which are 1 i-2 in. 1., |-| in. hr,, truncate at the hase on the lower side, regularly 

 cut down throughout into distant, linear, curved pinnl. h lin. hr., the lowest on 

 the upper side larger and again pinnatifid or palmate ; texture coriaceous ; colour 

 pale-green; rachis thick, ilaccid, compressed upwards; one vein and sorus to 

 each segm., the latter marginal.— ^/{:. Sp. 3. p. 207. 



Hab. Mauritius and Bourbon. — Very near the preceding. 



168. A. (Darea) Belangeri, Kunze ; st. tufted, 4-8 in. 1., firm, erect, greenish, 

 naked ; /r. 12-lB in. 1,, 2-3 in. br., with numerous horizontal piiincv on each 

 side, 1-1^ in. 1., 3 in. br., rounded at the point, truncate at the base on the lower 

 side, regularly cut down throughout to a broadly-winged rachis into linear 

 erecto-patent pimil. J lin. br., with their own breadth between them, the lowest 

 usually once forked ; texture coriaceous ; colour pale-green ; rachis compressed ; 

 one vein and sorus to each segm., the latter marginal. — Hk. Sp. 3. p. 209. A. 

 Veitchianum, Moore. 



Hab. Malayan Peninsula, Java, Sumatra, Borneo. — A. Sampsmii, Hance, gathered 

 by Mr. Sampson about 100 miles west of Canton, of which our only specimen has lan- 

 ceolate fronds not more than 4 in. 1., under 1 in. br., and ovate-oblong pinn:« only cut 

 down to the rachis at the base, is probably a reduced form. It has been suggested that 

 this bears the same relation to tenerum that imequale does to lineatum, A. decorum, Kunze, 

 being a connecting link. 



1G9. A. (Darea) Thunlergii, Kunze ; st. tufted, 3-4 in. I., firm, naked, 

 greyish ; fr. 9-15 in. 1., 8-4 in. br., oblong-lanceolate, acuminate, with numerous 

 pinnce on each side, the largest 2 in. 1., 1 in. br., bluntish at the point, truncate 

 at the hase on the lower side, regularly cut down throughout to a broadly- 

 winged rachis into blunt piimls. 1 line br., the lowest larger and often again 

 pinnatifid ; texture herbaceous ; rachis compressed and flaccid upwards ; veins 

 and sori one in each segm. — Hk. iSp. 3. p. 208. A. auriculatum {Thunb.), Kuhn, 

 oldest name. 



Hab. Natal ; and a similar plant, with longer stems and narrower pinna and pinnules, 

 was gathered by G. Mann at Fernando Po.— Habit of the two preceding, but texture 

 diiferent. Perhaps a Dareoid form of ^. crcctum. 



170. A. (Darea) viviparicm, Presl ; st. tufted, 6-9 in. 1,, firm, erect, greenish, 

 deciduously fibrillose ; fr. 1-2 ft. 1., 6-8 in. br., with numerous close-placed 

 erecto-patent pinnce on each side, which are 4-6 in. 1., l|-2 in. br., cut down to 

 a compressed rachis into numerous pinnatifid pinnl., the lower segm. of which 

 are again forked ; ult. divisions j-f in. 1., j lin. br. ; texture herbaceous ; rachis 

 firm, erect, often viviparous ; one vein to each division ; sori solitary, marginal.

Hab. Mauritius and Bourbon. 



171. A. (Darea) Novce-Caledonice, Hk. ; st. tufted, 6-12 in. 1., firm, erect, 

 naked ; fr. 9-12 in. 1., 6-9 in. br., subdeltoid, tripinnate ; lower pinnce and jntinl. 

 deltoid ; segtn. rigid, scarcely flattened, | in. or more 1., distantly placed and 

 erecto-patent ; texture coriaceous ; rachis firm, erect ; veins solitary in each 

 segm. ; sori long, linear, marginal. — Hk. Sp. 3. p. 213. Ic. PI. t. 911. 



Hab. New Caledonia ; gathered by C. Moore, Vieillard, and Deplanche.

 lower pinnce ovate-deltoid, 6-8 in. 1., 2 in. br. ; sterile pi7inl. ovate-rhomboidal, 

 1 in. or more 1., i in. br., bluntly toothed and the base on the lower side 

 oblifjucly truncate;ytT^27(; ones the same size, but cut down to the rachis into
