Hi K&C! I believe and this is only a guess is you have a Lacunosa 'poonsak' its very similar to lacunosa but the eaves are slightly different but its still part of the lacunosa family.

Here's one from "Apodagis" website:
'Poonsak'

Here is a link that might be useful: Lacunosa 'poonsak'...Gardino's

Thanks, pug! I think this could be a 'Poonsak'. I'm going to keep looking at pics. You're probably right, though :)

Yep still just Hoya lacanosa it's just that this species has a fairly large range so there is quiet a bit of difference between plants from different locations. I even have a Hoya lacanosa 'Giant' which has rather large leaves vs the usual lacanosas you see. I think your plant might be Hoya lacanosa var. lacanosa because lacanosa 'Poonsak' is a very dainty variety with small narrow leaves.
