Hoya epedunculata is a plant of the genus of wax flowers ( Hoya ) of the subfamily of asclepiadoideae (Asclepiadoideae).
features
Hoya epedunculata is a small, epiphytic , climbing subshrub with thread-like, sparsely branched shoots. The richly leafy shoots are flexible, round and bare in cross section. The outspread leaves are stalked, the leaf stalks, which are slightly runny on top, are 1 to 1.3 cm long. The leathery leaf blades are elliptical, 11 to 18.5 cm long and 4.5 to 7.5 wide in the middle. They are bare on the top and bottom. The base is wedge-shaped, the apex is pointed. The leaf nerve is palm-shaped with 6 to 7 secondary ribs extending from the midrib, some of which branch out at the end.
The terminal inflorescence contains only one to about 5 flowers without a common inflorescence stalk. If there are several flowers, they are arranged in an umbel shape. The very slender flower stalks of about the same length are up to 3.5 cm long and bare. The egg-shaped sepals are about 2 mm long and covered with fine warty outgrowths. The edges are covered with cilia on the outside. The apex is blunt. The broad, bell-shaped, pink-red one. The corolla has a diameter of 4.2 cm. The petals are fused in the basal half. They are bare on the outside and fluffy-papillae on the inside. The edges are densely covered with cilia. Apices of the triangular petal lobes are pulled out lobed. The obovate, yellowish-white corolla lobes are spread out horizontally. They are about 3.5 mm long. The inner process is pointed and ascending, the outer process very blunt. The sides are hardly thickened.
The pollinia are elongated and slender, sloping slightly inward at the apex. The outer hyaline border extends to below the apex. The corpusculum is very small and rhombic. The caudiculae are short and thin.
Similar Art
The corolla is similar to the corolla of Hoya torricellensis but is much larger. The leaves are wider and the flowers do not have an inflorescence stalk. The sepals and the petals are covered with cilia. Hoya evelinae Simonsson & Rodda has smaller leaves, inflorescences along the stems and obovate corolla lobes .
Geographical distribution and habitat
The species occurs in the Toricelli Mountains in Papua New Guinea . She found it worse there, blooming in forests at 900 m above sea level.
Taxonomy
The taxon was described by Rudolf Schlechter in 1913 . The holotype is kept under the number Schlechter # 20102 in the herbarium of the Botanical Garden Berlin . The Plants of the World online database accepts Hoya epedunculata as a valid species.
