To study them in their natural position, thin longitudinal sections of the antheridial branch should be made.    From Wordnik.com.  [Elements of Structural and Systematic Botany For High Schools and Elementary College Courses] Reference

Fructification: ovate spores and tufts of antheridial cells attached to the lateral ramuli, which consist of minute, radiating, dichotomous beaded filaments.    From Wordnik.com.  [Scientific American Supplement, No. 384, May 12, 1883] Reference

In very few cases has anything representing prothallial development been observed; generally a small cell (the antheridial or generative cell) is cut off, leaving a larger tube-cell.    From Wordnik.com.  [Encyclopaedia Britannica, 11th Edition, Volume 2, Part 1, Slice 1] Reference

Reproduction by zoospores formed of the whole contents of a cell, with a crown of numerous cilia; resting spores formed in sporangial cells after fecundation by ciliated spermatozoids formed in antheridial cells.    From Wordnik.com.  [Scientific American Supplement, No. 384, May 12, 1883] Reference

Fructification: zoospores produced from the cell contents of the filaments; resting spores formed from the contents of particular cells after impregnation by ciliated spermatozoids produced in distinct antheridial cells.    From Wordnik.com.  [Scientific American Supplement, No. 384, May 12, 1883] Reference

Odspores averaging more than five; antheridial branches long A. oUgacarUha.    From Wordnik.com.  [Transactions of the American Philosophical Society] Reference

This is the only known case in this family of antheridia without antheridial branches.    From Wordnik.com.  [Transactions of the American Philosophical Society] Reference

Oogonia not apiculate; antheridial branches always from the oogonial branches A. racbmosa.    From Wordnik.com.  [Transactions of the American Philosophical Society] Reference

The male organs, or antheridia, are, when present, almost always borne on slen - der lateral antheridial branches.    From Wordnik.com.  [Transactions of the American Philosophical Society] Reference

The antheridial branches arise from the main filaments or from oogonial branches, sometimes exclusively from one or the other, in other species from both.    From Wordnik.com.  [Transactions of the American Philosophical Society] Reference

When the plants become old, these delicate antheridial branches often disappear, leaving the antheridia adhering to the oogonia without indication of their origin.    From Wordnik.com.  [Transactions of the American Philosophical Society] Reference

In case of the androgynous species, the antheridial branches begin to appear soon after the oogonial ones (Fig. 21); but the antheridia have usually been formed and come into contact with the oogonium before the basal wall of the latter has appeared.    From Wordnik.com.  [Transactions of the American Philosophical Society] Reference

It is not uncommon to see a young oogonium which has ceased its normal development and produced one or more smaller oogonia by proliferation from its surface (Fig. 23); and I have seen in A. A.ericana a fully formed oogonium, which, after the formation of its basal wall, had reverted to the vegetative condition, so to speak, and had given rise to an oogonial and an antheridial branch which had i-eached their full normal development (Fig. 24).    From Wordnik.com.  [Transactions of the American Philosophical Society] Reference
