T. digitatum — dig-it-a'-tum (having fingers), Swartz. 



This small species, native of Mauritius, Bourbon, and Java, is very 

 distinct, its fronds, irregular in general outline, being divided nearly to the 

 base or to a broadly- winged rachis into long, broadly-branched segments. It 

 succeeds best on porous stone. — Hooker, Species Filicum, i., p. 119. Beddome, 

 Ferns of British India, t. 301. 



T. dissectum — dis-sec'-tum (dissected). Synonymous with T. auriculatum. 



T. (Feea) elegans — Fe'-e-a ; e'-leg-ans (elegant). Budge. 



A most distinct species, producing from a tufted rootstock barren and 

 fertile fronds of totally different characters. The former, of a drooping 

 character, are pinnatifid, 6in. to Sin. long, 2in. broad, and borne on stalks 

 2in. to Sin. long ; they are broadly spear-shaped, with leaflets nearly horizontal, 

 crowded, somewhat sickle- shaped, finely toothed along their edges, and 

 frequently terminating in a tail-like process proliferous at the extremity. The 

 fertile fronds, 6in. to 12in. long and of erect habit, are extremely narrow and 

 undivided, seldom ^in. broad, and fringed on each side with coarse, hair-like, 

 slender spore-receptacles. The plant is a native of Tropical America, from 

 Trinidad and Mexico southward to Peru. — Hooker, Species Filicum, i., p. 114.

T. elongatum — e-long-a'-tum (lengthened). A variety of T. rigidum. 



T. ericoides — er-ic-o-i'-des (Erica-like), Hedwig. 



A very singular plant, native of Borneo, Java, Samoa, and Bourbon, and 

 requiring a higher temperature than most other species. Its curious-looking 

 fronds. Sin. to Sin. long, 2in. to 2 Jin. broad, are produced from a strong, 

 wiry rhizome of a woolly nature, and borne on upright stalks lin. to 4in. 

 long, wiry, and not at all winged. Their leaflets and leafits spread in all 

 directions and are not at all flattened. T. longisetum is another name for 

 this species. — Hooker, Synopsis Filicum., p. S7. 



T. erosum — e-ro'-sum (bitten). Synonymous with T. muscoides. 



T. exsectum — ex-sec'-tum (cut out), Kunze. 



A lovely species, native of Juan Fernandez and Southern Chili, where 

 it is said to grow hanging from the roofs of damp caverns. The fronds,
