into entire and slightly sickle -shaped lobes of a soft, papery texture. The sori 

 (spore masses) are disposed nearer the edge than the midrib, — Hooker, Species 

 Filicum, v., p. 139, t. 292.

 Baker. 



A gigantic -growing, stove species, native of the Andes of Columbia and 

 Ecuador, with fronds bipinnatifid (twice divided half-way to the midrib), 3ft. 

 to 4ft. long, IJft. to 2ft. broad, and borne on strong, naked stalks l^ft. to 

 2ft. long and scaly only at the very base. The leaflets, Sin. to 12in. long 

 and l^in. broad, are cut three-quarters of the way down to the rachis (stalk 

 of the leafy portion) into oblong- sickle -shaped, finely -toothed, somewhat 

 leathery lobes. The linear sori (long and narrow spore masses) are disposed 

 close to the midrib. — Hooker, Synopsis Filicum, p. 377. 



G. (Selliguea) Hamiltoniana — Sel-li'-gue-a ; Ham-il-to-ni-a'-na (Hamil- 

 ton's), Hooker. 



A stove species, native of the East Himalayas, producing from a wide- 

 creeping rhizome (stem) of a woolly nature and covered with dull-brown, 

 linear (long and narrow) scales, fronds of two different forms : the barren 

 ones, Ift, long, 3in. to 4in. broad, spathulate (spoon-shaped), and are borne 

 on stalks 2in. to 3in. long ; while the fertile ones, 4in. to 6in. long and IJin. 

 broad, are borne on slender, naked stalks 1ft. or more long. Both fronds 

 are of a somewhat leathery texture, and the sori (spore masses) are disposed 

 in broad, continuous rows, one between each main vein. — Hooker, Species 

 Filicum, v., p. 160. Beddome, Ferns of British India, t. 239. 



G. (Eugymnogramme) Haughtoni — Eu-gym-nog-ram'-me ; Haugh'- 

 ton-i (Haughton's), Hooker. 

 This species, native of St. Helena, is closely related to G. cordata, from 

 which it differs principally in being more deeply cut and hardly at all scaly, 

 its dark green pinnaj (leaflets) being scantily provided with scales on their 

 under- surface only ; also in the nature of its sori (spore masses), which are 

 oblong, thick, and at last fill up nearly the whole of the under- surface. — 

 Hooker^ Second Century of Ferns, t. 7.
