Hoya bauensis

Hoya bauensis was described by Ted Green in 2021 (Asklepios) and is named for the Bau district of Sarawak, Borneo, a limestone-hill landscape. It is very rare in cultivation; grow it as a warm, very humid Bornean hoya, and if it proves to be a limestone lithophyte give it a slightly mineral, well-aerated mix.
