Hoya Bella is a plant of the genus of wax flowers ( Hoya ) of the subfamily of asclepiadoideae (Asclepiadoideae).
features
Hoya bella is a perennial , epiphytic subshrub with thin, branched shoots. The downy, hairy shoots are curved and hang down. They are heavily leafed, the internodes are only a few centimeters long. The opposite leaves are stalked, the petioles are thick and about 2 mm long,
The fleshy leaf blades are lanceolate-egg-shaped or oblong-trapezoidal, 3 cm long and 1 to 1.5 cm wide. The apex tapers to a point, the base is rounded. The top is dark green and shiny, the bottom is lighter and matte. With the exception of the midrib, the leaf veins hardly emerge. The central rib is sunk in a groove on the top and protrudes on the underside.
The umbellate inflorescences are terminal and hang down. The top is flat with 4 to 8 (rarely up to 13) flowers. The flowers are arranged around a central flower. The inflorescence stalks are up to 3 cm long and not persistent. They fall off completely after flowering (or fruiting). The whitish flower stalks are up to 1.5 cm long, according to the position in the inflorescence. The sepals are elliptical and spread out. The star-shaped corolla has a diameter of 1.8 cm. The petal lobes are triangular, 7 mm long and 7 mm wide at the base. The apex is pointed. The corolla is hairy inside. The edges are bent outwards, so that a flat-V-shaped cross-section of the corolla lobes results. The secondary crown is glassy-pink and spread out almost horizontally. The staminal corolla lobes are triangular. The inner process is blunt and slightly ascending; the top is convex. The outer process is pointed. The purple-colored upper side is concave, the lower side is a little paler. The anthers are thin and membranous. The flowers smell intensely sweet, especially in the evening and night, and last up to two weeks. They excrete little nectar. In a flowering phase, new inflorescences are constantly formed, so that several inflorescences are always open at the same time.
