Welcome to the Mammillaria Society

Here you'll find details about the Society, about membership, and about our Journal and Annual Meetings and Shows. We try to feature a different species of MammillariaCoryphanthaEscobaria, NeolloydiaThelocactus or Turbinicarpus each month, and sometimes these include newly described species.

We hope you will share our delight in this genus of plants, that stretches from Central America and the Caribbean through all of Mexico and deep into the Western States of the USA. New discoveries are being made all the time, and this web site will feature them once described in the appropriate Journal.

Please also visit the Mammillaria Forum to talk with other Mammillaria enthusiasts in the UK and around the world, but do please note that while this is supported by the Society it is not run by us.

You do not need to register to look at our free content. You can see our events for the year, and there is a lot of information in the Plants of the Month section, and details of other useful websites etc. 

Mammillaria Society members who want access to the Members area should contact either Chris Davies or Pete Arthurs, who will then register you and give you access. This Members Only area contains digital versions of our Journals from 2011 onwards which may be downloaded. The provision of access will typically take up to a few days after contacting us. It is unfortunately necessary to do it this way as we have been receiving a lot of false registrations recently and the workload to remove these is much more than registering bona fide Society Members.  Trying to Register will take you straight to the logon page, and so will fail.

If you have any problems, please contact the webmaster for the site.



20th Jan update. By now many of you should have received the last journal for 2017, and have been ordering from our seed list. Many thanks go to our Editor for overcoming so many obstacles. On your behalf, many thanks, Alasdair.

Subscriptions for 2018 (Unchanged from 2017)

You can now join and renew safely and securely, using your credit card, through our association with PayPal, the world's leading on-line payments system. Alternatively you can download and print the 2017 Membership Application Form here.
UK Members using Paypal will be emailed a request for their current and past membership subscriptions to be considered as Gift Aid. The Society is in the process of applying for this. We would very much like all members to agree as it pushes further back the time when we have to consider again any increases in subscriptions. Do note that the only increases this year are to non UK membership, and these only to fully cover international postage costs.
Pricing is shown in British Pounds but you will be billed in your local currency. This means that Mammillaria Society membership is now available throughout the world.
PLEASE NOTE: Your Paypal receipt will have an old email address on it. If you need to follow up anything connected with your transaction, please contact This email address is being protected from spambots. You need JavaScript enabled to view it.
