Hoya ignorata is a species of flowering plant in the dogbane family Apocynaceae. It is an epiphytic shrub native to Vietnam, Thailand, Peninsular Malaysia, and Borneo.
Hiepia corymbosa is a synonym for the species. The genus name of Hiepia is in honour of Tiên Hiêp Nguyên (b. 1947), a Vietnamese botanist, who organized field research excursions in south-east Asia.[1] The Latin specific epithet of corymbosa refers to Corymb, which is derived from the Ancient Greek word korymbos meaning "bunch of flowers or fruit".[2] Hiepia and Hiepia corymbosa were first described and published in Turczaninowia Vol.14, Issue 3 on page 6 in 2011.
