irtrjiij — )8. Oxton, Notts. Mr. Lloyd {hom Mr. Moore).— A species most 



^ distinct from any of the following, even in the outline of its fro7idy 



which is narrowed below. Whatever other botanists and collectors 



may have called Jspidium (or Lastrea) uliginosum, we have no 

 hesitation In considering the Oxton plant, communicated by Mr. 

 Moore, a slight var. of A. cristatum, as Mr. Moore himself has done. 

 ' ^> I He sends 2 states of ''spring and summer fronds;" the latter state 



y tie I is entirely covered with sori, to its very lowest pinna?, and is more 



3)& I deeply cut than the "spring" plant, which is really identical with 



many of the common forms of A, cristatum. All the forms are dis- 

 tinguished by the attenuated base of the frond, so as to give the 

 whole frond a linear-lanceolate or very elongated character ; the lower 

 pinnas short and "very broad at the base. At Kew Gardens a var. 

 of A. spinulosum has been received, under the name oi uliginosum. ,

 shire. — A beautiful, though very common, fern. 3 — 4 feet high; 

 its fronds growing in a circle. The var. j8. has a peculiar aspect 

 from the more distant and elongated pinnules, and is the A. affine 

 of Fischer from the Caucasus and Lenkoran. Mr. Borrer finds a 



variety, common in Devonshire, with more copious and brighter- 

 coloured scales on the stipes and rachis, and with a bright golden 

 yellow tinge on the whole frond: the same has also been found in 

 Yorkshire, various parts of Durham, and in Scotland.
