Until recently botanists have considered our spe- cies a variety of Botrych- itim tcrnatum. The latter was discovered in Japan by Thunberg and there' seems to be good reasons for believing ours to be a different species. It is found from New Brunswick and Ontario to Minnesota, Mex- ico and Florida, frequentingsliady fencerows and swampy woods. There are four forms in the West and one in the South that are closely related to our species and are often classed as varieties of it. Small forms from New York and New England are sometimes referred to B. Matricarice of Europe, and a form with larger blades on shorter stalks is the form intenne- dinni. The species and the varieties 57.
