The Genus Crepis

THE appearance of Babcock‘s monograph after four years delay in the press, due doubtless to the War, is an event of considerable importance, not only to botany but also to the biological sciences in the widest sense. Familiar as are parts of it to specialists, through the publication of numerous papers during a period of over twenty-five years, the collation of all this work in monographic form should bring it into the hands of a far wider circle of readers.The Genus Crepis By Ernest Brown Babcock.
