This species is characterized by yellow flowers and large brightly colored bracts. Together they serve as attraction mechanisms for pollinators. The plant grows as a liana-like vine and can reach lengths in excess of 20 feet even indoors in a greenhouse.
This species is widely distributed in the Amazon rain forest and the Amazon foothills of the Andes; for this reason it is highly variable. You can see some of the variation in the bracts and flowers by clicking the links below:
