(6) Oh. leniiifolia, Sw.; Schk., Krypt. G-ew., I, tab. 1^5. 



Rhizome short-creeping, scaly. Stipes approximate, - + 5 — 20 ciri- 

 long, wiry, straight or flesuose, dark-brown, or purplish-black, polished, 

 naked or more or less sparingly and deciduously fibrillose, fibrilloso- 

 paleaceous towards the base. Fronds deltoid to lanceolate, + 5 — 20 cm. 

 long, 4 — 10 cm. broad, 3-pinnatifld or 3-pinnate. Pinnae in several or 

 numerous spreading or erecto-patent pairs, the lower the largest, opposite, 

 the following opposite or alternate, the largest 2 — 10 cm. long, deltoid. 

 Lowest posterior pinnalae largest, to 2% cm. long, cut down nearly or 

 quite to the rachis into very small, oblong, entire, crenate, sinuate or 

 pinnatifid segments to + 4 mm. long and 2 mm. broad, the free segments 

 often short-stalked and cuneate at the base, blunt at the apex. Texture 

 thinly coriaceous, firm; rachises like the stipe; surfaces naked or more 

 or less sparingly and deciduously fibrillose. Sori roundish or subcontinuous ; 

 indusium narrow, brownish, transversely oblong, more or less crenated or 

 toothed. — Ch. hirta Sw. differs from this in having the whole plant 

 densely hairy, commonly larger, with the lower pinnae very distant and 

 gradually much reduced.

Rhizome erect, short. Stipes 1 — 3 cm. long, those of the fertile fronds 

 the longest. Barren fronds 6 cm. more or less long, 10 — 12 mm. broad, 

 the rachis quadrangular and minutely paleaceous below, as is the stipe. 

 Pinnae numerous, sessile, to 6 mm. long by 1 '/2 — 2 mm. broad, obtuse, 

 crenate, narrowed at the base. Texture coriaceous; surfaces naked; veins 

 simple, 3—4 on a side. Fertile fronds paucipinnate, the pinnae stalked, 

 cordate, 2 — 3 mm. long by I'/j — 2 mm. broad, with the margin broadly
