Description:Excerpt from The Gametophyte of Botrychium Virginianum The fully developed antherozoid forms a spiral Of one and a-half turns and has the structure usual in the Filieinew. The cilia come Off from the attenuated, anterior end of the spiral. I could not decide, from the preserved examples which were the only ones I had the Opportunity Of examining under high magnification, the exact length Of the ciliary region. The antherozoids, like those of Ophioglossum pedunculosum described by Mettenius's, escape from the mother-cells while still within the antneridium. They swim about freely in its cavity, figure 28, a and 6: sometimes still retaining their protoplasmic vesicles and in other instances being already freed from them, figure 27, e' and e2. The spermatozoids make their way out by means Of an aperture formed by the disappearance of two superimposed cells of the outer wall of the antneria'ium. They do not escape all at once, as is quite generally the case, but seem to be voided in several swarms, at intervals, under undis covered conditions. The cavity Of the antherz'a'ium is filled with a thin gelatinous matrix, resulting, probably, from the disintegration Of the spermatocytic walls, figure 28, a and 5.
