The Society

Society History

Parasitic plants have been a source of scientific interest for many years and the subject of international conferences since 1973. That was the year of the first International Symposium on Parasitic Weeds that brought together a group of researchers who were (and still are) passionate about parasitic plants. The loosely organized group held major symposia for nearly 3 decades (See under Meetings), often interspersed with specialized workshops on Striga, Orobanche, or non-weedy hemiparasites.
In 2000, a number of these researchers met in Nantes, France to work out details of a society structure and write a constitution. This was presented to the parasitic plant research community the following year and the first General Assembly of the International Parasitic Plant Society (IPPS) was held in Nantes (France) during the International Parasitic Weed Symposium on June 4, 2001. In this meeting the General assembly elected the IPPS board – consisting of André Fer, president; Patrick Thalouarn, vice president; Daniel Joel, secretary; Jos Verkleij, treasurer; James Westwood, editor – and approved the Constitution. The society was officially registered in The Netherlands in 2001. The society continued to promote the ideals of the founders in 1973, and now organizes biennial conferences dealing with all parasitic plants to keep up with the accelerating pace of discovery.

IPPS Awards

Honorary Fellows of the Society

Honorary Fellowship may be awarded to an individual for outstanding contribution to the field of parasitic plant research. The Fellowships will be awarded at the occasion of the General Assembly meeting. The recipients need not necessarily be members of the IPPS. No more than two such awards may be presented at any one Assembly. The honorary Fellows should be selected and approved by the Executive Committee well in advance of the meeting so that they can participate in the annual meeting. The President will notify the Honorary Fellows immediately after approval by the Executive Committee. After retirement, Honorary Fellows are entitled to lifelong free membership.
