BTW, the purity of any L. Triangulum that can't be traced to WC founders could be called in to question. crossing was rampant in the bad old days, partly out of ignorance that these were distinct sub-species. As I said, the Pueblan x Nelson albinos have been around for quite awhile and if the original crosses were repeatedly crossed to "pure" Pueblans, the Nelson's influence could be largely negated in recent generations. with the obvious exception of the albino mutation. The good news is that the recognition of distinct ssp. is not a new occurrence and countless breeders have resisted the urge to cross them for a few decades now. I think most are what they are said to be. but in the case of Albino Pueblans where the Nelson's factor is not acknowledged, virtually none are what they are said to be.
