| Hoya verticillata | |
Hoya verticillata, commonly known as claret hoya, is a species of climber in the oleander and frangipani family Apocynaceae. It is found from India to southern China, through southeast Asia to Indonesia and the Phillipines.[2] Called "Palu-lobboi" in Bangladesh.[3]
Description
This plant is a root climber but may also twine around objects, and all parts exude a white sap when broken. Leaves are arranged in opposite pairs and have 3 or 5 veins. Flowers are produced in racemes but appear to be in umbels.
Taxonomy
In Australia, there are specimens known as Hoya pottsii,[4][1][5] which Plants of the World Online (POWO) considers to be a synonym of H. verticillata, though POWO does not list Australia as part of the range of H. verticillata.[2] Those Australian plants had been known as Hoya nicholsoniae F.Muell. before being renamed as H. pottsii.[6] Mark Randal considered that the plants identified as Australian H. pottsii should still be regarded as H. nicholsoniae,[7] a species that POWO does accept as native to Queensland, Australia.[8]

As of August 2026, POWO accepts the following three varieties:[2]
