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..

This book has been a long time in preparation and is a welcome addition to the literature relating to the Euphorbiaceae. The Society Treasurer Bob Potter, and Chairman Rikus van Veldhuisen, have traveled with Rolf and Alma in South Africa and Namibia, and can both attest to their superior knowledge of the Genus.
