The spreading leaves are stalked, the fleshy petioles are 1 cm long. The leathery and bare leaf blades are lanceolate-elliptical, 6.5 to 9.5 cm long and in the middle 1.8 to 2.3 cm wide. The base of the spade is rounded, the apex is pointed.
The umbel-shaped, upright inflorescence contains only a few flowers. The bald inflorescence stalk is round in cross section and 5 to 6 cm long. The flower stalks are thin, glabrous and about 3.5 cm long. The sepals are ovate-oblong 2 mm long and end bluntly. The corolla is wide, bell-shaped, the lower half is fused. The corolla lobes are triangular-egg-shaped and end blunt. They are hairy on the inside, the edges are covered with cilia, on the outside they are bare and about 1.1 cm long. The corolla lobes are fleshy, the inner process is elongated and short beak-like, the outer process is elongated and with a longitudinal groove, slightly ascending. The anthers are trapezoidal, the translucent process is egg-shaped and ends bluntly. The anthers protrude a little beyond the tip of the corolla lobes. The stylus head is conical. The pollinia are elongated with a keel on the outside. The caudiculae are short and thin. The corpusculum is rhombic and very small.

The Plants of the World online accepts Hoya bandaensis as a valid taxon. Whistler, however, considers Hoya chlorantha to be a synonym for Hoya betchei . Other authors have not followed him in this. Hoya chlorantha Rech. Is accepted online by Plants of the World as a still valid taxon.
