LASTREA. 125 



almost triangular in outline,, and remarkably convex ; it has, 

 moreover, usually a dark green colour, often with a brownish 

 tinge. It is found in more exposed places than the normal 

 form, and. is not uncommon. 



Another is met with on the hills of the north of England ; 

 and this, which it has been proposed to call Lastrea collina, 

 is probably a distinct species. The form of its fronds is 

 ovate, drawn out to a long narrow point, and the pinnules, 

 which are obtusely ovate and have a broad attachment at 

 the base, have the serratures on their margin less spinulose 

 than in the common form. It was first noticed by the 

 Eev. Mr. Pindar in Westmoreland. 



Mr. Newman proposes to separate a form of this plant, 

 which differs in having its surface covered with glands, and 

 in the scales of the stipes being broader, under the name of 

 Lastrea glandulosa. Of its distinctness as a species we are, 

 as yet, unprepared to decide. It appears, however, to con- 

 nect L. spinulosa with dilatata, and is apparently the same 

 as had been previously named I/, maculata by Dr. Deakin. 



This species, though found in drier places than its near 

 ally spinulosa, is nevertheless partial to moisture, being 

 found in damp, shady hedge-banks and woodlands. It is 

 hardy, and easily cultivated.
