FILICES. 
oblong somewhat serrated all parallel upper ones gradually 
smaller. — E. B. 1149. Newm. 20. — Rhizoma brown, densely 
scaly, creeping. Fronds strapshaped. Sori large, on the upper 
part of the frond. Lateral veins of the pinnae with 4 branches 
of w T hich the lowest terminates in a sorus. Pinnae occasionally 
bifid at the end, sometimes deeply serrate or even (P. cambricum 
L.) doubly pinnatifid. — On shady banks, walls and old trees. 
P. VIII.— X. Common Polypody. 
2. P. Phegopteris (L.) ; fronds pinnate : pinnae linear-lanceo- 
late united at the base pinnatifid with linear-oblong blunt lobes, 
lowest pair of leaflets distinct turned back the rest pointing for- 
wards, sori marginal. — E. B. 2224. Newm. 24. — Rhizoma 
nearly black, wiry, slightly scaly, creeping extensively. Fronds 
triangular. Leaflets very acute, pointing forwards, rather hairy, 
connected by their whole width with the rachis ; the lowest 
pair quite distinct, with a minute stalk, standing forwards and 
pointing from the others. Lateral veins of the lobes simple, ex- 
tending to the margin. — Damp places, loving the spray of water- 
falls. P. VII.— IX. 
3. P. Bryopteris (L.) ; fronds ternate glabrous divisions pinnate, 
pinnae pinnatifid obtuse the uppermost nearly entire, sori mar- 
ginal.^ — E. B. 616. Newm. 26. — Rhizoma black, wiry, creeping, 
slightly scaly. Stalk slender, brittle. The three divisions of the 
frond loosely spreading, the middle one rather the largest. Sori 
distinct. Not at all glandular. — Shady mountainous places. 
P. VII. 
4. P. calcareum (Sm.) ; fronds subternate glandular -mealy : 
lower branches pinnate, pinnae pinnatifid obtuse the uppermost 
nearly entire, sori marginal. — E. B. 1525. — Very different in 
habit from the preceding and always covered with very minute 
stalked glands giving a mealy character to the surface. Frond 
not so decidedly 3-fid, the lower branches being much smaller 
in proportion to the middle one ; all the 3 erect, rigid. — On ex- 
posed mountain heaths or woods in limestone districts. P. VII.

3. Woodsia R. Br. 
1 . W. ilvensis (R. Br.) ; frond lanceolate pinnate hairy beneath. 
— Newm. 30. — Our plants appear to me to form but one species 
although they put on three different appearances as pointed out by 
Mr. Newman, viz. — x. W. ilvensis of authors ; fronds elongated, 
pinnae triangular with deep lobes. — /3. intermedia ; fronds lan- 
ceolate, pinnae oblong with more shallow lobes. W. ilvensis 
Hook. E. B. S. 2616. The Teesdale plant connects this with 
var. et. — y. W. hyperborea of authors ; fronds oblong, pinnae 
ovate with few rounded lobes. — E. B. 2023. — A very small 
plant ; fronds 1 — 3 in. long, hairy and scaly. Rhizoma tufted. 
— Exposed alpine rocks, very rare. a,. Ben Lawers. Mr. Dickson !
