broad, are produced from a wide-creeping, strong, woolly rhizome ; they are 

 deeply cleft nearly to the broadly-winged stalk, and are borne on strong, 

 compressed stalks 2in. to 4in. long and winged above, their main rachis 

 (stalk of the leafy portion) being densely and the surface of the lobes slightly 

 hairy. This species requires a higher temperature than most of the Trichomanes 

 in cultivation. — Hooker and Greville, Icones Filicum, t. 10. Nicholson, 

 Dictionary of Gardening, iv., p. 81. Lowe, New and Rare Ferns, t. 63b. 



T. Kraussii — Kraus'-si-i (Dr. Krauss'), Hooker and Greville. 



This is a small, elegant, creeping Fern, native of Guiana and the West 

 Indian Islands, where it grows on trunks of trees. It is of upright habit, 

 with fronds lin. to 3in. long, oblong, narrower at the base than in their 

 centre, and cut down to a winged stalk into oblong, stalkless lobes that are 



deeply toothed or cleft and of a very transparent 

 nature (Fig. 104). — Hooker and Greville, Icones 

 Filicum, t. 149. Nicholson, Dictionary of Garden- 

 ing, iv., p. 81. Lowe, New and Rare Ferns, p. 164. 



T. Kunzeanum — Kunz-e-a'-nurn (Kunze's). A 

 variety of T. radicans. 



T. labiatum — lab-i-a'-tum (lipped), Baker. 



In this species, native of British Guiana, the 

 fronds are variable in shape, roundish and heart- 

 shaped at one or both ends, or somewhat egg-shaped 

 and narrowed at the summit ; they are of a dark 

 green colour, yet quite transparent, and the fertile

T. Lambert ianum — Lam-bert-i-a'-nurn (Lambert's), Hooker. 



This species, native of Peru, is a singular plant, for its narrow-oblong 

 fronds, borne on stout stalks 4in. to oin. long and densely clothed with long, 

 fine, reddish-brown hairs, are provided with very closely-crowded leaflets and 

 segments cut more than half-way to the rachis, which is densely woolly. —
