features

Hoya benguetensis is a twining plant with rather thread-like, branching and bare shoots that have relatively few leaves. The shoots, which are round in cross-section, measure only about 3 mm in diameter. The leaves have a 5 to 8 mm long, fleshy stem. The bald, fleshy leaf blades are elliptical or ovate-elliptical and thick leathery. They measure 6 to 10 cm in length and 2.5 to 4 cm in width; the outer end is pointed.

The inflorescence is many-flowered (up to 10 flowers, 9 to 12 flowers) and hangs down. The peduncle is usually short, but can be up to 7.5 cm long. The yellowish or reddish single flower is spread out in a star shape and has a diameter of about 1 cm. The bare flower stalks are thin, thread-like and 1 to 1.3 cm long. The sepals are about 2 mm long, blunt-egg-shaped and glabrous. The corolla lobes are bare on the outside and very small papillae on the inside. The corolla lobes are egg-shaped, 3 mm long and pointed at the outer end. The staminal corolla lobes are reddish in color. The outer process is blunt and slightly ascending, the inner process blunt-beak-shaped. The outer half of the inner process is keeled. The pollinia are club-shaped, the translator is quite small. The corpusculum has the shape of a rhombus. The flower has little or no scent.

Geographical distribution and habitat
