My cello teacher has two hoyas growing from a pot - possibly seperate plants but she's not entirely sure. One has flat leaves, one has curled leaves. Their flowers are quite similar however, the curled leaf plant's flowers have more of a chocolately smell. Are these the same species with a reversion to wild type in one branch or two different species? Can anyone id?

Above is flat leafed plant with its waxy spots (is that normal?)
