Hoya limoniaca is a plant of the genus of wax flowers ( Hoya ) of the subfamily of asclepiadoideae (Asclepiadoideae).
features
Hoya limoniaca is a perennial, climbing plant with twisting shoots. The almost bare, round in cross-section shoots are thickened at the nodes. The leaves are stalked, the petioles are up to 15 mm long. The leaf blades are egg-shaped, 7 to 8 long and 3 to 3.5 cm wide. They are leathery and thin, the apex is long and pointed, the base is rounded. The lighter leaf veins are clearly visible. The midrib is thin, a pair of secondary ribs emerge near the base and run almost parallel to the edge to the apex. The midrib and secondary ribs are connected by indistinct, transverse leaf veins.
The almost ball-shaped inflorescence has about 20 flowers. The peduncle is almost round in cross section, 2.5 cm long and sparsely hairy. The bare flower stalks are thread-shaped and 12 to 15 mm long. The sepals are egg-shaped, 1.5 mm long and end blunt. They are papillary on the outside, otherwise bare. The white to pale yellow, star-shaped corolla has a diameter of 1 cm. The petal lobes are egg-shaped and taper to a point. They are slightly bent upwards, but the tips are strongly bent back. The tips are bare on the inside or finely tiny papillosis. The side crown is almost flat. The staminal lobes are ovate, 4 mm long and pointed. The outer process is white, the inner process is reddish. The stamen processes are ovate-lanceolate and end blunt. The pollinia are elongated pear-shaped, approx. 600 µm long. The flowers smell slightly sweet.
Fruits and seeds are not known.
Similar Art

Geographical distribution and habitat
The range of the species is limited to New Caledonia.
