Hoya medinillifolia (Apocynaceae Asclepiadoideae), Una nuova specie proveniente dalle foreste di bassa quota del Sarawak, Borneo -La nuova specie, Hoya medinillifolia Rodda & Simonsson viene qui descrita ed illustrata. Presenta similarità con la ampiamente diffusa Hoya multiflora Bl. e la specie endemica delle Filippine Hoya platycaulis Simonsson & Rodda a causa dell'abitus eretto, le foglie lanceolate coriacee ed i fusti giovanili appiattiti. Può essere facilmente differenziata da queste in quanto presenta lobi della corona cuoriformi e differente venatura fogliare.

A new species from kerangas heath forest of Brunei, Borneo, Hoya wongii, is here described and illustrated. This species differs from the previously described species of Hoya in having a corona with inflated outer processes and laterally compressed and erect inner processes, ending in two bidentate membranaceous appendages. The corona is inserted above a pale yellow campanulate corolla. We discuss morphological affinities between the new species and other campanulate flowered species of Hoya.
