Pentalinon luteum

Wild allamanda
Hammock viperstail

Florida native

Monroe Co. FL 05/20/09
This vine of south Florida pinelands, mangroves and coastal hammocks is also found in the West Indies.
The 5 cm (2 in.) wide trumpet shaped flowers usually bloom one at a time from April through September and can be axillary or terminal. Pentalinon luteum flowers have narrowly lanceolate calyx lobes and appendages on the tips of the anters that help differentiate this species from the similar Angadenia berteri. The glossy, revolute leaves are opposite, 2.5 - 7.6 cm (1 - 3 in.) long and 1.2 - 2.5 cm (1/2 - 1 in) wide. The vine grows up to about 3 meters (10 ft.) in length.
Like many members of the dogbane family, the leaves and flowers of this plant are poisonous and the sap can be an irritant to the eyes and skin.
