I couldn't reply to my original post, so had to post this under new heading.

"""Cruising thru the forum, I saw your query. I am fairly sure that your Hoya is H. fungii, also known as H. carnosa from Vietnam. H. carnosa has many cultivars but this is a separately recognized species, probably related to H. carnosa, though. For my taste, it has more attractive leaves, larger umbels and prettier flowers than H. carnosa. Good find! Enjoy

I found this during my searching. This is from a grower, seller in Hawaii. I find it most interesting. I'll have to dig a little deeper. LOL Too bad we don't have a 'genie' to give us the answers we want.
