oogonial

A second portion of the oogonial branch is cut off just below the oogonium and constitutes the antheridium.

Their walls show in a less marked degree the reaction of the oogonial walls.

I have never been able to see any evidence of division in oogonial nuclei, and believe, with Hartog ( '92) and Dangeard (' 90), that it does not occur.

Mor - phologically sexual reproduction by oospores developed in typically globular oagouia, one or more from the entire protoplasm of each oogonium; antheridia on branches of androgynous or diclinous origin, very rarely on the oogonial branch, uniting with all, or with only a part of the oiigonia, or in several species wholly absent; when present, usually producing fertilization tubes which remain closed, at least in some species.

The outgrowths of the oogonial wall are only exceptionally rather long; and in the great majority of cases are not at all developed.

Oogonia not apiculate; antheridial branches always from the oogonial branches A. racbmosa.

This form, which appears to have been recognized only by its author, is said to differ from 8. monoica chiefly in its longer oogonial branches, which are coiled in a Digitized by Google WITH NOTES ON OTHBR SPBOIBS.

The antheridial branches arise from the main filaments or from oogonial branches, sometimes exclusively from one or the other, in other species from both.
