bipinnate (twice divided to the midrib) ; the leaflets, spear-shaped and of 

 a leathery texture, are cut down to the midrib into entire or slightly-toothed, 

 narrow-oblong pinnules (leaflts), Jin. to Jin. long, with inroUed edges, and 

 having about their own breadth between them. The lower surface is densely 

 clothed with a woolly substance of the same nature and colour as that observed 

 on the stalks. The oblong, thick sori (spore masses) at last cover the whole 

 under -side of the fronds, where they are hidden under the tomentum (down).

G. (Eugymnogramme) incisa — Eu-gym-nog-ram'-me ; in-ci'-sa (incised 

 or cleft). Linden. 



A stove species, native of New Grranada, ^vith fronds oin. to 4in. long, 

 IJin. broad, twice cut half-way to the midrib, and borne on wiry, ebeneous 

 (blackish), slightly hairy stalks Sin. to 4in. long. The spear-shaped leaflets 

 are cut down to a broadly -winged centre into oblong, entire (undivided) or 

 forked lobes of a somewhat leathery texture, on which the narrow-oblong 

 sori (spore masses) are disposed. — Hooker, Si^ecies Filicum, v., p. 134. 



G. (Eugymnogramme) insignis — Eu-gym-nog-ram'-me ; in-sig- -nis 

 (remarkable), Mettenius. 

 In this stove species, native of Central Brazil, the rachis (stalk of the 

 leafy portion of the fronds) is flexuose (bending to and fro). The fronds, 

 produced from a short, densely-scaly rhizome (prostrate stem), and borne on 

 short, chestnut-coloured stalks, are IJft. long, 2in. to olin. broad, spear-shaped, 

 and three or four times divided half-way to the midrib. The leaflets, distantly 

 placed and also spear-shaped, are 3in. to 4in. long, reflexed, and distinctly 

 stalked ; their pinnules (leafits), also stalked, are usually reflexed and blunt, 

 of a rigidly leathery texture, and with both surfaces hairy. The sori (spore 

 masses) fall short of the edge. — Hooker, Synopsis Filicum,, p. 516. 



G. (Selliguea) involuta— Sel-li'-gue-a ; in-vol-u'-ta (wrapped up, or rolled 

 inwards), Hooker. 



A stove species, native of Northern India, Ceylon, and the Solomon 

 Islands, also of Southern India, and, according to Beddome, very abundant 

 on the higher ranges of the Neilgherries and other mountains on the western 

 side of the Madras Presidency, usually growing there on rocks and trunks of
