near the margin, and reaching about halfway down the frond. 



Veins regular and internal. Increased by division. 



T. LINE ATA (Line-leaved). This is also from the West 

 Indies ; and is a remarkable, narrow, 

 long-frond ed Fern. Fronds simple, 

 2 feet long, and a quarter of an inch 

 broad, hanging down over the pot-edge ; 

 veins thinly strewed, but regular, and 

 placed within the centre of the leaf. 

 The fronds push up thickly from the 

 creeping rootstock : hence it is a very 

 suitable one for a thin rustic basket 

 to hang up in the stove. Increased 

 readily by division. This is some- 

 times known as Vittaria lineata. 



TEICHOMANES. 



For the derivation of the name of 

 this genus, and for an illustration of 

 the manner in which it produces its 

 fructification, see the Greenhouse divi- 

 sion. Until the last few years it was 

 thought impossible to grow these 

 Filmy Ferns ; but now there is a 

 large number which have been intro- 

 duced, and which may be looked upon 

 as established, but most of them are, 

 and will remain for some time, rare. 

 They are all found naturally growing 

 in the dark and humid recesses of the 

 forest, or in shaded situations where 

 they are kept moist by the spray from a waterfall, or any 

 similar situation where they can obtain the two great neces- 

 sities of their existence shade and a moist atmosphere.
