Hoya kerangasensis
Hoya kerangasensis (Rodda & Rahayu, 2022) is named for kerangas, the heath forest of Borneo that grows on white sand: a low, open, nutrient-poor forest that is brighter, hotter by day and drier in the air than tall rainforest. Give it more light than most lowland hoyas, warmth, and a lean, sharply drained acidic mix.
Where it grows wild
