Part II of Michigan Flora, now in press, will cover the families of dicots from Saururaceae through Cornaceae in the traditional Englerian sequence. Inevitably, some names will be used that are unfamiliar to many people, and perhaps some familiar names will be retained despite published suggestions that they be overturned. Usually, nomenclatural problems have been dealt with by a few words of explanation in the text. However, a few points call for more comment than appropriate in the Flora, and a few new combinations are needed in order to use a name for a relatively trivial form in what seems to be appropriate rank and position. (If such a form has never received a name, I feel under no compulsion to provide one, but when one exists, it might as well be used for forms that differ in some especially striking way from the usual state of a species.)
