Hoya vaccinioides Hook.f.
The white corolla with clear lovely pink to purple corolla of H.vaccinioides looks very similarly to H.bella. This specie is founded in the west of Thailand near to border of Burma. It is shrubby plant same as H.bella but its leave is more ovate and fleshy than H.bella. The leave is about 1 inch lenght, half inch width and has a little bit pubescent. It is founded in the high altitude forest, so it is so hard to grow and bloom in Bangkok where is very hot.
