Perhaps the ones shown online are actually variegated Kentiana.
The leaves of my wayetii are smaller than I would have imagined from only seeing images.
My daughter (who knows nothing about hoyas) immediately remarked on how the leaves had pretty dark edges, even though I only showed her the plant on my phone during a video call. I was surprised she could notice it on a small phone video screen.
When i was looking at the plant in the store, I saw lots of little white spots and specks on many leaves, and at first I thought Oh No, that must be a bug infestation or something. Then on closer inspection, the specks seemed to be just dried liquid specks. Then I found a leaf that was half broken off, so i broke off another little piece from that leaf, and immediately a milky sap came out. Mystery solved! No bug infestations, just dried sap spots and old leaf bumps and bruises of various kinds. Most of the white spots came off at home with a nice warm shower from my kitchen sink spray. It must have enjoyed that 'jungle shower'.
