TRICHOMANES. 



371 



T. Leprieurii — Le-prieur'-i-i (Le Prieur's). Synonymous with T. Prieurii. 



T. longisetum — long-is-e'-tum (having a long bristle). Synonymous with 

 T. ericoides. 



T. lucens — lu'-cens (shining), Swartz. 



A very distinct species, native of Tropical America, with rootstock scarcely 

 creeping. Its oblong -spear- shaped fronds, borne on stout, tufted stalks 2in. 

 to 4in. long and densely clothed with long, fine, rusty-coloured hairs, are 

 Gin. to 18in. long, 2in. to 4in. broad, and fully pinnate. The leaflets are very 

 closely set, often overlapping, are cut about half-way to the midrib, and are 

 of a delicately transparent nature. — Hooker, Species Filicum, i., p. 139, t. 41a. 



T. Luschnatianum — Lusch-nat-i-a'-num (Luschnat's). A variety of 

 T. radicans. 



T. macilentum— mac-il-en'-tum (thin), Van den Bosch. 



A native of Trinidad, Demerara, and the northern provinces of Brazil. It 

 is closely allied to T. Bancroftii, from which, however, it may easily be distin- 

 guished by the more divided nature of its fronds, which are 2in. to 6in. long, 

 and also by its creeping rhizome. — Hooker and Grevitte, Icones Filicum, t. 204. 



T. maximum — max'-iin-um (greatest), Blnme. 



This is a very strong-growing species, native of Java, Borneo, and the 

 Polynesian Islands. Its handsome, erect, egg-shaped fronds, 1ft. to ljft. long 

 and Gin. to 9in. broad, are borne on strong, erect stalks 3in. to 6in. long, 

 and are four times divided nearly to the midrib. The broadly- spear- shaped 

 leaflets sometimes measure Gin. in length and 2in. in breadth, and the leafits, 

 lin. or more in length, are cut down to the stalk into segments, which are 

 again deeply cleft, of a somewhat rigid texture, dark green in colour, and very 

 transparent. This species succeeds equally well on wood or on stone of 

 a porous nature, but requires a little higher temperature than most of the 

 Trichomanes in cultivation. — Hooker, Species Filicum, i., p. 137. Nicholson, 

 Dictionary of Gardening, iv., p. 81. 



T. mei folium — me-if-oF-i-um (Spignel-leaved), Backhouse. 



One of the most beautiful of all Filmy Ferns. Its noble plumes of tufted 

 fronds are fully 2ft. high ; they are spear-shaped and very finely divided,
