G, (Eugymnogramme) marginata— Eu-gym-nog-ram'-me; mar-gin-a'-ta 

 (bordered), Mettenius. 

 This is a distinct, stove species, native of New Caledonia, and one of the 

 few members of the genus having simple (undivided) fronds. These fronds 

 are long-oblong, Sin. to 16in. long, fin. to IJin. broad, narrowed gradually 

 towards both ends at the base into a short stalk, with their edge slightly 

 bowed, showing a tendency to become sinuate (wavy) ; they are of a leathery 

 texture and have both surfaces naked. The sori (spore masses) are linear 

 (long and narrow). — Hooker., Sjjecies Filicum^ v., p. 127. 



G. Martensii — Mar-tens'-i-i (Martens's). .A form of G. calomelanos 

 chrysophylla. 



G. Massoni — Mas-so'-ni (Masson's). A form of G. calomelanos chrysophylla. 



G. (Eugymnogramme) Matthewsii — Eu-gym-nog-ram'-me ; Mat- 

 thews'-i-i (Matthews's), Hooker. 

 A stove species, of medium dimensions, native of Peru. Its fronds are 

 tri-pinnatifid (three times divided half-way to the midrib), 1ft. to IJft. long, 

 4in. to Sin. broad, oblong-spear-shaped, and borne on stalks 4in. to Gin. long, 

 of a dark chestnut-brown colour and clothed with dense, brown, deciduous 

 hairs. The leaflets, 2in. long and lin. broad, are cut down to the midrib 

 below into oblong, blunt leafits, with broad, rounded lobes of a leathery 

 texture and hairy on both sides. The sori (spore masses) are of a conspicuous 

 brown colour. — Hooker., Sjjecies F/'licum, v., p. 12<S, t. 290. 



G. Mayii — May^-i-i (May's). A sub-variety of G. calomelanos peruviana. 



G. (Selliguea) mexicana — Sel-li'-gae-a ; mex-ic-a'-na (Mexican), Baker. 



A stove species, native of Mexico and Guatemala, with simple (undivided) 

 fronds, produced from a wide-creeping rhizome (prostrate stem), clothed with 

 large, spear-shaped scales of a dull brown colour. These fronds, of a leathery 

 but flaccid texture, are sub-sessile (almost stalkless), 6in. to lOin. long, lin. 

 to l^in. broad, and sharp -pointed at their summit, but gradually narrowed to 

 the base. They are naked on both sides, and the few narrow-oblong sori, 

 which are not closely set, are disposed almost in one row on each side 

 of and not far from the midrib. — Hooker., Species Filicnm, v., p. 157.
