The Origins of Hoya Icensis

As near as I can gather from my limited time to scour the internet, Hoya Icensis was an accidental cross of unknown parentage in or near the AH Hoya Nursery in Thailand. It was originally called AH Seeds 023 and then was called Hoya cv. Patcharwalai. How and why it was then changed to Hoya Icensis, I have no idea, and anyone who knows the answer, please let me know!
