Hab. N. India to Ceylon. — A common Indian plant, like A, sylvatiaim in texture, a 

 single lower pinna of this resembling a whole frond of that. We cannot in any way dis- 

 tinguish the New Caledonian A. sor&rium, Mett., of which the trunk is not known, from 

 the le!!s deeply lobed form of this, and have what appears to be the same from the Society 

 Islands.

1 in. br., cut down within a short distance of the rachis throughout into.inciso- 

 crenate linear-oblong segm., J in. br. ; texture herbaceous but firm ; colour 

 bright-green ; veins 4-5 on a side in the lobes ; lower sori 1^-2 lin. 1. ; invol.

248. A. (Dipl.) vestUum, Presl ; St. stout, erect, brownish, tomentose 

 throughout ; fr. 2-3 ft. 1., 9-18 in. br., with numerous pinnce on each side, the 

 lower ones 9 in. 1., 4 in. br., with numerous distinct subsessile pinnl., which are 



2 in. 1., 1 in. br., blunt at the point, and bluntly-lobed to a depth of |-J in., the 

 base narrowed suddenly or even cordate ; texture thinly herbaceous ; rachis 

 chafiy like the stem ; veins pinnate in the lobes ; veinlets 4-5 on each side ;

Hab. Philippines, Cuming, 336. — Trunk unknown. For the rest this resembles

 strong, erect, 1 ft. or more 1., livid, smooth, clothed towards the base with

 about 12 pinncB on each side, the largest 1 ft. 1., 4 in. br. ; jnnnl. numerous, 

 the largest 2 in. 1., ^ in. br. at the base, the point acuminate, the edge slightly 

 toothed, the base abruptly truncate on both sides ; texture subcoriaceous ; rachis 

 naked, livid ; veins about 6 in a group ; son linear, the lowest often 2 lin. 1. —
