522 100. FILICES. 



* Veinlets not knobbed but reaching the edge, all usually fertile , 

 clusters near the end of each. Rhizome with fronds at its 

 end. Stipes not jointed to rhizome. PHEGOPTERIS Fee. 



2. P. Phegop'teris (L.) ; fronds pinnate, pinnae linear-lanceo- 

 late united at the base pinnatitid with linear-oblong blunt lobes, 

 lowest pair of pinnce turned downwards, and forwards the rest 

 upwards, clusters marginal. E. B. 2224. H. F. 3. N. 115. 

 Pheg. polypodioides (Fee). Rhizome nearly black, wiry, 

 slightly scaly, creeping extensively. Fronds triangular. Pinnae 

 very acute, pointing upwards, rather hairy, connected by their 

 whole width with the rachis ; lowest pair quite distinct, with a 

 minute stalk, standing forwards and pointing from the others. 

 Dtimp places, loving the spray of waterfalls. P. VII. IX.

3. P. Dryop'teris (L.) ; fronds ternate glabrous, divisions pin- 

 nate, pinnae pinnatitid blunt uppermost nearly entire, clusters 

 marginal. j B. (316. H. F. 4. N. 123. Rhizome black, 

 wiry, creeping, slightly scaly. Stipe slender, brittle. The three 

 divisions of the frond loosely spreading, the middle one rather 

 the largest. Very young fronds resemble 3 little balls on wires. 

 Not glandular. Shady mountainous places. P. VI. VII.

4. P. Robertidwtm (Hoffm.) ; fronds triangular subternate 

 glandular-mealy \ lower branches pinnate, pinnae pinnatih'd blunt, 

 uppermost nearly entire, clusters marginal. H. F. 5. P. ca'- 

 careum Sm., E. B. 1525. N. 131. More erect and rigid than 

 the preceding, always covered with very minute stalked glands 

 giving a mealy character to the surface. Frond scarcely 3-iid, 

 the lower branches being much smaller in proportion to the 

 middle one ; all the 3 erect, rigid. On broken limestone ground.

*** Veinlets not knobbed, scarcely reaching the edge, simple or 

 branched, each bearing a cluster below its end or that of its 

 anterior branch. Rarely there is an oblique curved false in- 

 dusium. Stipes not jointed to rootstock. 



5. P. alpes'tre (Hoppe) ; fronds lanceolate bipinnate, pinncc 

 narrow-lanceolate with a broad base contiguous, pinnules widest 

 at their base acute pinnatifid with serrate lobes and branched 

 veinlets, clusters on upper half. H. F. 6. S. 49. Athyrium 

 (Milde). Fronds suberect, 1 3 ft. high. Much like Athyr. 

 Filix-fcemina. High mountain-valleys. P. VII. VIII. S.
