M.columbiana columbiana AIAPS 738

M.columbiana columbiana ( v albescens ) AIAPS 738. Capitanejo, Colombia.
I have many different collections of M.columbiana but this is the only one flowering at the moment. It was grown from seed from M.Lacoste via the Doug Rowland 2007 seed list, sown 20-7-07, germinated 29-7-07.



I have seen this and other Field Numbers, in relation to M.columbiana, with the same number and location but with a GX ( Guy Xhonneux ) Acronym. I believe AIAPS may relate to the French Cactus Soicety but I am not sure. Can anyone enlighten me has to the contection.
