Excerpt from The Botanical Gazette, Vol. 43: January June, 1907The material for this study was collected at Darlington, S. C., where the plant grew normally and produced good seeds. Collee tions of young ovules were also made in Bonn, Germany, but they are here represented only in fig. 1.Our knowledge of the spermatogenesis of Cephalotaxus is confined to the work of strasburger (18) and of arnoldi Twenty seven years ago strasburger described the development of the embryo quite accurately for the stages observed, but he did not secure young proembryos. Arnoldi has described the gametophytes and proembryo, but he has overlooked certain interesting peculiarities and is in places not sufficiently clear.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
