Louis Cutter Wheeler

Louis Cutter Wheeler (1910–1980) was an American botanist and professor of botany with an international reputation for his research on Euphorbiaceae.

Biography
Louis Cutter Wheeler's father was a citrus farmer in California, where the summer appearance of the "intricate inflorescence" of Euphorbia albomarginata (rattlesnake weed) aroused Louis's interest in botany. After attending La Verne Junior College, he studied botany from 1931 to 1933 at UCLA under Carl Epling and from 1933 to 1934 at Claremont University College under Philip A. Munz. After graduating in 1934 with a master's degree, Wheeler worked for the U.S. Forest Service in the Siskiyou Mountains and in the Angeles National Forest within the San Gabriel Mountains. From 1936 to 1939 he was a graduate student at Harvard University. He was a co-collector with Bernice Giduz Schubert.

"Specialising in the Euphorbiaceae by this time, he published a revision of Euphorbia subgenus Chamaesyce in Canada and the U.S. (except for Florida), giving typifications of 49 taxa. He produced more than 20 other papers between 1934 and 1939, when he was awarded his PhD."

From 1939 to 1945 Wheeler was a botany instructor and research assistant at several different universities. At the University of Southern California, he became an assistant professor in 1945 and was eventually promoted to associate professor and then full professor, retiring as professor emeritus in 1975.

"It was in 1969 that his association with Ceylon began as Wheeler was recruited to collaborate on the Flora of Ceylon project, providing an account of the Euphorbiaceae. This led to four visits to the island, where he was disappointed not to be able to carry a gun for protection against dangers he believed he would encounter, such as stampeding elephants. The most alarming occurrence, in reality, was when locals threw cobras into his compound."

The Flora of Ceylon Project was supported by the Smithsonian Institution, the Ceylon Department of Agriculture, and the University of Ceylon, Peradeniya. Funded by the Project, Wheeler collected in the Puttalam District (1969), Anuradhapura District (1971), and Kandy District (1977).
