Hoyas  IV


Hoya MM, a hybrid from Hawaii.
The flowers of H. obtusifolia smells like mango but  they never open fully, prefering instead to form drooping claws. This is a large thick vine the likes of H. diversifolia but is much rarer and grows very high up in the canopy. This plant was collected from Peninsula Malaysia from a fallen tree where it was climbing rampantly all over its trunk. The vegetative feature does not look like a typical Hoya al all.
The  heavy flowers of  Hoya mitrata from Thailand, Borneo and Malaysia. Like its relative H. darwinii, this species has 2 types of leaves, the normal type and the cabbage-type - the latter attracts ants to build nests there.  The leaves are large, thick and lightly streaked with white. Contrary to Rintz comments about the species, the form I have is very free flowering whole year through - the essence to success is strong light and good watering.





Hoya waymaniae is a new species from Borneo described by Dale Kloppenburg. The leaves are very thick and turn red in the sun. The orange bloom was borned on a long peduncle. This species appears to rot easily so watering needs to be controlled. The peduncle tends to drop off after flowering.

The thin hard leaves of H. caudata appear to be lichen covered. This is a very slow vine and has been found in Malaysia, Thailand and Borneo. The flower is very distinguished, having ciliate hairs emerging from corona.

Hoya macrophylla is a large leaf species from SE Asia. It is also a common plant in Singapore, where I have seen plants laden with heavy succulent leaves measuring around 15 x 23cm. Singapore plants (pictured left) appear to have rotund leaves while in mainland Malaysia, the leaves are more elongated 

H. hypolasia is one of the many interesting Hoyas species Schlecter had described from PNG.  This has a dark hairy wiry stem and soft long hairy
leaves shown in the 2 above photos. The plant is not fast growing and cuttings may take some time before becoming established.  

Hoya densifolia is from the Philippines and has similar shrubby habit as H. multiflora.
