Excerpt from Quarterly Journal of Microscopical Science, 1880, Vol. 20: With Illustrations on Wood and Stone A further difference between pro-embryo and embryo is now established, in that the next divisions in the embryo are perpendicular to that already formed, whereas in the pro embryo all the divisions are horizontal, and parallel to the first. In fig 24 the terminal cell of the proembryo is com mencing to divide as indicated b the condition of its nucleus, while in fig. 27 the second cel has just divided, and the last threads of protoplasm are still in contact with the new wall. We thus demonstrate that each cell of the pro-embryo divides, and its elongation is effected by intercalary growth. In some endospermous ovules the antipodal cells divide vigorously.
