The leaves are dark green, hairy, and have grey spots intermittently dispersed. The flowers produced are extremely fuzzy with a light green corolla and a white corona with a bit of pink towards the center of the flower, with finally a yellow center. The flowers last about a week, and unlike other Hoyas, produce very little nectar. Additionally ...
Hoya obscura is a fast-growing, climbing species of Hoya in the dogbane family, Apocynaceae, found in the Philippines. [1] The plant's many aerial roots (which the vine produces along its entire length) will gradually adhere to vertical surfaces nearby, such as buildings, trees or poles, acting as anchors and enabling the plant to receive better sun exposure away from the ground.
Hoya carnosa Hoya mindorensis, Sydney, Australia.. Hoya is a genus of over 500 species of plants in the dogbane family, Apocynaceae, commonly known as waxflowers. [2] Plants in the genus Hoya are mostly epiphytic or lithophytic vines, rarely subshrubs, with leathery, fleshy or succulent leaves, shortly tube-shaped or bell-shaped flowers with five horizontally spreading lobes, the flowers in ...
The H. bilobata leaves have a variable, sub-orbicular or broadly elliptic shape, with the leaf base being rounded to sub-acute and the leaf apex being obtuse-rounded. The adaxial surface of the leaves are a dull, olive-green colour with the abaxial surface being a lighter green. Leaves are generally 1.7–2.2 cm in length and 1.3–1.8 cm in width.
A single flower (corolla) has a diameter of 1.5 to 2 cm. [5] Like most species of Hoya, H. carnosa flowers from specialised perennial peduncles; sometimes these structures are referred to as spurs. These appear from the axils of the leaves and stem; flowers may not be produced when the spurs first appear, but in time buds emerge from their tips ...

Hoya australis is a succulent climbing vine to subshrub that typically reaches a height of 4–10 m (13–33 ft). It has fleshy or leathery, elliptic, oblong, egg-shaped or more or less round leaves up to 150 mm (5.9 in) long and 120 mm (4.7 in) wide.
In systematic virus infections leaf spots caused by viruses show a loss of green colour in leaves, due to chlorosis which is a repression of chlorophyll development. [1] Leaves may yellow and have a mottled green or yellow appearance, show mosaic (e.g. chlorotic spotting) and ringspots (chlorotic or necrotic rings). [7]
