OF TREES AND PLANTS. 255 



The largeil lobes only are cut to the nerve. When the lobes arc 

 rounder, broader, and not fo deeply cut, it makes a variety diffe- 

 rent from the next to be defcribed. The groups of fructifica- 

 tions are larger, and in old plants entirely cover the back part of 

 the lobes. 



190. The Jlender Stone-Fern, ivlth ore/led folioks (o), is frequent In 

 the clefts of alpine-rocks. I have obferved it in the fiffures of 

 7>c&tf-rocks, and other places. It very much refembles the for- 

 mer. It differs from it by its narrow pinnules, and bifid acute 

 ferratures, ending in fpinules, like the fmall crejied Fern, and cut 

 to the very nerve ; alib by the fmaller number of fructifications 

 on the back of the folioles, which never cover them entirely. 



191. The fmall branched Female-Fern fp), is not uncommon irr 

 woods. It is a foot high. The branches are in pairs on the 

 ilalk, and gradually Ihorter. Thefe alfo are branched, and have 

 diftincl pinnules, firm, clofe, and long, marked with parallel 

 lines. The fructifications are in groups, and yellow. 



192. The great branched Male-Fern, with crefted pinnules (qj, a 

 beautiful fern, is not common. I have obferved it among the
