Group I. PTERIDOPHYTA. 



Some plants of this group, as the Warabi and Noki- 



shinobu (Fig. 51), have well developed large leaves ; some, 



as the Hikagenokatsura (Lycopodium clavatum) (Fig. 127)

leaves ; and others, as the Tokusa (Equisetum hyemale, var. 

 jcvponicum) and Sugina (Fig. 128), have minute verticillate 

 leaves. Those of the first kind are termed Filicince ; those 

 of the second kind, Lycopodince ; and those of the last, 

 Equisetmce. 



Pteridophyta are thus divided into the three classes 

 Filicinse, Lycopodinse, and Equisetinse.
