Two new Hoya R.Br. species from Borneo are described and illustrated. The first, Hoyaruthiae Rodda was collected in Sabah on Bukit Baturong, a limestone outcrop. It is one of the few species in the genus to have clear exudate. It is compared with the morphologically related Hoyauncinata Teijsm. and Binn. The other, Hoyabakoensis Rodda, was collected in the kerangas forests of Bako National Park. It belongs to HoyasectionAcanthostemma (Bl.) Kloppenb., a section with numerous members in the Philippines but under-represented in Borneo.
