Covered Spores. The Liver- worts introduce us to the second and higher class of Cryptogams. The female flower is now called an Archegonium (14). It is no longer naked in its receptacle, like the spore of the Lichen (Fig. 27, p); but its vesicle, or nucleus, is cov- ered by a cellular sac which simu- lates a pistil (Fig. 27, a). This soon ruptures at top, to admit the anthero- zoids. Fig. Arohegoninm rj,j^ archegonia are usually enclosed in a of liiwervfOTi (Marchanlia poly- ._ ,i t â -n, i 't_ ⢠^i. mmpha):a.
