Diversity of Erythronium in the Eastern United States

In a few recent papers (the latest in this journal for December 1940) I have pointed out that several fairly common plants have long been misunderstood because current descriptions of them have been based on herbarium specimens, in which the flowers had lost their shape or color, or both, or the fruit or some other essential part was lacking. John M. Fogg, Jr., in Rhodora for May, 1940, stressed the importance of collecting more complete specimens than has been customary, and supplementing them with information that may be lost in the drying process, such as. the color of the flowers. In the case of Erythronium he suggested recording flower colors, but said nothing about the fruit, which now seems to be equally important, as will be shown presently.
