Pentalinon luteum (Yellow Mandevilla Vine) Aka Wild Alamanda, Alamanda silvestre, Babeiro Amarillo, Hammock viper’s-tail, Licebush, Wild wist, Yellow mandevilla, and Allamanda dipladenia, is a vining plant native to islands of the Caribbean, Honduras, and the U.S. state of Florida.
Although Pentalinon is referred to a “Mandevilla”, it belongs to a different genus which is circumscribed to the West Indies, Central America, Mexico, and Florida (see USDA map below).
The genus “Pentalinum” refers in Latn to “five petaled”, and its epithet “luteum” means “yellow”.
Pentalinon luteum is an aggressive climber, but lacks tendrils. Seen from a distance, it can look like Allamanda, hence its popular name “wild Allamanda”, and it also belongs to the same Apocynaceae family.
Here is the house where it has climbed aggressively over a fence, and has reached the top of a power line.
