on British Ferns. xix 



and spinecl ; divisions at the apex of the frond narrow, their 

 terminations acute ; all the divisions of the frond flat ; in- 

 volucre nearly cii'cular, its margins waved, not torn, nor 

 furnished with teeth or stalked glands ; clusters of capsules 

 circular, crowded, sometimes confluent, confined to the up- 

 per part of the frond. 



Common in damp woods in England. I have not seen 

 it from Scotland or Ireland. 



Obs. — Tills very common fern has totally escaped the notice of Smith, 

 Mackay, and Hooker and Amott. Mr. Moore, in copying my figm-es 

 of the paleae and involucres of multiflora and spiuosa, has imhappily 

 ti-ansposed them. Babington is the only Biitish author to whom I 

 can refer.

Aspidium spinulosum. Hook, and Am. 571, ad partem. — 

 " The plant under the name of L. uliginosa in the 

 Royal Gardens, corresponds with our A. spinulosum, 

 a." — Hook, and Am. I. c. The plant here referred to 

 as cultivated at Kew, is correctly named as my L. uli- 

 ginosa ; I mention this to show, from the evidence of 

 all parties concerned, that Aspidium spinulosum, a., 

 Hook, and Am., and my Lophodium uliginosum are 

 identical. 



Lophodium uliginosum, Newm. Phytol. iv. 371. 



Ehizoma tufted ; vernation simply circinate, fronds erect, 



rigid, linear lanceolate, of two kinds, the fertile resemhling 



those of the preceding, the barren those of the following 



species, pinnate ; pinnae also pinnate. 



Not uncommon ; bogs and boggy heaths, in company 



with the following species. 



Lophodium Callipteris.
