Liana is a description of a group of tropical woody plants that use trees and other vegetation to reach sunlight from the forest floor. They grow up, through and over supporting vegetation binding tropical biodiversity together giving strength through tropical storms to weaker elements of the vegetation and facilitating access corridors through forests for wildlife by joining the canopy together.
The flower develops as a greenish yellow elongating bud with prominent veining. At maturity within the chalice shaped flower are dark striations that run to the depths of the corolla tube. Copious amounts of powdery white pollen drop onto this from the anthers.
