§ Cheiloplecton, JFee extens. Texture herbaceous or suhcoriaceous, and veins 

 clearly visible, the inmhtcre broad, and in most of the species rolled over the sorus 

 till full maturity. Sp. 1-11. 



■* Fronds lanceolate or ovate-lanceolate. Sp. 1-4. 



1. P. aiiriculata. Link ; St. tufted, 2-3 in. 1., flaccid, brijjht chesnut-brown, 

 sliglitly scaly ; fr. 3-0 in. 1., 1-H in. br., linear-lanceolate, with 12 to 18 rather 

 distant pinnre on each side, which are slightly stalked and broader in the barren 

 than in the fertile frond, and vary in shape from lanceolate-oljlong and entire, to 

 auricled at one or both sides at the base, or cut down nearly to the rachis in the 

 lower part into oblong lobes ; texture herbaceous ; rachis and both surfaces 

 naked ; invol. similar in colour and texture to the frond, broad and much 

 wrinkled.— //X.-. Sp. '2. p. 140. Hk. S Gr. Ic. t. 116. 



Hab. Cape Colony. 



2. P. Breweri, Eaton ; st. tufted, densely fibrillose at the base, 2-3 in. 1., wiry, 

 polished, chesnut-brown, nearly naked; fr. 2-3 in. 1., under 1 in. br., linear- 

 oldong, simply pinnate ; pinnce opposite, 6 to 8 on each side, the upper ones 

 ovate, undivided, sessile, the lower ones cleft down the centre nearly to the base 

 into two unef^ual halves, of which the lowest is the smallest, each the same shape 

 as the upper pinna?, and not toothed or further divided, the largest half about 

 \ in. 1., J in. br. ; texture thick, but scarcely coriaceous ; rachis naked, polished 

 like tlie stipe ; both surfaces pale-green, niked ; sori in continuous marginal 

 lines ; inool. broad, pale^ membranous. Eaton, Proc. Am. Ac. Art. & Sc. vol. 6. 

 p. 555. 



Hab. California ; gathered by Messrs. Brewer and Hillebrand. — Very near P. auricu- 

 lata, but the cutting of the pinnie is different, and also the venation. 



3. P. Seemanni, Hk. ; st. tufted, 1-2 in. 1., slender, wiry, naked, slightly scaly 

 at the base ; //'. .3-4 in. 1., 1-2 in, br., deltoid-oblong, bipinnatifid ; lower pinnae 

 not more than 1 in. 1., lanceolate-deltoid, cut down to the rachis below into a few 

 broad oblong blunt slightly-lobed pinnl.; rachis and both surfaces naked ; texture 

 herlKiceous, but the venation scarcely visible ; invol. narrow, membranous. — 

 HLSp.2.p. 141.^. 117. B. 



Hab. Mazatlan, Mexico ; gathered by Dr. Seemann. — Very like P. auriculata inhabit, 

 differing by its finer venation and narrower involucre. 



4. P. gracilis, Hk. ; st. scattered, slender, 2-3 in. 1., naked, straw-coloured or 

 pale-brown, polished ; fr. 2-4 in. 1., 1-2 in. br., ovate, hi- or tripinnatifid ; pinnae 

 lanceolate-deltoid, 1-2 in. 1., cut down to the rachis ; lower pinnl. sometimes again 

 sliglitly divided ; ult. segm. of the barren frond obovate, slightly crenate, of the 

 fertile one linear-oblong, terminal one much larger than the others ; texture 

 thinly herbaceous and flaccid ; rachis and both surfaces naked ; veins visible ; 

 invol. broad, continuous, membranous. — Hk.Sp. 2. p. 1.38. t. 133. B. 



Hab. Canada to Wisconsin, rare ; Siberia, Tibet, and N. India, at 9-10,000 ft. — This 

 has been cootounJed with C'rypfoyramme crispa, but is nut tufted, and is much mora 

 delicate in texiure. Fieris Sidleri of Gmtlin is the oldest name. 



** Frond deltoid. Sp. 5-11. 



5. P. pilosa, Hk. ; st. 6-9 in. 1., strong, wiry, brownish-black, more or less 

 clothed with small linear scales throu.chout ; barren and fertile fr. different, 

 the former deltoid, 1^ in. each way, cut down to within J in, of the rachis ; lowest 

 pinnce much the largest, deeply lobed, with the lobes again broadly crenate on tha 

 under side, the lower surface densely pilose, and the midrib scaly like the stipe ;
