Hoya cutis porcelana is a cutie, and its leaves are like porcelain. I can't figure out where they get the name though....
Another typical, easy-growing hoya, this is not a common one, but climbs or trails just like a carnosa, only with a different leaf and a different flower!
These are very good sized, full plants in 4.5 inch pots. Trailing nicely as well. Photos are of the plants available.
Letting the soil become COMPLETELY dry between waterings, bright light, and humidity are the ways to keep this plant (and many other Hoyas) happy and healthy.
