3. W. glabella, Br. ; quite glabrous ; fr. linear, tapering a little below, pin- 

 nated ; jpinnce very remote towards the short St., all of them deltoid, very obtuse, 

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

 p. 64, 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 glabrous 

 form of W. hyperhorea ; and there Is a subglabrous Arctic American plant which closely 

 resembles W. ilvends. 



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

 long ferruginous hairs, mixed with very narrow, long, chaffy subulate scofc / 

 pinnae subcordate, dentate or lobato-dentate, scarcely pinnatifid (the rest as in 



W. h/perhorea'). 



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

 bottom ; Sikkimj alt. 14-16,000', Hooker, jU.- — Specimens from 3 different localities are 

 very uniform in the indament ; still, if W. glabella should prove a glabrous state of 

 W. Tiyperiorea, this may prove a var. in the opposite extreme, sericeo-tomentose in a 

 very high degree. 



§§ Physematium. Involucre larger than the sorus, not ciliated. Sp. 6-14. 



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

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

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

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

 mouth. — Hk. Sp. \. p. 60. Physematium, Kse. An. Pter, t. 27. W. fragilis, 

 JAebm. W. guatemalensis, Hh. Sp. 1. p. 61. t. 21. A. 



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

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

 are rarely so perfect as he figures them. 



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

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

 natifid ; pinnw 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. macroehlsena, Mett. Kuhn. Linn. 36. p. 126. 



Hab. Sea of Ochotsk, Dr. Clarice; China, Schottmuller, 191. 



7. W. eaiicasica, J. Sm. ; fr. lanceolate, a span long, glanduloso-hirsute on 

 the rachises and costie, firm-membranaceous, bipinnate ; prim, pinnae sessile, 

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

 pinnate ; lobes or ult. 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 opening with a 

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

 Hymenocystis, C. A. Meyer. W. fragilis ( Trev.) Moore, oldest name. 



Hab. Eare ; 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. I., 

 oblong, pinnated ; pinnce rather distant, alternate, sessile, from a broadish base, 

 oblong obtuse, pinnatifid not more than lialf-way down ; lobes short, rounded 

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

 near the sinus ; invol. lax, very membranaceous, globose, soon bursting with an 

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



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