268 ASPLENIUM, § ANISOGONIUM. 



2 broad oblong-lanceolate acuminate slightly falcate entire 

 obliquely subcuneate at the base, terminal pinna the largest 

 10 inches long, veins oliliquely patent fascicled 2-3 times or 

 more forked anastomosing towards the margin, sori copious 

 narrow-linear frequently diplazioid often extending from the 

 costa to near the margin free (not anastomosing) parallel, in- 

 volucres extremely narrow. — Diplazium alisnifcfolium, Pr.

Hab. Malay Islands, Sorzogon, //<en/i:e. Luzon, Cuming, n. 116. — A very fine 

 and distinct species, bearing simple and pinnated fronds, often from the same 

 caudex. 



299. A. (Anisogonium) elegans, Mett. ; caudex short erect 

 with copious wiry roots, stipites tufted 5 inches to a span 

 long scaly at the base, fronds subcoriaceous from 6-10 inches 

 long and then entire broad-lanceolate much acuminated and 

 serrated towards the apex, or hastate with two spreading ob- 

 tuse lobes at the base, or 1-2 feet and more long pinnated 

 with several lateral (4-10) subopposite oblong-lanceolate ses- 

 sile pinncB often a foot to 16 inches long 2 inches wide sub- 

 cuneate at the base, terminal one long-petiolate larger than 

 the rest, veins subhorizontally spreading fasciculate twice or 

 thrice or more forked here and there anastomosing towards 

 the margin, sori linear-elongated near the costa but not ex- 

 tending to the margin, involucres rather narrow. — Metten.

Hab. Malay Islands; Luzon, Cnming, n. 276 ; and Leyte, n. 315 (large form, 

 Anisog. grossum, Pr.). Borneo, //. Low. Labuan, Thos. Lobb. — Allied to A. 

 alismtpfolium, but very dift'erent. Here the pinnae are serrated at the apex, and 

 the veins sparingly anastomose, and only near the margin. This anastomosing 

 venation is the only character that I know of to separate it from Aspl. (Eudipla- 

 zmia) fraxinifolium of Wallich, our n. 255. 



*** Fronds bi-tripinnate.
