have closely allied plants from Queensland, Fiji, and the Seychelles, which need further 

 investigation. 



245. A. (Dipl.) Griffithii, Baker; st. 1 ft. L, naked, firm, erect ; fr. 12-18 in. 

 1., nearly as broad ; lower pinnae 9-12 in. L, 6 in. br., on stalks 1 in. 1. ; pinnl. 

 numerous, the longest 3 in. 1., in. br., cut down nearly to the rachis below ; 

 lobes erecto-patent, f in. deep, ^ in. br., deeply toothed, not contiguous ; rachis 

 smooth, flexuose, substramineous ; texture subcoriaceous, both surfaces naked ; 

 veins about 6 on a side in each lobe, with an oblong sorus on each, which is 

 less than 1 lin. L, touches the costa and scarcely reaches halfway to the edge. 

 Diplazium, Moore 2nd. Fil. p. 330. 



Hab. Assam, Griffith. This differs from the preceding mainly in the sori, and conies 

 near A. woodwardioides. 



246. A. (Dipl.) maximum, Don ; caud. erect ; st. 2 ft. or more 1., firm, erect, 

 scaly only at tiie base ; fr. several ft. 1., 2-3 ft. br., with numerous pinnce on 

 each side, the lowest 9-18 in. L, 4-8 in. br., with numerous distinct subsessile 

 pinnl. 2-4 in. 1., in. br., the edge more or less lobed, sometimes halfway 

 down ; texture herbaceous ; rachises and both sides nearly naked ; veins pinnate 

 in the lobes, 4-6 on a side ; sori medial, the lowest 2 lin. 1. A. diversifolium, 

 Wall., J. Sm. D. decurrens, Beddome, t. 220. 



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

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

 tinguish the New Caledonian A. sororium, Mett., of which the trunk is not known, from 

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

 Islands. 



247. A. (Dipl.) melanochlamj/s, Hk. ; st. strong, erect, 2 ft. or more 1., 

 smooth ; fr. 3-4 ft. 1., 2 ft. br., with numerous pinnce on each side, the lower 

 ones 9-12 in. 1., 4-6 in br., with numerous distinct sessile pinnl. 2-3 in. L, 



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. 

 narrow, glossy, quite black. Hk. Sp. 3. p. 260. 



Hab. Lord Howe's Island, S. Pacific, Macgillivray, 702, Milne, 36. Trunk 

 unknown. 



248. A. (Dipl.) vestitum, 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 

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

 lower sori of the lobes 3-4 lin. L, not reaching the edge. Hk. Sp. 3. p. 260. 

 2nd Cent. t. 46. 



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

 A . maximum, differing by its tomentose rachises. 



249. A. (Dipl.) latifolium, Don ; caud. erect, subarborescent ; st. tufted, 

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

 linear-crisped dark-brown scales; fr. 3-4 ft. 1., 12-18 in. br., subdeltoid, with 

 about 12 pinnce on each side, the largest 1 ft. L, 4 in. br. ; pinnl. numerous, 

 the largest 2 in. 1., f 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 ; sori linear, the lowest often 2 lin. 1. 

 A. dilatatum, Hk. Sp. 3. p. 258 (in part}.
