The nucleus is at A^, a nuclear envelope at ne. Organelles of the cytoplasm include mitochondria (ni), dictyosomes (d), proplastids (pp), and endoplasmic reticulum (er). The surface of the protoplast and its relation to the extracellular wall (nu) are the points of major interest. It appears that the wall has been put down in layers, reflecting, possibly, phases of wall formation. The surface of the protoplast

FILICINEM LEPTOSPORANGIAT^ 317 Mottier (3) has recently examined the structure of the sper- matozoid in Struthiopteris. He could detect no cytoplasmic envelope investing the posterior coils, which seemed to be of exclusively nuclear nature. The vesicle showed a fine cyto- plasmic reticulum in which the larger granules were imbedded. The separation of the sperm cells begins at about the time the development of the spermatozoids commences. The muci- laginous walls stain now very strongly, and in

This shows an early stage in the development of the cell plate between two daughter cells of onion root meristem. The telophase nuclei are at A^ and a new- nuclear envelope has just reformed {ne). Long slender profiles of the ER, present in the interzone, appear noticeably shorter toward the plate region {cp), and at this level they reticulate and intermingle from the two sides to form a dense, irregular lattice of tubules. Within this structure, which has its origins in the marginal extensions of the ER, t
