On Jan 11, 2005, Floridian from Lutz, FL (Zone 9b) wrote:

Angadenia berteroi is a vinelike, herbaceous perennial that grows from 8 to 30 inches tall, often branching towards the top. The leaves are opposite, linear oblong with slightly curled under margins. Bright yellow, trumpet shaped flowers appear all year, often singly or just a few at a time near the tips of the branches. The sap of this plant can cause severe eye irratation and mild skin rashes on sensitive people.

Its natural habitat is pinelands of southern Florida, The Bahamas, Cuba and Hispaniola.

Due to habitat destruction this plant is on the Florida Endangered Species list though it is still found to be locally common in some areas.
