THE BOOK OF CHOICE FERNS. 



G. perUYiana—per-u-vi-a'-na (Pem\dan). A variety of G. calomelanos. 



G. (Leptogramme) pilosa— Lep-tog-ram'-me ; pil-o^-sa (liairy), Martins 

 and Galeotti. 



A doubtful plant, of small dimensions, native of Mexico. Perhaps it may 

 be a small slender form of G. diplazioides, more liairy than u^u^l.— Hooker, 

 Species Filicum, v., p. 141. 



G. (Selliguea) pinnata— Sel-li'-gue-a ; pin-na'-ta (pinnate). Hooker. 



A stove species, native of Fiji, Queensland, and tbe Malayan Islands, 

 with fronds 1ft. or more long, nearly as broad, and simply pinnate (only 

 once divided to the midrib). The firm, upright, and glossy stalks are from 

 6in. to 12in. long, and the leaflets, 6in. to 9in. long and ^in. to lin. broad, 

 are gradually narrowed to both ends, and have their edge nearly entire; 

 they are of a leathery texture, naked on both sides. The oblong or linear 

 (narrow), irregular spore masses are often conMent.— Hooker, Species Filicum, 

 v., p. 151. 



G. (Leptogramme) polypodioides — Lep-tog-ram'-me ; pol-yp-od-i-o- 

 i'-des (Polypodium-like), Sprengel. 

 This stove species, native of Brazil, is a robust grower, producing from 

 a creeping rhizome (prostrate stem) fronds 1ft. long, 6in. to 9in. broad, and 

 bipinnatifid (twice divided half-way to the midrib). These are borne on 

 firm, glossy, naked stalks Gin. to Din. long, and are furnished with spear- 

 shaped leaflets cut two-thirds of the way down into sickle-shaped lobes 

 provided with a wing at the base. These lobes are of a soft, papery texture, 

 naked on both sides, and the narrow-oblong sori (spore masses) are disposed 

 down the centre of each lobe. — Hooker, Species Filicum, v., p. 140. 



G. (Ceropteris) pulchella— Ce-rop'-ter-is ; pul-chel'-la (fair). Linden. 



A very handsome, stove species, native of Venezuela, and one which 

 comes very near G. calomelanos peruviana, from which, however, it is readily 

 distinguished by its more upright habit and by the shape of its fronds, 

 which are borne on firm stalks 6in. to 9in. long, of a dark chestnut-brown 

 colour and silvery. The leafy portion of the frond is 6in. to 12in. long, 

 4in. to 6in. broad, oblong-triangular and tripinnatifid (three times di\dded 

 half-way to the midrib). The lower leaflets are the largest, and have their
