Insectivorous Plant Society
The Insectivorous Plant Society (食虫植物研究会 Shokuchūshokubutsu kenkyū-kai), often abbreviated as IPS, is an organization based in Chiyoda, Tokyo, Japan. Founded in November 1949, it is likely the oldest carnivorous plant society in the world. It celebrated its 50th anniversary in November 1999 at the Diamond Hotel in Tokyo. The society is named after Charles Darwin's 1875 book, Insectivorous Plants.
The society's chairman is Sadashi Komiya, professor emeritus of The Nippon Dental University. He is joined by the two vice chairmen, Momozo Tanaka and Yoshiyuki Sodekawa, as well as ten other committee members. Total membership to the society is around 530, the vast majority from Japan. The society already had around 300 members in the early 1970s. Five society meetings are held each year at The Nippon Dental University, usually in the months of January, April, June, October, and November.
