5in. broad. The leaflets are again divided into sessile (stalkless) leafits Jin. 

 broad, strap -shaj^ed, and cut down to a narrow wing. The sori (spore 

 masses), situated on the mid vein, are covered by minute, smooth, and fragile 

 involucres. — Hooker, Synopsis Filicum, p. 451. 



C. Beyrichiana — Bey-rich-i-a'-na (Beyrich's). Synonymous with Hemitelia 

 setosa. 



C. Boivini — Boi-vi'-ni (Boivin's), Mettenius. 



A strong-growing, stove species, native of Madagascar, of no particular 

 decorative value. — Hooker, Synopsis Filicum, p. 452. 



C. Brackenridgei — Brack-en-ridg'-e-i (Brackenridge's), Mettenius. 



A strong-growing, stove species, native of the Solomon Islands, and only 

 peculiar through its tripinnate (thrice -divided), ample fronds, of a dark 

 green colour on their upper surface and paler beneath, being borne on smooth 

 stalks of an uncommon greyish colour, and showing on their ribs singular 

 small, white, bullate (blister-like) scales. — Hooker, Synopsis Filicum, p. 452. 



C. Brunonis — Bra-no'-nis (Brown's), Wallich. 



A very distinct and peculiar, stove species, native of the Malay Islands, 

 and, according to Beddome, abundant in the Islands of Penang, Molucca, 

 and Borneo. It and C. Hookeri are the only species known with simply- 

 pinnate (only once-divided) fronds. These are large, and have their oblong- 

 spear- shaped leaflets, which are from Sin. to 14in. long, finely acuminate 

 (ending in a long, tapering point) and of a peculiarly glossy nature. — Hooker, 

 Species Filicum, i., p. 15. Beddome, Ferns of British India, t. 87. 



C. Burkei — Bur'-ke-i (Burke's). Synonymous with C. Dregei. 



C. camerooniana — cam-er-oo-m-a'-na (Cameroonian), Hooker. 



An African, greenhouse species, native of the Cameroon Mountains, where 

 it is found at elevations varying between 3000ft. and 4000ft. Its fronds, 

 4ft. or more in length and 14in. to 16in. broad, are borne on scaly stalks 

 Ift. to 2ft. long ; they are bipinnate (twice divided to the midrib), quite 

 smooth, dark green on their upper surface, paler beneath, and of a somewhat 

 leathery texture. The leaflets, 6in. to Sin. long and sessile (stalkless), are
