^. L. uliginosa (Newm.); pinnules of fertile fronds oblong 

 pointed deeply lobed somewhat aristate-serrate, lowest some- 

 times scarcely decurrent. The barren and later fertile fronds 

 resemble L. cristata ; the earlier fertile L. spinulosa. The 

 lateral veins of the lobes are much less branched than in L. 

 cristata. I am very imperfectly acquainted with this plant, and 

 know of no good character by which to distinguish it from L. 

 cristata or h. spinulosa : it may pei-haps connect them. — Bogs 

 and boggy heaths. Norfolk. Notts. Cheshire. P. VIII. E. 



5. h. spinulosa (Presl) ; fronds linear-lanceolate bipinnate, 

 pinnules oblong incise-pinnatifid, segments serrate spinose-\a\\- 

 cronate, indusium persistent without marginal glands, stipes 

 clothed with broad roundish concolorous scales. — Aspidium Sm. 

 L. spinosa N. 209. — Fronds nearly erect; the lowest pinnas 

 equalling those that follow. Clusters mostly in 2 rows. — Marshy 

 places and wet woods. P. VIII. IX. 



6. L. rigida (Presl) ; fronds triangular-lanceolate bipinnate 

 glandular, pinnules oblong blunt lobed and serrate, segments 

 2 — 5-toothed not spinulose, lateral veins 3-fid, indusium per- 

 sistent fringed, stipes clothed with long pointed concolorous scales. 

 — Aspidium Hook., E. B. S. 2724. N. 191. — Fronds erect, lan- 

 ceolate with the lower pinnae rather short and triangular, or tri- 

 angular with the lower pinnje long ; upper pinnae narrow ; all 

 pinnate. Pinnules truncate below with a narrow attachment. 

 Stipes short, scaly. Covered with minute stalked glands. 

 Height 1 — 2 feet. — Ingleborough, Arnside Knot, and near Settle. 

 P. VII. VIII. E. 



7. L. dilatata (Presl) ; frond ovate-lanceolate bipinnate, pin- 

 nules pinnate or pinnatifid, segments acutely serrate spinose-mu- 

 cronate, indusium with marginal stalked glands, stipes clothed 

 with long pointed scales with a dark centre and diaphanous mar- 

 gin. — Aspidium Sm. L. multijlora N. 215. — Fronds arched, often 

 drooping, convex ; the lowest pinnae shorter than the following; 

 more or less clothed with stalked glands when young. Fronds 

 of young or starved plants often triangular, of older and perfect 

 ones never. Clusters scattered. The largest scales of the full- 

 grown plant should be examined.— 0. L. collina (Newm.) ; frond 

 lanceolate, pinnules ovate blunt bluntly mucronate-serrate. N. 

 223. — y. L. glandulnsa (Newm.) ; frond broadly lanceolate co- 

 vered with stalked glands beneath, scales of stipes "without the 

 dark centre." L. maculata Deak. Fl. Brit. f. 1612. — ^\i\'^oods, 

 banks, &c. 0. Westmoreland. P. VIII. IX. 



8. L. Fanisecii (Wats.); frond inarajrttZar bipinnate, pinnules 

 pinnate or pinnatifid, segments serrate spinose-mucronate, indu- 

 sium jagged at the edge, stipes clothed with long narrow lacini- 

 ate concolorous scales. — Nephrodium Foenisecii Lowe ! L. re-
