T. Colensoi — Col-en'-so-i (Colenso's), Hooker. 



This elegant, delicate-looking species, of a particularly slender nature, 

 was first discovered in the interior of the Northern Island, New Zealand, 

 by the Rev. W. Colenso, who states that he found it growing profusely 

 on the deep sides of a dark ravine on the banks of a rivulet, which 

 meandered through the dense and ever-humid forest of the mountainous 

 region between Waikare Lake and Rua Tahuna. Its wide -creeping, slender 

 rhizome is naked, and its oblong- spear- shaped fronds, 2in. to 4in. long, are 

 borne on naked stalks lin. long ; they are fully pinnate, with distant, 

 stalked leaflets cut down quite to the stalks, and very narrow segments. 

 This species grows best on porous stone. — Hooker, Synopsis Filicum, p. 85 ; 

 Second Century of Ferns, t. 79. 



T. crinitum — cri-ni/-tum (hairy), Swartz. 



This species, native of the West Indies and the Andes of Ecuador, is 

 very distinct on account of the hairy character of its foliage, the slender 

 stalks of its fronds being as hairy as the leaflets, which reach down very 

 nearly to the rachis and are cut about half-way down into narrow segments 

 with ciliated margins. This plant thrives best on wood. — Hooker, Species 

 Filicum, i., p. 131. Nicholson, Dictionary of Gardening, iv., p. 80. 



T. crispum— cris'-pum (curled), Linnaeus. 



According to Lowe, this very handsome and distinct species, native of 

 South and Tropical America and the West Indies, was first introduced into 

 the Royal Gardens, Kew, in 1851. Its fronds, 4in. to 12in. long and l£in. 

 to 2in. broad, are produced from a short rhizome and borne on strong, 

 wiry, woolly stalks 2in. to 6in. long ; they are spear-shaped, remarkably 

 transparent, and simply pinnate. The leaflets are lin. long, blunt, oblong, 

 spreading or even deflexed, and bear a few stiff hairs on their edges. 

 This species requires stove temperature, and prefers wood to grow upon.

T. curvatum — cur-va'-tum (curved). The plant known by this name is 

 identical with T. javanicum.
