Hoya sp. IML-557 What Is It Really?

Hoya sp. IML-557 I believe is a plant that really came with the wrong label, but I’ve kept it all of these years because of the phenomenal houseplant that it is.  It is a very easy growing plant with some of the most beautiful leaves in the Hoya world.  So even if the ID is incorrect, I will continue to keep this Hoya as long as I’m keeping plants.
