often 1ft. long and 4in. to oin, broad, are divided into close, spear-shaped 

 pinnules (leafits), with oblong- spear- shaped segments and strap-shaped, nearly 

 entire lobes of a soft texture. The small and copious sori (spore masses), 

 disposed nearer the midrib than the edge, are covered with a thin involucre of 

 a fugacious nature. — Hooker^ Synopsis Filicum, p. 283. Nicholson^ Dictionary

This stove species, native of the Polynesian Islands, where it is common, 

 is one of the most striking as well as one of the most robust known ; it is 

 well suited for a large Fernery on account of its bold habit and its easy 

 culture. The handsome fronds, produced from a wide-creeping, stout rhizome 

 (prostrate stem), and borne on stout, brownish stalks 1ft. or more in length 

 and hairy, are IJft. to 2ft. long and Sin. to 12in. broad. The numerous 

 leaflets, 4in. to oin. long, are cut about one-third of the way down into sharp, 

 triangular, falcate (sickle-shaped) lobes of a somewhat leathery texture. The 

 sori (spore masses) are disposed in rows close to the midrib. — Hooker, Synopsis 

 Filicum, p. 290. Nicholson, Bictio?iary of Gardening, ii., p. 441.

A stove species, native of Jamaica, with fronds about 2ft. long. Sin. to

 with triangular fronds 1ft. to l^ft. long. Sin. to 12in. broad, borne on slender 

 stalks 6m. to 9in. long and slightly scaly at the base. The lowest leaflets, 

 which are much the largest, are oblong-triangular in shape, and are provided
