Hoya III

Some of the redder ones ....

Hoya lobbi is a shrubby plant from Myanmar and N. Thailand. Apparently, the earlier form that was distributed in the West was quite difficult in lowland but more recent collections appear more robust and floriferous. 

H heuschkeliana is a small, slow growing beauty from  PNG - there are 2 colour forms, the pink one shown here and a yellow coloured form. The corolla is fused to form a tube rather like most Dischidia.

Hoya imperialis. This is a robust  mangrove plant from Borneo and Peninsula Malaysia that has rather non-hoya vegetative features. There are many colour varieties of the flower: bright red, dull red, purplish and even white. A Unique feature is the  corona which is very large and heavy-looking.   

H. meliflua is a robust vine with large umbel of pink flowers. It is quite floriferous in Singapore lowland climate.

Hoya mindorensis is from The Phillippines. This is a modest vine and vegetatively very similar to H. verticiliata - but the bloom is decidedly different in appearance and as far as I can tell, scentless..
Hoya mcgillivrayii was first described by F.M. Bailey in 1914 and has since been highly sought after. It is found in diverse habitats (from swamps to dry seasonally  dry deciduous forest) in the Cape York region of Northern Australia as well as PNG. Several forms are available and the one shown has white centre.  

This is a close relative of H. mcgillivrayii and at one time considered synonymous - the bloom is quite different though, having a claw-like appearance.

This is an Eriostemma  hybrid named "Ruthie" which I obtained from Ed Guilding. It is the most frequent blooming Eriostemma I have.

 

PS: Eriostemma has recently been separated from genus Hoya due to their unique features.

 

PSS: I understand the separation was not accepted by Taxonomists community.

This is a H. archiboldiana, a close relative of H. mcgillivrayii.
