Wax plant is a common name for Hoyas, an older name, but still, I've got a Housplant books that calls it that, published in the 70s.

Any chance of a pic? That might help. I looked at the site you mentioned but didn't see one as you described. Carnosa leaves can be very variable indeed. I'm sure others will share their thoughts, even more so if you could share a couple of pix of it.

Thanks. I posted pics twice last night I don't know why they aren't showing up.

This leaf looks the most like a Chelsea and is very thick.

This leaf is long and very thin and the circled leaf is rounder and thick. I've never seen a Carnosa (in one plant) look so different.
