Hoya pauciflora is a plant of the genus of wax flowers ( Hoya ) of the subfamily of asclepiadoideae (Asclepiadoideae).
features
Hoya pauciflora is a lithophytic or epiphytic plant with thin, rather creeping shoots. Fresh shoots often still grow in twists. On the bare shoots, adherent roots are usually formed at the nodes, and more rarely also at the internodes, with which the plant attaches to the ground. The leaves are opposite, but often tufted around the knot. They are stalked, the petioles are 2 to 6 mm long. The dark green leaf blades are oblong lanceolate or oblong linear, 2 to 5.5 cm long and 0.5 to 1 cm wide. They are thick and bare with a shiny surface. The underside is often speckled red. The apex is pointed to round, the base pointed or round. The edges are often bent back. The midrib stands out clearly, otherwise no leaf veins can be seen.
The inflorescences usually contain only one or two flowers. The peduncle is only very short. The peduncle is longer but thin and glabrous. The sepals are lanceolate, small and glabrous. The white corolla has a diameter of 2 cm. The corolla lobes are wide and end bluntly or somewhat pointed. They are bare inside or thickly covered with tiny downy hairs. The secondary crown is pink to dark purple in color. The staminal corolla lobes are egg-shaped, fleshy and sunk in the middle. The outer extension is round, the inner extension ascending like a spur. The follicle fruit is 10 cm long and very slender.
Similar Art
The habit and the arrangement of the leaves as well as the flowers are reminiscent of Hoya retusa , which can be easily distinguished by the shape of the leaves.
Geographical distribution and habitat
The distribution area of the species extends from southwest India ( Kerala ) to Sri Lanka . It grows there in damp mountain forests in shady places on large rocks and tree stumps. It rises up to 1600 m in the mountains.
Taxonomy
The taxon was published by Robert Wight in 1848 . Plants of the World online accepts the taxon as valid. Hoya wightiana Thwaites (1860) is considered a younger synonym .
