SPORE-BEARING LEAVES. 



The Spore-bearing Leaves 

 are those, which bear 

 minute bodies called the 

 spores that answer to 

 seeds. (See Fig. 51.) 



Kinds of Spore-bear- 

 ing leaves. — Some spore- 

 bearing leaves may perform 

 only the reproductive func- 

 tion, as those of the 

 Zemmai (Osmunda regalis) 

 and Shishigashira (Lomcuria 

 Spicant) (Fig. 106) ; while 

 others may perform the 

 nutritive function at the 

 same time, as those of the 

 Nokishinobu (Fig. 51) and 

 Warabi.
