L. cristata var. spinulosa bears a very strong resemblance both to 
Miss Roper’s and Mr. Little’s examples. I consider they are 
L. spinulosa Presl. in the form it usually grows in bushy ground 
on the Peatmoor of central Somerset, whence the earliest speci- 
mens in my herbarium are dated 1844. The distant lower 
pinnae are, at least in Somerset, characteristic of this fern ; but 
in Miss Roper’s specimens the pinnae are unusually conical in 
outline. See useful notes in Report for 1918 — 20, p. 127. —
