7. A. eonfarme, Sw. ; rhizome woody, wide-creeping, densely clothed with large 

 lanceolate brownish membranous scales sometimes j^ in. 1., 1 Un. br. ; st. 1-12 in. 1., 

 firm, erect, stramineous, naked or slightly scaly ; fir. 2-9 in. L, \-2. in. br., the 

 point acute or blnntish, the base cuneate or spathnlate, the edge cartilaginous, 

 entire ; texlure coriaceous ; both sides naked or nearly so ; reins snbparallel, 

 usually once forked ; tarren fir. usually narrower than the fertile one, the edge 

 inflexed.— 5i. Sp. 5. p. 198. 



Hab. Mexico to Cluli and Brazil, Sandwich Isles, Samoa, Fiji, Java, Qneensland, Hima- 

 layas (np to 6,000 ft), Xeilgherries, CeyloD, Tristan d'Admha, Mascaien Isles, C^pe 

 Colony, St. Helena, Gninea Coast. — Fn>m this we cannot distaagolsh clearly^. Leper- 

 vanehH (Bory), A. didynanum (Ffe), A. laurifoUmn ^Thonars), A. angulatvm (Blurae), 

 A. impngsum, (F&), A. marginatum (WalL), A. obiusifolium ^Brack.), and A. ragans 

 (Mett.). The Polynesian A. Pegeeaae, Brack., is thinner and ^irker green than nsoal, 

 and narrowed downwards more giadnally ; A. alaiumj Ffe (Hk, Sp. 5. p. 204>, has a more 

 distinct haft to the frond; and the Sandwich Island.^, asmidum, Kanlf., and Andine 

 A. Gaymmm, ¥£e, and A. unitum, Bory {A. afme, AI. & 6.), and probably the Brazilian 

 A. mivaitum, FohL, ate small narrow-fronded varieties. Tiitaria acnstidunda, Hk. k. Gr. 

 t. 186, is an abnormal form, with the &mt in two sabmarginal lines. 



8. A. Wrighiii, Mett. ; rhizome wide-scandent ; st. 1-2 in. apart, 1-lJ in. 1^ 

 firm, erect, clothed throughout with OTate-acuminate membranous scales ; fir. 

 6-9 in. L, 1-lJ in. br., the point cuspidate, the lower part narrowed very gradu- 

 ally, the edge thickened, white, and crisped ; texture coriaceous ; both sides naked ; 

 midrib scaly in the lower part ; veins stout, immersed, subparaUel, usually once 

 forked ; fertile fir. much smaller, the edge entire and inJBexed. — Hh. Sp. a. p. 193. 



Hab. Coba, Wright, 965. — Perhaps a form of the last. 



9. A. flaeddim. Fee ; rhizome short-creepin?, woodv, the scales small, lan- 

 ceolate, dull-brown ; st. tufted, those of the barren frond Tery short ; fr. 6-12 

 in. L, ^1^ in. br., the point very acute, the lower part narrowed very gradually ; 

 texture subcoriaceous ; both sides qnite naked, colour dark-green, edge not thick- 

 ened ; veins not dose, simple or forked ; fiertSe fr. smaller than the barren one, 

 and on a distinct st. 3-4 in. L — Hk. Sp. 3. p. 204. A. IKarstenianum, Kze. 



Hab. Panama to X. BraraL — This is thinner in testnie than the preceding, and in the 

 shape of the frond is most like A. svmpUx on a larger scale, with senile barren &onds bat 

 long-stalked fertUe ones. A. oxyphyUum, Brong., appears to be a large form ; the Pem- 

 vian A. Ledderi, Mett differs only by its stoat wide-scandent rhiziame ; and a plant 

 labelled by Mettenins A. pallidum, Beyr., is tJunner and more glossy than the type, with 

 the costa and long stem of the ferdle freed ebeneoos. 



10. A. BurcheHii, Baker ; rhizome short, woody, the scales small, linear, dark- 

 brown ; rf. 8-12 in. 1., erect, nearly naked ; fir, 1-2 ft. 1., f-lj in. br., the point 

 very acute, the lower part narrowed very gradually ; texture subcoriaceous ; both 

 sides naked and glossy ; tans fin^ close, usually once forked ; fertile fr. much 

 smaller than the other. — ^A. punctulatum, M&t. MSS. (not L.). 



Hab. Brazil, BureheU, 5155. — Veiy near the last, di&ring mainly in the finer Teins 

 and long stem of the barren &ond. 



11. A. NorrisH, Hk. ; caud. stout, woody, the scales long, linear, dnU-brojm ; 

 harrenfr. sessile or nearly so, tufted, 12-18 in. L, f-1 in. br., the point blnnt, the 

 lower half narrowed very gradually ; texture coriaceous ; both sides nearly naked ; 

 fxins immersed, indistinct ; fertile fr. much narrower than the other. — St. 

 Sp. 5. p. 215. 



Hab. Penang, Str W. Norris, Mactier. — ?f ot unlikely identical with tiie Javan A . mdano- 

 slictum, Blnme. It is like jlacadum in the shape <^ the barren frond, but the textnre 

 is that of conforme and lat^aHum, and the fertile frond also is snbsessdle.
