The Position of Hepatics and Mosses 



The hepatics and mosses are therefore classified between 

 the lowest group of plant life (Thallophytes), bacteria, algae, 



fungi, etc., without stem, 



(Sport-Case leaves ' h and roots and the 

 m i mir. man spore-bearing plants which 



Vttl I ] H ft/ have well-developed stems, 



leaves and roots, such as ferns, 

 horse-tails, and lycopodiums, 

 (Fteridophytts). 



The genus Riccia has no 

 foot and no pedicel, simply a 

 spore case.

Hepatic sporophyte. The asexual generation. 



Fvnaria hygrometrica. A cross-section 

 from the pedicel of the sporophyte. The 

 cells through the centre of the pedicel are 

 modified to form rudimentary fibro-vascular 

 bundles, which one may interpret as fore- 

 shadowing the true fibro-vascular bundles 

 found in the sporophyte of ferns, etc. 



Equisetum sylvaticum with fertile 

 cone and whorls of branches. 



Male prothallium of a horse-tail with 

 antheridia. Sexual generation.
