described the form with simple pinns. A. cyrtopteron and Jlabellatum of Kunze have 

 them deeply lobed and pinnatifid, especially in the lower half, whilst the plant called 

 rhlzophorum by Swartz is fully bipinnate, and A. rachirhizon, Raddi, and A. amaljile, 

 Liebm., have distinctly separated oblong-rhoniboidal pinnules again deeply cut into 

 narrow segments. 



76. A. anisodojiticm, Presl ; st. tufted, firm, erect, grey, naked or slicrlitly 

 fibrillose ; /)'. 12-18 ia. 1., 4-0 in. br., with numerous horizontal or suljfalcuto 

 sessile j[>v'«H« on each side, whicli are 2-3 in. 1., \ in. br., .the point acuminate, 

 the edge inciso-crenate, the base on the upper side auricled and narrowed rather 

 obliquely, on the lower side obliquely truncate ; texture subcoriaceous ; rachis 

 firm, erect ; veins oblique, mostly once branched ; sori jjarallel, in 2 regular rows, 

 reaching nearly from the midrib to the edge. — Ilk. Sp, 3. p. 153. 



Hab. Java and Philippines. 



77. A. contiguum, Kaulf. ; st. tufted, 6-9 in. 1., firm, erect, chesnut-brown, 

 naked ; fr. 12-18 in. 1., 4-6 in. br., with 20-30 horizontal subfalcate pinnce on 

 each side, which are acuminated at the apex, the edge more or less sometimes 

 deeply iuciso-serrated and slightly lobed, the base narrowed suddenly, and some- 

 times auricled on the upper, ol)lique!y truncate in a curve on the lower side ; 

 texture subcoriaceous ; rachis firm, naked or slightly villose, chesnut-coloured ; 

 veins oblique, obscure ; sori close, copious, falling considerably short of the 

 margin.— //X-. Sp. 3. p. 156. t. 194. 



Hab. Sandwich Islands, Philippines, Neilgherries. — The alliance of this and the pre- 

 ceding is with A. falcatum, but the fronds are narrower, and the sori more uniform. 



78. A. hirtum, Kaulf. ; st. tufted, 2-4 in. 1., strong, erect, brownish, deciduously 

 fibrillose'; fr. 12-24 in. L, 4-8 in. br., with very numerous horizontal jnnnoe on 

 each side, which are 2-3 in. 1., j-f in. br., the point acuminated, the edge broadly 

 not deeply toothed, the base on the upper side conspicuously auricled, on the 

 lower side rather suddenly but obli(iuely narrowed ; texture coriaceous ; rachis 

 dark-coloured, strong, more or less fibrillose ; veins oblique, inconspicuous ; sori 

 in 2 regular rows, w^hich fall considerably short of the edge. — Hk. Sp. 3. p. 149. 

 t. 191. 



Hab. Mauritius, Madagascar, Seychelles, Malayan Peninsula and Islands, Hong-Kong, 

 the Philippines, Ladrones and Solomon Islands. — This has the simple veins and regular 

 sori oi A. lineatum and longissimum, but the pinnEe are unequal-sided. A. induratum, 

 Hk. 2ud Cent. F. t. 61, from Fiji, seems to be only a small form of this with blunter 

 pinnte. A. jjcUuciduyn, Lam., is apparently this species j and if so, that name (a very 

 inappropriate one) is the oldest. 



79. A. hastntum, Klotzsch ; st. tufted, 4-6 in. 1., firm, erect, greyish, scaly 

 below ; fr. 6-12 in. 1., 3-4 in. br. ; oblong-lanceolate, with 8-12 horizontal 

 subsessile pinnae on each side, which are lc^-2 in. 1., about | in. br., the 

 point acuminate, the edge deeply crenato-dentate throughout, the two sides 

 unequal, the upper one narrowed at nearly a right angle, the lower one very 

 oblique ; texture subcoriaceous ; rachis compressed ; veins obscure, very 

 oblique ; sori distant, falling short of both edge and midrib. — Uk. Sp. 3. 

 p. 116. t. 172. 



Hab. Columbia and Ecu.ador. — A.frar/ranSfllk. Ic. t. 88, is a small Andine form with 

 a winged rachis. This is very near A . firnvxra and auriculatiim, but is thicker in texture. 



80. A. enatuin, Brack. ; st. tufted, 6-8 in. 1., firm, erect, naked ;fr. about 

 1 ft. 1., 4-5 in. br., with 9-15 jL>fyi7«ce on each side, which are 2-3 in. 1., ^-| 

 in. br., the point acute, the upper part bluntly crenated, the two sides very 

 une(pial, the upper rounded or narrowed suddenly at the base, the lower
