H. Lindigii — Lin-dig'-i-i (Lindig's), Baker. 



A greenhouse species, native of the Andes of Bogota, distinct through 

 its ample fronds being tripinnatifid (three times divided nearly to the midrib), 

 and borne on straw-coloured, smooth stalks. The leaflets, IJft. to 2ft. long, 

 are divided into sessile, ligulate pinnules (stalkless, strap-shaped leafits) Sin. 

 to 4in. long, cut down to a broad wing, and forming blunt, close, and 

 distinctly -toothed segments of a rigidly leathery texture, and green on both 

 sides. The sori (spore masses) are small and disposed near the midrib ; 

 they are partly covered with minute, smooth involucres. — Hooker, SynojJsis 

 Filicum, p. 454. 



H. macrocarpa — mac-roc-ar'-pa (large-fruited), Presl. 



A native of Bahia and British Guiana, with a trunk reaching 7ft. to 8ft. 

 in height, and stalks of a dark brown colour. Its ample fronds are bipinnate 

 (twice divided to the midrib) with leaflets 14in. or more long, 6in. broad, 

 stalked and pinnate below, pinnatifid only above. The abundant sori (spore 

 masses) form a single series, generally on the forking of a vein, half-way 

 between the margin and the midvein. — Hooker, Synopsis Filicum, p. 30. 



H. Melleri— Mel'-ler-i (Meller's), Baker. 



A native of Madagascar, with ample fronds three times divided to the 

 midrib ; these are furnished with oblong-spear-shaped leaflets 1ft. to 1 Jft. long, 

 and sessile pinnules (stalkless leafits) 2jin. to Sin. long, closely set and cut 

 down to the midrib into blunt, strap -shaped, toothed segments of a moderately 

 firm texture. The fronds are green on both sides and naked except on the 

 ribs above. The small and abundant sori (spore masses) are disposed close 

 to the midveins and partly covered by a smooth, depressed involucre of 

 a parchment-like texture. — Hooker, Synopsis Filicum, p. 456. 



H. Moorei — Moor'-e-i (Ch. Moore's), Baker. 



A very pretty and distinct species, native of Lord Howe's Island, with 

 fronds quaclripinnatifid (four times divided nearly to the midrib). These 

 fronds are borne on smooth stalks, and their rachises (stalks of the leafy 

 portion) are of a dull brown colour and covered with a meal-like powder 

 beneath. The oblong leaflets, Sin. to 12in. long, are furnished with stalkless.
