in Cabactulan, Aurigue, Pimentel, De Leon, Sahagun & Rodda, 2019.
A new species, Hoya pulchra Aurigue & Cabactulan (Apocynaceae), is described and illustrated. It is compared with the similar H. waymaniae, endemic to Borneo, from which it differs in lamina shape (lanceolate with a flat edge vs. elliptic-ovate with undulate edge) and the absence of bilobed apex in the outer corona lobe apex vs. a short raised bilobed apex.
