NEW 2023

Membership Renewals for 2023

You will notice that there is no option to renew your membership for 2023. This is because Volker, our hard working editor, was seriously ill last year and was unable to process volumes 2 and 3. Thankfully, he is on the road to recovery and is working to catch up on the missing journals.

It was decided that the Society would not be issuing any journals for 2023 but that we would allow Volker to catch up by producing volumes 2 and 3 of 2022 during this year. Consequently there will be no subscription fees for the coming year. We hope you understand this decision and we must look forward to the remaining two volumes during 2023.

You are of course still be able to use the PayPal buttons to subscribe for 2022, 2021 and 2020, and are also able to purchase back numbers.

The committee wishes you all a Happy New Year and good growing for 2023.

Regards, Bob Potter

Treasurer and Membership Secretary

Journals of the Euphorbiaceae Study Group Bulletin available

The Netherlands Succulent Society have some journals of the Euphorbiaceae Study Group Bulletin available.

The Euphorbiaceae Study Group was the fore runner of our International Euphorbia Society and was formed By Daphne and Albert Pritchard in the late 1980s. There was a bulletin issued 3 times per year and was put together by Daphne and Albert and contained stuck-in photographs to accompany the text. The articles they contained were varied and of much interest, these bulletins are quite rare now and this is a good opportunity to acquire some of them.

The full list and how to buy them is available here..
