of pmne decreasing in size. Lobes blunt entire, appearing acute 
on the fertile fronds from the revolute margins ; lateral veins 
alternate forked extending to the edge. Sori at length confluent, 
midway between the midrib and edge. Rhizome creeping.— 
Marshy and boggy places. P. VIL. VIIY. Marsh Fern. 
2. L. Oreopteris (Presl); fronds pinnate, pinne linear-lan- 
ceolate pimnatifid glandular beneath gradually decreasing from 
about the middle of the frond to near the root, lobes oblong, 
flat, sori marginal. — Aspidium Sm., E.B.1019. N. 187.— 
Fronds remarkably narrowed downwards, rising in a circle from 
a tufted rhizome, fragrant when bruised from the numerous 
glands on their under surface. Lobes blunt, entire ; lateral veins 
simple or forked. Height 2—3 feet. The indusium is often 
scarcely distinguishable—Mountain heaths. P. VII. Sweet 
Mountain Fern. 
3. L. Filiz-mas (Presl) ; fronds subbipinnate, pinnules obtuse 
and serrated, sori near the central nerve, lateral nerves forked.— 
Aspidium Sm., E. B. 1458. N. 198.—Fronds only slightly nar- 
rowed downwards and the lowest leaflet of considerable size, 
rising in a circle from a tufted rhizome. Pinnules a little com- 
bined at the base, usually very blunt. Stipes and rachis nearly 
glabrous, yellow, or densely clothed with purple scales. Indu- 
sium very persistent. Height 3—4 feet. incisa (Moore) ; 
pinnules more distinct rather acute, teeth patent lower ones with 
2 or 3 notches towards the end.—y. abbreviata (DC.) ; sori con- 
fined to the base of the pinnules, plant dwarf about 1 ft. high._—

Gloucestershire. P. VI. VII. Male Fern. 
4, L. cristata (Presl) ; fronds lmear-lanceolate subbipinnate, 
pinne short triangular-oblong pinnatifid, pmnules serrated the 
lowermost lobed and almost pimnatifid, lateral nerves of the lobes 
with several branches.—Aspidium Sm., EB. B. 2125. N. 203.— 
Fronds long and narrow, quite erect, from a tufted rhizome. 
Stipes very long, with scattered large brown blunt scales. Lateral 
nerves with numerous branches in the Holt plant, fewer in that 
from Oxton. Height about 2 feet—f. L. uliginosa (Newm.); 
“pimnules of fertile fronds oblong pomted deeply lobed somewhat 
aristate-serrate, lowest sometimes scarcely decurrent. The barren 
fronds resemble L. cristata; the fertile L. spinulosa’’ Moore. 1 
am very imperfectly acquainted with this plant.—Bogs and boggy 
heaths. Norfolk. Nottmghamshire. Cheshire. P. VIII. = E. 
5. L. spinulosa (Presl); fronds lmear-lanceolate bipinnate, 
pinuules oblong incise-pinnatifid, segments serrate spinose-mucro- 
nate, indusium persistent without marginal stalked glands, stipes 
clothed with broad roundish concolorous scales.—Aspidium Sm.,
