450 TREE-GROWING AND FORESTRY. [April 



*P. aqicilina var. tmdtifida. I have found this plant in but one of 

 our woodlands, where, however, it is tolerably plentiful. 



Cystoptcris fragilis. Not uncommon at high elevations. 



*C. fragilis var. cUntata. On a wall near Llandegai, Ijut not 

 abundant. 



Hymcnophyllnm. Wilsonii. Plentiful in two mountain woods. It

L. alpirnvni. 



L. Selago. 



L. Selaginoides.
