In this feature, therefore, Microcachrys seems to be a transition form between Podocarpus and Dac- rydium on the one hand, and Saxegothaea on the other. In the development of the prothallial tissue, two cells are successively cut off, as among the Abietineae, but the peculiarity of the podo- carps is that these cells usually divide, resulting in extreme cases in a tissue of eight cells. A further peculiarity of this tissue is that the wall
