Hab. Pampayaco, Peru, Poeppig. Mount Guayrapurima, near Tarapota, Eastern 

 Peru, Spruce, n. 4686. Archedona, Ecuador, Jameson. — This fine species seems 

 peculiar to tropical western America, where it assumes very different forms; from 

 those with entire fronds, tapering at the base, through various pinnatifid states to 

 pinnate with a very broad base and triangular circumscription. Kunze's figure 

 represents one of the intermediate states, not at all pinnate. The largest pinna 

 on one of our specimens is nearly 11 inches long, and the superior margin is dis- 

 tinctly and obtusely lobed, the inferior quite entire. 



297. A. (Anisogonium) cordifolium, Mett. ; caudex rather 

 stout erect throwing out wiry roots, stipites 6 inches to a 

 foot and more long paleaceous especially towards the base, 

 fronds 6-8 inches to a foot long subcoriaceous simple and ob- 

 long acuminate entire cordate at the base and there subpin- 

 nato-lobate with oblong very obtuse segments and often 

 proliferous, or pinnate, pinnte 3-5 lateral ones horizontally 

 patent sessile or nearly so oi)long-ovate acuminate subob- 

 liquely cuneate at the base 3-4 inches long, terminal one 

 very large long-petiolate 6-8 inches long acuminate cordate 

 at the base, veins patent dichotomously fasciculate anasto- 

 mosing towards the margin, sori very long and narrow often 

 diplazioid and anastomosing, involucres very narrow brown 

 membranaceous. — Aspl. integrifolium, Metten. Asplen.p. 171.

Hab. Java, Blume, in Herb. Nostr., Zollinger, Lobb. Singapore, Wallich, n. 

 195; and Penang, Sir Wm. Norris. Isle of Leyte, Cuming, n. 307. — A very 

 handsome species, of which the entire-fronded state seems much more abundant 

 than the pinnated. 



298. A. (Anisogonium) alismafolii/m, Hook.; caudex short 

 rather stout and as well as the fascicled stipites 3-5 or more 

 inches long paleaceous with lanceolato-subulate crisped 

 scales, fronds subcoriaceous dark blackish-green from a span 

 (and then oblong-lanceolate acuminate acute at the base) 

 to 1 or 1 5 foot long and then ternate or pinnate with 7 or 

 more pinnee of which the lateral ones are 6-8 inches long by
