A new Hoya subspecies from Borneo and Sumatra, Hoya fauziana ssp. angulata is described and illustrated. Both subspecies of Hoya fauziana have long lanceolate leaves, pubescent corollas and prominent ovoid corona lobes. They can be separated by the orientation of the pedicels (straight in H. fauziana ssp. fauziana and angled in H. fauziana ssp. angulata) and the type and position of pubescence of the corolla (tube and lobes pubescent with evident sericeous hairs in H. fauziana ssp. fauziana vs only tube finely pubescent in H. fauziana ssp. angulata).
