Hoya devogelii(Apocynaceae Asclepiadoideae), a new species from kerangas heath forests in Sarawak, Borneo

Abstract

Summary 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 flowered species of Hoya from Borneo are discussed.
