HOYA PARASITICA PDF

This is a hoya that is very talked about. Some say acuta is the "correct" name for the hoyas in circulation as som acuta, parasitica, verticillata and some say it should be verticillata I have now decided to have both descriptions on my website and I will link the different hoyas after the names they had when I got them Hoya acuta comes from Indonesia, Thailand and Malaysia.

Hoya carnosa Hoyas are evergreen perennial creepers or vines or rarely, shrubs. They often grow epiphytically on trees; some grow terrestrially, or occasionally in rocky areas. They climb by twining, and with the employment of adventitious roots. They have simple entire leaves , arranged in an opposite pattern, that are typically succulent. Leaves may exhibit a variety of forms, and may be smooth, felted or hairy; veination may be prominent or not, and many species have leaf surfaces flecked with irregular small silvery spots.

The flowers appear in axillary umbellate clusters at the tip of peduncles. Hoya peduncles are commonly referred to as spurs.

In most species these spurs are perennial and are rarely shed. Schuman in diameter. Flower form is typically star-shaped, with five thick, waxy, triangular petals, topped with another star-shaped structure, the corona.

Colours on most species range from white to pink; there are species that exhibit yellow to orange, dark reds to near-black, and there are green flowers. Many are sweetly scented. Pollinators include moths, flies, and ants. Pollination is poorly understood, but plants left outdoors in temperate regions do sometimes produce seed, indicating pollination by local insects. Seeds are borne in twin pods, actually follicles, are generally light, and are dispersed by the wind by means of a small tuft of silky fluff.

Germination is rapid, but viability is not long. Several species exhibit adaptations for mutualism with ants by providing modified leaves for domatia "homes" , much as in the related genus Dischidia ; H. Leaves[ edit ] Hoya leaves vary in size, texture, colour and venation. Hoya latifolia G. Hoya coriacea Blume, has been reported to have leaves as long as two feet in length.

There are hoyas with almost perfectly round leaves and others with linear leaves Hoya linearis Wall. Don and Hoya teretifolia Griff. One popular species, Hoya shepherdii Short ex Hook. Hoya linearis Wall. Don is covered with fine downy hair and resembles masses of Spanish Moss Tillandsia usneoides hanging from trees in its native habitat.

Some Hoya leaves are smooth and shiny; some are covered with hairs. Some Hoya leaves appear to be veinless while others have very conspicuous veins of a lighter or darker colour than the rest of the leaves as in H. Some have leaves that are mottled with speckles of silvery white Hoya carnosa R. Some hoyas have leaves that are thin and translucent Hoya coriacea Blume ; some are so thick and succulent that they look more like crassulas than hoyas Hoya australis ssp.

One of the most succulent, Hoya kerrii Craib, has obcordate inverse heart-shaped leaves, with the cleft away from the stem. Flowers[ edit ] Hoya mindorensis Hoya flowers are all shaped like five pointed stars. They grow in umbels , or in some species singly. Umbels can reach impressive proportions in some species, and many species have individual flowers well over three inches in diameter H. The single-flowered Hoya pauciflora Wight makes up for its paucity by its flower size of nearly an inch and a half in diameter produced at any time of year.

Textures of flower surfaces may be glabrous and shiny, to matte, to finely haired, and some being quite hairy. One of the two clones of Hoya mindorensis Schltr. Blue, purples, and violets do not appear to be represented in the genus Hoya.

Vermont Hoyas Home

This hoya comes from Indonesia and it was described in There are many varieties of this hoya and different colours of the flowers and some variations of the leaves. Some people want to call this Hoya parasitica, and some say the true name should be Hoya verticillata. The leaves are ovate, quite thick and hard, light green with lighter veins and some silver flecks. Some verticillata have more visible veins and more flecks than others. One variety has leaves with a lot of silver flecks. Once a cutting is rooted and established, Hoya verticillata is a fast growing plant with thick foliage.
