This evergreen, stove species, native of Mexico, somewhat resembles 

 a form of B. occide?itaIe, from which, however, it is totally distinct through its 

 leaflets, mostly alternate (not opposite, as those of B. occidentale), being sessile 

 (stalkless), and formuig a wing extending the whole length of the rachis 

 (stalk of the leafy portion). The fronds, of a deep green colour, are from 1ft. 

 to IJft. long, borne on scaly stalks, and produced from a creeping rhizome 

 (prostrate stem). The sori (spore masses) are disposed in a continuous line 

 on each side of and close to the midrib of the leaflets, and extend nearly to 

 their extremity. — Loive, Ferns British arid Exotic, iv., t. 35. 



B. (Eublechnum) unilaterale— Eu-blech'-num ; u-nil-at-er-a'-le (one- 

 sided), Willdenow. 



This very elegant, stove or greenhouse species, of small dimensions, native 

 of Tropical America, is usually met with in gardens under the name of 

 B. polyjjodioides. Its fronds, which while in a young state are of a beautiful 

 and conspicuous pink colour, are borne on slender stalks lin. to 4in. long, 

 scaly below, and produced from an elongated rhizome (prostrate stem) densely 

 clothed at the crown with narrow, pale brown scales ; they are lanceolate 

 (spear-shaped), 6in. to 12in. long, about 2in. broad, and furnished with 

 numerous leaflets of a thin, papery texture, usually toothed at the point, but 

 with the edges smooth or nearly so, the lower ones being dilated to a broad 

 base, shorter, and blunt. The sori (spore masses) are disposed in a hne close 

 to the midirih.— Hooker, Species Filicum, in., p. 45. Nicholson, Dictionary of
