The Mammillaria Society was founded over 30 years ago with the aim was of promoting and furthering the study of the cactus genus Mammillaria. This was later extended to include Coryphantha and allied genera such as Escobaria, Thelocactus, Gymnocactus and Neolloydia. The Society has a world-wide membership.
Members range from professional botanists to enthusiastic amateurs.
All share a common love of the genus and a wish to increase their own knowledge and share this with fellow members. The Mammillaria Society Journal is published quarterly, starting in February each year, usually in the second half of the month. Journal back numbers are sold by volume. Recent years are much in demand and several years have already sold out. The Society has its own badge , available only to members.
