Hoya bandaensis is a plant of the genus of wax flowers ( Hoya ) of the subfamily of asclepiadoideae (Asclepiadoideae).
features
Hoya bandaensis is an epiphytic , high climbing plant with twisting shoots. The fleshy, flexible shoots are branched, but not very leafy and bare. The leaves are stalked, the petioles are 1.5 cm long and thick. The fleshy leaf blades are elliptical, 10 to 12 cm long and 5 to 7 cm wide in the middle. The base is pointed and the apex is also pointed. The top and bottom are bare.
The umbel-shaped inflorescence is multi-flowered. The peduncle and peduncle are glabrous, thread-like about the same length, 3 to 3.5 cm. The sepals are 3 mm long and lanceolate, pointed. The edges are covered with very fine cilia; otherwise they are bare. The white corolla is wheel-shaped and measures 1.4 cm in diameter. The corolla lobes are egg-shaped-triangular, outside glabrous, inside fine and densely papilous. The edges are bent back. The fleshy corolla lobes are spread out horizontally. The inner extension is rhombic with a beaked tip, the outer extension is square and the apex is split in the middle (bifid). The anthers are square-trapezoidal, the transparent appendages ovate and pointed. The pollinia are elongated, truncated obliquely inwards at the apex. The outer transparent edge is designed like a keel. The caudiculae are very short. The corpusculum is rhombic, very small with two points at the lower end. It is less than a quarter as long as the pollinia. The stylus head is short-conical.
