Hoya for id from Siliguri:: NS June 09 : 13 posts by 6 authors. Attachments (5).
This beautiful epiphyte was shot near Siliguri (W.B.)..
This is a Hoya sp. …H. verticillata ??

Please give your opinion regarding specific id..

Wow, great find …

Hoya alright since I photographed H. carnosa a few days ago here in California. Looks ver similar. Would be helpful if we know the differences.

Thanks for your early inputs …

I was considering this being one from H. verticillata or H. carnosa ..

tha pictures of the tiny flowers are so beautiful…they almost look artificial.

Hoya verticillata, acuta and parasitica are all quite difficult to differentiate. If there are references on the flora of Bengal, it could help

A reply from maker of World site on Hoyas:

“I sure looks like a species from the parasitica complex, but it’s extensive and flowers come in many colors (also growing condition affects the color) so it’s difficult to pin point exaclty which one”

Attached here KEY of three Hoya in ‘Bengal Plants’. Attachments (1).
Roxburgh’s note on Asclepias parasitica reads, “……. leaves opposite….. firm fleshy texture… veins scarcely conspicuous above, and invisible underneath, ….. petioles short, round, ash coloured, in fact more like a part of a branch….” But, Wight’s illustrations shows leaves are pinnately veined. I do not know if this is the same as Hoya parasitica Wall. ex Traill.
A website provides some information on Hoya The author throws some light discussing H. parasitica, H. acuta and H. verticillata. According to him Hoya acuta does not have tri-nerved leaves. Also, Hoya verticillata does not have tri-nerved, quinquenerved, or palmately veined leaves (please note the graphics in
FoC has only one species with 3-veined leaves –
I hereby do not attempt to ID your plant. I send you this mail only because I have spent past two hours just to know what Hoya is! Whatever species it may turns out it is a heavenly (if there is any!) creation…. and excellent photographs as well.

Thank you very much for sharing this wonderful finding.

Pl. also see Hoya acuta

Herbarium sheet marked as Hoya verticillata (Vahl) G. Don can be found at KEW –

Can this Hoya be labelled as H. parasitica (Roxb.) Wall. ex Wt.?

Leaves look a bit different from those at POWO and Flora fauna web

Image from GBIF!

It is a very variable species, I am sure of this.

Pl. see the earlier discussion in the matter at Hoya for id from Siliguri:: NS June 09

for me its hoya parasitica

I went through the discussion and you are correct about the confusion. I was initially not sure where to place it because I have myself observed several variations of the flower colour and leaf characteristics in the safe forest growing in different tree trunks. I also communicated with Dr. Michele Rodda in 2018, regarding this, and he was with the same opinion. It should be better placed as H.verticillata? in eFI.
My photographs lack details, sorry for that. It might be among the varieties proposed within the species.
However, Attached is an article which might help.
