Hoya eitapensis is a plant of the genus of wax flowers ( Hoya ) of the subfamily of asclepiadoideae (Asclepiadoideae).

features

Hoya eitapensis is a twisting , epiphytic plant with branched, thread-like shoots that are glabrous and only loosely leafed. The leaves are stalked and spread out upright. The leaf stalks are about 2 mm long. The leaf blades are elliptical, 3 - 5 cm long and 1.2 to 2 cm wide. They are fleshy and bald. The apex is blunt, the base is wedge-shaped.

The umbel-shaped inflorescence consists of 20 to 35 flowers. The inflorescence stalks are up to 5 cm long. The very thin flower stalks are up to 2 cm long and more or less hairy apically. The sepals with short hairs are oval-triangular, 1.75 mm long and end blunt. The yellowish-white corolla is wheel-shaped and about 8 mm in diameter. The corolla lobes are ovate, tapering to a point and apically bent back. They are glabrous on the outside, very short papillae to slightly downy hairy on the inside. The 2 mm long tips of the secondary crown are oblong and flat. The inner, long, pointed process is slightly ascending. The outer process is blunt. The pollinia are elongated-cylindrical, apical weakly sickle-shaped. The translator arms are very short, the very small corpusculum is rhombic in shape. Fruits and seeds are not known.

Geographical distribution and habitat

The species occurs at Eitape (until 1914 Berlinhafen ) in Papua New Guinea in tropical forests only a little above sea level.
