There are some collections - claimed to be recently acquired from David Liddle but not all of the plants have IML numbers - on Ebay. I want to caution some of the newer members that the H. ovalifolia offered is NOT considered a valid name and, frankly, I don't see that hoya in the picture. I happen to have the hoya and the leaves are quite striking...and NOT in any of the sellers pictures.
So...caution. This seller has had some of the IML cuttings for a short while and I seriously doubt they have large enough root systems to be sold. On a personal/professional level - I wouldn't trust that seller any further than I could throw the Queen Mary.

Thank you Carol for the heads up!!
