Allomarkgrafia plumeriiflora

Native to Honduras, Nicaragua, Costa Rica, Panama and Colombia, this climbing plant grows in wet tropical forests. It produces abundant white latex and can reach the forest canopy, although it also occurs along forest edges. Its flowers range from white and cream to pale yellow or greenish cream, with a tubular base opening into a broad funnel. In Costa Rica, it grows from near sea level to about 3,300 feet.
