The new species, Hoya medinillifolia Rodda and Simonsson is hereby described and illustrated. It is similar to the widespread Hoya multiflora Bl. and to the Philippine endemic Hoya platycaulis Simonsson & Rodda due to the erect growth habit, the lanceolate, coriaceous leaves and the juvenile flattened stems. It can be easily separated from these because of its heart shaped corona lobes and the different leaf venation. Source

The new species Hoya devogelii Rodda & Simonsson with campanulate corollas from kerangas montane forest of Sarawak, Borneo is here described and illustrated. This species differs from any previously described species of Hoya in the very pubescent corolla and the staminal corona with a very developed process forming a ring around the base of the corona lobes. Morphological affinities between H. devogelii and other campanulate fl owered species of Hoya from Borneo are discussed. Source
