sprawling over the thickets.
