T. Barklianum — Bark-li-a'-num (Barkly's), 



Baker. 



This species, which in the " Synopsis Filicum " 



is given as " a very interesting novelty, the discovery 



of which we owe to Sir Henry Barkly, the Governor 



of Mauritius, and Lady Barkly, who found it at Fig. 102. Portion of Fertile Frond 



„ • n J Ti/r v " • V ^x. °f Trichomanes Bancroftii 



Tamari Cascade, Mauritius, is one or the very ^^^^ ^^^ 



smallest known ; its little fronds, narrow-oblong, 



entire, and undulated at the edge, seldom reach Jin. in length, including 



their short stalks. — Hooker, Synopsis Filicum, p. 74. 



T. bicorne — bic-or'-ne (having two horns). Hooker. 



This species, which in some respects resembles T. alatum, is found 

 growing on logs or roots of trees, in the dense, moist forests of the Amazon, 

 and at St. Gabriel, Eio Negro ; it is also plentiful on decayed logs on the 

 Catingas, North of Brazil. Its strong rhizome is scarcely creeping, and its 

 egg-shaped fronds, 2in. to Sin. long and lin. to IJin. broad, are twice or 

 three times deeply cleft to a narrow-winged stalk. The remarkable feature in 

 this species is the involucre, which is sunk between the two horns as it were 

 of the apex of a segment. T. bicorne requires a warm temperature. — Hooker, 

 Icones Plantarum, t. 982 ; Second Century of Ferns, t. 82. 



T. bipunctatum — bip-unc-ta'-tum (two-dotted), Poiret. 



A distinct species, known also under the names of T. capillatum and 

 T. Filicula. It has a very wide range of habitat, being found in Mauritius, 

 Bourbon, Madagascar, Natal, Assam, Japan, Ceylon, Java, Borneo, &c. It is 

 provided with a wide-creeping, slender rhizome, from which its egg-shaped 

 fronds, borne on naked stalks lin. to 2in. long and slightly winged above, 

 are produced ; they are three times deeply cleft, and their rachis (stalk of the 

 leafy portion) is winged throughout. — Hooker, Synopsis Filicum, p. 81.
