Paige, you say he wants to extract colchicine. If that means extracting pure colchicine, I'm not sure where to send you. But if what he wants to do is to induce tetraploidy using crude preparations of crushed colchicum corms, that's different. Old issues of the Yearbook of the North American Lily Society contain accounts of doing this. I won't have the chance to do the search anytime soon, but I'm pretty sure they're there. If I were doing the search, I would start with the issues from the 1960s. Jim McKenney
