It seeks to organize the vast amount of scattered material so that it may be available has been given to citations, so that the student may know the groups that have been investigated, and be put in touch with the original papers, the work is in no sense a compilation. The ground has been traversed repeatedly, for several years, by various members of the botanical staff and by numerous students, and their results have served to check current statements, as well as to contribute no small amount of new material.
