and spined ; divisions at the apex of the frond narrow, their 
terminations acute ; all the divisions of the frond flat ; in- 
volucre nearly circular, 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 . — This very common fern has totally escaped the notice of Smith, 
Mackay, and Hooker and Arnott. Mr. Moore, in copying my figures 
of the palese and involucres of multiflora and spinosa, has unhappily 
transposed them. Babington is the only British author to whom I 
can refer.

“ The plant under the name of L. uliginosa in the 
Royal Gardens, corresponds with our A. spinulosum, 
a.” — Hook, and Am. 1. 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. 
Rliizoma tufted; vernation simply circulate, fronds erect, 
rigid, linear lanceolate, of two kinds, the fertile resembling 
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.
