Pentalinon luteum (Yellow Mandevilla Vine)

800px-img_1070-copyPentalinon 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.

MandevillaAlthough 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”. 

MandevillaPentalinon 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.

  1. They’re such gorgeous flowers. I didn’t realize they came in multiple colors. There’s a city in Louisiana called Mandeville. I wondered if it was named for the same person. It wasn’t, although it’s possible there was some family connection: however slight.

    I wonder if I might have seen these, and assumed they were our bushier yellow bells (Tecoma stans). Both are beautiful.


    • The shape of Tecoma stans and yellow Mandevilla are similar, but the former is really a shrub or small tree with erect, weeping branches, the latter has very thin stems and begins to readily trail on any surface such as a fence. My confusion with this yellow Mandevilla was with the yellow Allamandas. They really look similar to me, specially when Allamanda is a young plant. Now I wonder if maybe the same has happened to you. You might have seen young Allamandas when they were really yellow Mandevillas, but I have no way of knowing.


    • Linda, you’re too good to say that. I was wrong again. This isn’t a “true” Mandevilla”, but they call it so because of a resemblance. They also call it “wild Allamanda” (but it isn’t an Allamanda either). The Allamanda is this one:

      In the U.S. it’s called Hammock viper’s-tail, Licebush, Wild allamanda, or Wild wist,

      Sorry for confusion and you’re nice to stick around when I occasionally get these wrong. This is right for sure though.


    • Yes, and believe me, no one will even attempt to remove them, because these yellow Mandevillas are regarded as highly desired ornamental plants. The reason they trailed out of control is because there is an empty lot next to the house with wired metal fences, so they had the space to grow and trail this way. I suppose the owners of the house could have pruned them.

    • Thank you Christy! Yes, this is quite nice because it’s not the usual “creeper” weedy plant, although I can like those too. It’s a very thin, soft-stemmed vine, unlike a woody liana. Very pleasant.


  2. What an impressive plant!!! Also, it’s very gorgeous.
    Maria, is there a plant that grows where I live, but doesn’t grow where you live? If I could find one, I’d take pictures for you.
    Trillium & Jack in the Pulpit are very hard to find, but those are the only 2 I can think of that maybe don’t grow where you are.
