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.
Where it grows wild
Presumed an epiphytic or lithophytic vine in humid lowland to hill forest around Bau, Sarawak, where limestone outcrops rise through the forest; bright filtered light on trunks and rock faces.
Modelled at about 430 m; the type elevation is not available to us.
