If any one is interested I now a list of documented Mammillaria seedlings for sale. Over the last few years I have grown a load of Mamm's from seed, from various sources. There are 75 lots on the list with more going on next weekend and the price is £1 or 1 euro per seedling. In some cases there may be only 1-2 and in others there are 10-20 avaiable. I am also happy to swap for other documented Mamm's.
If anyone would like the list, in word doc 2000, then E-mail me at mark.mccormac@btconnect.com
