lower ones 2in. or more apart. The leaflets are 4m. to Gin. long, l^in. broad, 

 distinctly stalked, and while they terminate in a sharp point, they are some- 

 times broadly lobed below, their base being equally rounded on both sides 

 and their edge slightly toothed. Near their point the fronds, which are of 

 papery texture and of a deep green colour, are generally pinnatifid (divided 

 only half-way to the midrib). The irregular sori (spore masses) fall slightly 

 short of both midrib and edge. — Hooker, Species Filicum, hi., p. 241.

A greenhouse species, of medium dimen- 

 sions, native of Tavoy and Mishmee, in India, 

 and one of the few kinds belonging to the 

 section with simple fronds, of Avhich the Bird's- 

 Nest Fern (A. Nidus) is a good and popular 

 representative. Its fronds, 1ft. to ljft. long 

 and 2in. to 3m. broad, of a leathery texture, 

 are of an elongated spear-head shape being- 

 narrowed to a sharp extremity and gradually 

 below to a broad wing to the stalks, which 

 become very gradually narrower downwards. 

 The sori (spore masses) in most cases extend to 

 within a short distance of the edge. See Fig.
