3. W. glahella, Br. ; quite glabvous ; fr. linear, tapering a little Lelovv, pin- 

 nated ; pinnce very remote towards the short st., all of them deltoid, very ohtuse, 

 cut into few (3-7) short-rounded or subcuneate, entire lobes. — Br. Ilk. Sp. 1. 

 p. G4, and in Fl. B. Am. 2. t. 237. 



Hab. America, from the hills of New York northward to the Arctic regions ; Arak- 

 amtchechene Island, Behring's Straits ; Norway, Tyrol, Carinthia. — Possibly a glaVjroua 

 form of IF. hyperborea ; and there is a subglabrous Arctic American plant which closely 

 resembles IF. ilvensis. 



4. W. lanosa. Ilk. ; fr. oblong pinnated, quite shaggy with most copious, soft, 

 long ferruginous hairs, mixed with very narrow, long, chaffy subulate sc«/c,s'; 

 pinnce subcordate, dentate or lobato-dentate, scarcely pinnatilid (the rest as in 



W. hi/perhorca). 



Hab. N. India; Mountains of Kamaoun ; alt. 11-12,000', Straclicy and Winter- 

 iottom ; Sikkim, alt. 14-16,000', Hooker, _/i^.— Specimens from 3 different localities are 

 very uniform in the indument ; still, if IF. glabdla should prove a glabrous state of 

 IF. Ii)iperborea, this may prove a var. iu the opposite extreme, sericeo-tomeutose in a 

 very high degree. 



§§ Physeraatium. Involucre larger than the sorus, not ciliated. Sp. 5-14. 



6. W. mollis^ J. Sm. ; fr. lanceolate pinnate, generally densely clothed, espe- 

 cially beneath, with soft jointed hairs, scarcely attenuated below ; pitince sessile, 

 from a broader base, oblong, obtuse, pinnatifid ; lobes approximate, oval or 

 subrotund, entire or crenate ; sori marginal ; invol. opening with jagged, circular 

 mouth. — Ilk. Sp. l.p. GO. Physematium, Kze. An. Pter. t. 27. W. fragilis, 

 Liebm. W. guatemalensis, Ilk. Sp. l.p. 61. t. 21. A. 



Hab. Mexico ; Guatemala ; Minas Geraes, Brazil ; Andes of Peru and Quito, Jameson, 

 McLean. — Our now copious specimens quite resemble Kunze's figure ; but the involucres 

 are rarely so perfect as he figures them. 



6. "W. ins7ilaris, Hance ; rhizome short ; scales 2-3 lin., oblong-lanceolate, red- 

 dish ; St. 1-1^ in., articulated near apex ; fr. oblong-lanceolate, l|-3 in. 1., bipin- 

 natifid ; pinnce 6-8-jugate, bluntly lobed, lower reduced ; texture firm ; both sides 

 pubescent ; sori submarginal, 1-4 to a lobe ; inv. large, membranous, persistent, 

 with ciliated lobes. — W. macrochliena, Mctt. Kiihn. Linn. 36. p. 126. 



Hab. Sea of Ochotsk, Dr. Clarke ; China, Schottniidler, 191. 



7. W. caucasica, 3. Sm.; fr. lanceolate, a span long, glanduloso-hirsute on 

 the rachises and costce, firm-membranaceous, bipinnate ; prim, jnnnce sessile, 

 nearly opposite, lanceolate, broadest at the base, acuminato-pinnatifid or again 

 pinnate ; lobes or idt. pinnl. oblong, acute, serrate ; sori large, 2 on each lobe or 

 pinnule, one on each side near the margin ; invol. globose, membranaceous, lax, 

 at first apparently entire with a central depression, at length o|)ening with a 

 contracted, depressed, irregular and somewhat 2-lobed mouth. — Hk. >Sp. l.p. 62. 

 Hymenocystis, G. A. Meyer. W. fragilis {Trev.) Moore, oldest name. 



Hab. Rare ; rocky places in the Caucasus, alt. 1,000-6,000 ft. 



8. W. elongata, Hk. ; glanduloso-pilose, especially above ; fr. a span to 1 ft. 1., 

 oblong, pinnated ; p>innce rather distant, alternate, sessile, from a broadish base, 

 oblong obtuse, pinnatifid not more than half-way down ; lobes short, roiinded 

 inciso-dentate, each bearing a sorus (rarely more) on the lower anterior veinlet, 

 near the sinus; z'hwo/. lax, very membranaceous, globose, soon bursting with aa 

 irregular opening at the apex. — Hk. Sp. 1. p. 62. t. 21. C. 



Hab. N. W. India, alt. 10,000 ft. ; Edrjeworth, Strachey, & Thomson.
