Ross, the white pouch comes from the 'Candor Luminesse' clone, which I beleive has an HCC. Selfings of this clone will produce many pure green and white primulinums, no yellow even with aging. This cross has 'Gold Nugget' as a parent. This clone is quite yellow and the largest, best formed primulinum I have ever seen. It was a collected plant, I have never had a chance to photograph it, I think its blooming right now. A first bloom selfing of 'Gold Nugget' is 'Golden Child'
Both the flavum and the pupurascens forms of this species are wildly variable in shape and color - for a small sample goe to the primulinum section at
http://ladyslipper.com/paphsp.htm , and when you start saying "hmmm" keep in mind that these are all collected plants pictured, no human tampering.
