tri-pinnatifid (three times divided half-way to the midrib), their spear-shaped 

 leaflets, 2in. to oin. long and lin. broad, being again divided into pinnules 

 (leafits) similarly spear-shaped and cut down again into roundish or oblong- 

 segments of a thin, papery texture. The numerous oblong sori (spore masses) 

 become confluent in the centre of the segments. — Hooker^ Species Filicum, 

 v., p. 134. 



G. (Syngramme) Obtusifolia — Syn-gram'-me ; ob-tu-sif-oF-i-a (blunt- 

 leaved). Hooker. 



A stove species, of medium dimensions, native of Java, with simple, 

 (undivided) strap-shaped fronds Gin. to 9in. long, Jin, to |-in. broad, blunt 

 at the point, and very gradually narrowed at their lower jjart to a greenish, 

 naked stalk 2in. to oin. long proceeding from a creeping rhizome (prostrate 

 stem) ; they are of a leathery texture, smooth on both sides, and the narrow- 

 oblong sori (spore masses) are disposed near the mid vein. — Hooker^ Species 

 Filicum, v., p. 153, t. 299. 



G, OChracea — o-chra'-ce-a (ochre-coloured). A variety of Cr. tartarea. 



G. (Leptogramme) opaca — Lep-tog-ram'-me ; op-a'-ca (opaque), Sprengel. 



A very strong-growing, stove species, native of Java, Northern India, 

 Nepaul, and Khasya. Its fronds are several feet long, often 2ft. broad, and 

 borne on strong, glossy stalks IJft. to 2ft. long. The lower leaflets, often 

 1ft. long and Gin. broad, are divided into spear-shaped, closely-set pinnules 

 (leafits), which are cut down nearly to the rachis (stalk of the leafy portion) 

 below into close, oblong, slightly -toothed lobes of a soft, papery texture, and 

 naked on both sides. The oblong and irregular sori (spore masses) are 

 disposed close to the midrib. — Hooker^ Species Filicum^ v., p. 143. Beddome, 

 Ferns of British India, t. 238. 



G. (Eugymnogramme) Ottonis — Eu-gym-nog-ram'-me ; Ot-to'-nis 

 (Otto's), Klotzsch. 



This is a small-growing, stove species, native of Venezuela. Its bipinnate 

 (twice -divided) fronds seldom exceed 1ft. in length, including their glossy, 

 wiry, ebeneous (blackish) stalks. The leaflets are of a somewhat leathery 

 texture, and divided into nearly round, entire or slightly -cleft, naked
