234 . CHARACTEES Or TRIBES AND GENERA. 



Group 3. — Phegopteris vera. Vernation uniserial, sarmentose, 

 ejtifjcoiis or hyjiogeons. 



P. Dryopteris (Linn.) (vv.); P- Robertiana (Hofin) 

 (v V.) {Pohjpodium calcarewn, Sm.) ; P. vulgaris (Mett.) 

 (v V.) {Polijpodium Phegopteris, Linn.); P. aurita (/. Sm.) 

 (v V.) {Oyrnnogramma, Hook.) ; P. hexagonoptera (MicJix.) 

 (v V.) ; P. aquilina (Thoiiars) ; P. pteroidea {Klot.) ; P. 

 Keraudreiiianum {Gaud.) 



Obs. — In the " Synopsis Pilicum," P. divergens, P. effnsa, 

 P. lacknopodium, P. amplum, and others, are placed in the 

 indusiate genus Nephrodium. Although these have been 

 under my observation for a number of years in a living 

 state, and I have watched them carefully, I never found 

 the least trace of indnsia ; therefore, if indusiate specimens 

 are found in the herbarium, probably they represent dis- 

 tinct species, and allied to the multifid fronded species of 

 Lastrea.
