944 CRYPTOGAMIA ALGM. 



leaves are of an oval form, at a medium about 

 two inches long, and one wide, waved on the 

 margins, and either fmuated or largely dented ; 

 the dents all finely ferratcd, or rather ciliated 

 with a kind of fringe. They fometimes grow 

 oppofite to each other upon the ftalk, and 

 fometimes alternate, and are ribb'd in the mid- 

 dle throughout, the rib pinnated with oppofite 

 nerves. 



The leaves are often proliferous, their wide dents 

 ihooting out into other leaves, the lateral nerves 

 of the parent ferving for the middle ribs of the 

 offspring. 



The ftalk between the primary leaves is frequently 

 befet with fmall rudiments of junior leaves. 



The fru6lifications are thofe fine Cilia above- 

 mentioned, on the edges of the leaves ; for with 

 the aid of the microfcope, the feeds are evi- 

 dently difcern'd within them.
