A non-fertile margin always remains around the sorus. Regular close spacing of procarps on either side of the midline aids recognition of female gametangial blades (Fig. 3). Typically the vegetative cells which gave rise to carpogonial branches are more than one cell to the side of the central cell row, and about five cells apart on each side. The simplest stage showed two small cells overlying an apparently undifferentiated blade cell. Later arrangements ap- peared similar to those described for 5. repens (Yamada, 1971). One to several cystocarps can be found on one or both surfaces of the same blade (Fig. IB. F). Carpospores cannot be described as single and terminal, but were of graduated sizes with several shapes in short chains. Spermatangial mother cells also are recognized initially to either side of the central cell row. No reproductive cells, therefore were derived directly from cells of the primary cell row. Spermatangia were 2-5 broad, colorless, and overlay.
