In the latter the archicarp branches, each branch bearing a spore sac.    From Wordnik.com.  [Elements of Structural and Systematic Botany For High Schools and Elementary College Courses] Reference

It is more slender than the archicarp, but otherwise differs little from it.    From Wordnik.com.  [Elements of Structural and Systematic Botany For High Schools and Elementary College Courses] Reference

The other branch (antheridium) grows up in close contact with the archicarp, and like it is shut off by a partition from its filament.    From Wordnik.com.  [Elements of Structural and Systematic Botany For High Schools and Elementary College Courses] Reference

The antheridium undergoes no further change, but the archicarp soon divides into two cells, -- a small basal one and a larger upper cell.    From Wordnik.com.  [Elements of Structural and Systematic Botany For High Schools and Elementary College Courses] Reference

There next grow from the inner surface of the covering cells, short filaments, that almost completely fill the space between the archicarp and the wall.    From Wordnik.com.  [Elements of Structural and Systematic Botany For High Schools and Elementary College Courses] Reference

Shortly before the fruit is ripe, the upper cell of the archicarp, which has increased many times in size, shows a division of its contents into eight parts, each of which develops a wall and becomes an oval spore.    From Wordnik.com.  [Elements of Structural and Systematic Botany For High Schools and Elementary College Courses] Reference
