BY TIMOTHY J . MOTLEY B.S. in Botany, Eastern Illinois University ABSTRACT OF THESIS submitted in partial fulfillment of the requirements of the degree of Master of Science in Botany at the Graduate School of Eastern Illinois University Charleston, Illinois 1989 ABSTRACT One of the more interesting and attractive components of aquatic ecosystems is sweet flag, Acorus calamus L., a herbaceous perennial belonging to the Araceae, a primarily tropical family. Sweet flag is one of the few extratropical members. The primary purpose of this work is to present a compilation of the various traditional and contemporary uses of sweet flag by various cultures. Information regarding the known ethnobotanical and economic uses of the rhizome and aromatic essential oil as a flavoring agent is given, as well as its medicinal uses and value as an insecticide. In addition, a discussion of the nomenclature, history, and folklore of Acorus calamus is included. A discussion of the morphology of this unique plant is supplemented by drawings and color photo- graphs illustrating the features discussed. The chemical composition and experimental data sections relate to the connnercial importance and potential for future use of sweet flag. Concluding statements suggest the need for further research on the medicinal and insecticidal aspects of the alkaloids and oils. Several of the compounds isolated are similar to the derivatives of another important medicinal plant, the opium poppy. ACKNOWLEDGMENTS Thanks to all those who have helped me along the way. First I would like to thank my parents Roy and Joan and my brothers Gavin and Jeremy for all their advice and support. My thanks also goes out to Dr. Charles B. Arzeni for his advisement, friendship, and for helping me to open my eyes to new horizons in the field of Botany and life. Sincere thanks goes to Dr. John Ebinger, Dr. Andrew Methven, and Dr. Wesley Whiteside for their guidance and the many things they have taught me. Once again I give thanks to my artistic brother Jeremy for the help he gave me on the ink illustrations included in this thesis. I would also like to thank, for their help in translating three articles in the German language, Bettina and Andrea Krugler. Last of all, but not least, a special thanks to Kimberly McCord for her love, help, and moral support which helped me through this difficult time of my life and made it seem much easier.

In addition, information was obtained from interviews with people who have been exposed to the use of sweet flag. Furthermore, fresh material was obtained from Illinois for morphological, anatomical, and photographic study. This illustrated treatment supplements the ethnobotanical comments and focuses on the morphological aspects of the plant. 1 INTRODUCTION Sweet Flag, Acorus calamus L., represents one of the uncommon, but widespread, herbaceous, semi-aquatic components of aquatic habitats in the temperate to subtemperate areas of the world. It grows along the edge of ponds, in lake shallows, and river floodplains. In the Old World, Sweet Flag occurs in all the European countries, except Spain. It is also found in southern Russia, northern Asia Minor, southern Siberia, China, Japan, Burma, Ceylon, and India. In the New World it occurs in southern Canada and the contiguous 48 states of the United States. Sweet flag a member of the Araceae, has a rich in history dating back to early Greek and Roman medicine and was included in many of the early herbals. The plant is thought to be indigenous to India and was spread by way of trade and conunerce. It was later cultivated by vegetative propagation using it's creeping rootstock or rhizome (Grieve 1971). The rhizomes were also utilized extensively by the Chinese, Indians, American Indians, as well as many other cultures past and present. Sweet flag has been the subject of superstition and poetry. The candied rhizome is a European and early American confection. The fragrant oils obtained from the rhizome are used medicinally, to flavor alcoholic beverages, as a fragrant essence in perfumes and sacred oils, and for its insecticidal properties. The fragrant leaves, smelling of tangerine or citrus, were used on the floors of homes and churches to remove disagreeable odors and deter pests. More work has been initiated on the chemical compounds found in the rhizome to determine their uses as medicinal, antibacterial and antifungal agents. 2 NOMENCLATURE Folknames of
