TRICHOMANES. 367 



6in. to 12in. loBg, produced from a wide-creeping, slender rhizome, are 

 extremely delicate and membranous, and resemble thin, flat, much-branched, 

 green sea-weed. Their segments are narrow, smooth, either simple or forked, 

 and blunt. The plant thrives equally well on hard wood or stone. — Hooker,

T. fCBniculacetim — fcE-nic-ul-a'-ce-um (Fennel-like), Bory. 



This species, of medium dimensions, is a native of Mauritius, Bourbon, 

 Borneo, and Rockingham Bay, Australia. Its fronds, borne on slightly-tufted, 

 erect, wiry stalks 2in. to 4in. long, are 4in. to Sin. long, 2in. to Sin. 

 broad, erect, rigid, and broadly egg-shaped ; their lower leaflets, about IJin. 

 long, are cut down nearly or quite to the stalk, and are divided into 

 deeply-cleft leafits, which in their turn are cut into thread-like segments. — 

 Hooker, Species Filicum, i., p. 135. 



T. gemmatum — gem-ma'-tum (bud-bearing), /. Smith. 



A species having a strong, wiry rhizome covered with numerous long, 

 black, wiry fibres, from which are produced its upright, broadly egg-shaped 

 fronds, Sin, to 6in. long, lin. to 2in. broad, and borne on wiry stalks 

 lin. to Sin. long and winged above. The leaflets are cut down to a 

 narrowly-winged rachis into leafits with deeply-forked, thread-like segments. 

 This species is a native of South America and Malaysia. — Hooker, Species 

 Filicum, i., p. 1S5. Nicholson, Dictionary of Gardening, iv., p. 80.

This species, native of Mauritius, Bourbon, Malaysia, the Fiji Islands, &c., 

 is very handsome and one of the most distinct of the genus. Its fronds, 

 which are produced from a wide-creeping rhizome of a woolly nature, and 

 borne on strong, upright stalks 4in. to 6in, long, are egg-shaped and 

 distinctly quadripinnatifid (four times cleft almost to the rachis) ; they
