234 CHARACTERS OF TRIBES AND GENERA. 



GROUP 3. Phegopteris vera. Vernation uniserial, sarmentose, 



epigeous or hypogeous. 



P. Dryopteris (Linn.) (v v.) ; P. Robertiana (Ho/m.) 

 (v v.) (Polypodium calcareum, Sm.) ; P. vulgaris (Mett.) 

 (v v.) (Polypodium Phegopteris, Linn.); P. aurita (/. Sm.) 

 (v v.) (Gymnogramma, Hook.) ; P. hexagonoptera (HicJix.) 

 (vv.); P. aquilina (Thouars) ; P. pteroidea (Klot.) ; P. 

 Keraudrenianum (Gaud.) 



OBS. In the " Synopsis Filicum," P. divergens, P. e/usa, 

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

 indusiate genus Neplir odium. 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 indusia ; therefore, if indusiate specimens 

 are found in the herbarium, probably they represent dis- 

 tinct species, and allied to the multifid fronded species of 

 Lastrea. 



124. HYPOLEPIS, Bernh. (1806). 

 Hook. Sp. FiL (in part). 



Vernation uniserial, sarmentose. Fronds, 1 to 6 feet 

 high, bi-tripinnate, smooth, pilo-glandulose or aculeate. 

 Veins forked or pinnate, venules free, the lower exterior 

 branch sporangiferous. Receptacles terminal, punctiform, 

 Sori marginal, seated on the axis of an inflexed induseeform 

 crenule. 



Type. Hypolepis tenuifolia, Bernh, 



Illust. Hook, and Bauer. Gen. Fil., t. 67 B. ; Moore. 

 Ind. Fil., p. 27 A. ; J. Sm. Ferns Brit, and For., fig. 

 85 ; Hook. Syn. Fil., t. 2, fig. 24.

 generally large decompound, multifid fronds, rising from a
