Final Photo of Hoya patella ‘White’ For Now

I know Hoya patella was discovered in Papua New Guinea, but I would like to know the details of where the Pink and White varieties were discovered.  Were they living near each other?  I would like to know more about the genetics involved that would produce the two colors.  If anyone has any answers, please email me at dougchamberlain61@gmail.com
