Hoya buntokensis

Hoya buntokensis was described in 2021 by Rahayu and Rodda from Bornean material, its name pointing to Buntok on the Barito River in Central Kalimantan. It is a recent, rarely grown species from the humid Bornean lowlands, so at home it wants warmth, high humidity and even moisture all year with no dry rest.

Where it grows wild

Presumed an epiphyte of lowland forest in the Barito basin, where peat swamp, riverine and heath forest meet. No species-specific habitat notes were reachable beyond the place of publication.

No elevation is recorded. The single climate point used here sits at about 430 m in the interior of western Borneo, which is likely higher and cooler than the Buntok lowlands the name suggests.
