Excerpt from The American Species of MarchantiaN 0 other liverwort has been so much discussed and described as M archantia polymorpha. According to Lindberg1 it attracted the attention of naturalists at a very early date and was known to both Aristotle and Theophrastus. Within more recent times it has repeatedly been the subject of morphological researches and has served in numerous text books as a typical representa tive of the thallose Hepaticae. Over eighty years ago Mirbel2 published the first extensive account of its morphology. He brought out the essential features of the thallus and of its various tissues and gave a clear description of the receptacles and the gemmae. Of the later works dealing with the morphology of the species those by Leitgeb, 3 Kny, 4 Ikeno, 5 and Durand6 may be particularly mentioned. The first two deal with the plant in a general way, very much as Mirbel's memoir did, although they include many original observations. The last two are much more specialized and deal with the cytology and development of the reproductive organs. Although M. Polymorpha itself has been treated so exhaustively the other species of the genus have been but little studied by morphologists.
