[The recent published works of Drs. Gray and Vasey have made necessary many changes in the nomenclature of our species. It has been suggested that these changes be deferred until the publication of a second edition of the " Flora," but this has seemed to be inadvisable, as it must be some years before a second edition can be brought out, if ever, and if we are constantly confronted by the old names we shall never become familiar with the new and correct ones.]
