The Uk Mammillaria Society is loooking for a supplement to the August 1971 Journal which was described as the most important study on the genus Mammillaria that had been published by the Mammillaria Society up to that point. It included Mr Hunt's proposals for the classification of Mammillaria species. The editorial also says that it was simultaneously published in the journal of the CSSGB.
As part of a scanning project to convert all back issues to DVD, we would like to find this supplement, borrow it for a short period so that it can be scanned, and then of course return it to its owner.
Please contact me if anyone has access to this document.
