The principal characters by which to distinguish this plant from other British Polypodies, are, that its fronds are both barren and fertile, and that the margins of the pinnules in the fertile frond are infiexed or con volute, covering the clusters of cap- sules. I have to acknowledge my obligation to the late Mr. Samuel Gibson, as well as to Miss Beever and Mr. Cruickshank, for fronds par- tially fruited and partially barren.

I have to acknowledge my obligation to the late Mr. Samuel Gibson, as well as to Miss Beever and Mr. Cruickshank, for fronds par- tially fruited and partially barren. The radicles are fibrous, numer- ous, tough, and adhere tenaciously to the earth or stones : the caudex is procumbent, extending itself hori- zontally, and producing a constant succession of fronds from its crown : this procumbent or horizontal posi- tion appears to me rather the result of age, or want of power to maintain an erect position, than of a tendency to a creei^ing habit. The fronds rise in May and June, and disappear at the commencement of winter : as before stated, they are of two kinds, fertile and barren, both being nearly triangular in form, and, like the frond of Adiantum Capillus-Veneris, they are composed of numerous, leaf-like, ultimate divisions: the pinnee, pin- nules, and ultimate divisions, are arranged alternately: the stipes is slender, smooth, pale green, and is generally much longer than the «frond, which is of a bright and de- licate green colour. The ultimate.
