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.



Now is the time to enter the Oxford Show, and after the show itself ends, listen to our guest speaker, Wolter ten Hoeve of the Netherlands who will talk o his recent experiences in the field in Mexico. For more information see our Events page.

The May 2016 issue of the journal is now available online. 

Members renewing and new members should now all have access to the 2016 area and the journals to date. If you think we have missed you off, then please let us know asap.

New Plant of the Month - Mammillaria sphaerica just added.
