texture and sub-sessile (almost stalkless), 4in. to 6in. long, lin. to 2in. broad, 

 egg-shaped and nearly entire (undivided). The sori (spore masses) are 

 continuous on both margins nearly to the extremity. This singular species 

 requires a porous, stony soil. — Hooker, Species Filicum, ii., p. 6, t. 79b.

A. Edgeworthii — Edge-worth'-i-i (Edgeworth's). A variety oi A. caudatum. 



A. elegans — e'-leg-ans (elegant). A form of A. cuneatuni. 



A. emarginatum — e-mar-gin-a'<-tum (notched at the end), Hooker, not 

 of Bory. A North American form of A. cethiopicum. 



A. excisum — ex-ci'-suni (bluntly cut), Kunze. 



This pretty, greenhouse species, native of Chili, though of smaller growth 

 and of slenderer habit, is closely allied to A. cethiopicum, and like that species 

 has also produced several distinct varieties. In the typical form the fronds, 

 6in. to 12in. long and 3in. to 4in. broad, are borne on stalks 2in. to Sin. 

 long, of a wiry nature and chestnut-brown colour, rising from a tufted 

 crown. They are furnished on each side with numerous flexuose (zigzag), 

 short leaflets, the lowest of which are slightly branched again ; their pinnules 

 (leafits) are about three lines broad, wedge-shaped at the base, while their 

 upper edge is rounded and bluntly lobed. The sori (spore masses) are large 

 for the size, of the plant, reniform (kidney-shaped), and situated in distinct 

 hollows on the lobes. — Hooker, Species Filicum, ii., p. 41.. Nicholson, Dictionary 

 of Gardening, i., p. 26. 



A. e. Leyi— Ley'-i (Ley's), Moore. 



In this variety, of garden origin, the fronds,, seldom more than 4in. long, 

 are very densely crested. — Nicholson, Dictionary of Gardening, i., p. 26. 



A. e. multifidum — mul-tif-id-um (much cut), Moore. 



This handsome, garden variety partakes somewhat of the character of 

 A. concinnum, both as regards the way in which its fronds are produced and 

 by the peculiar manner in which their stalk is covered by deeply-cut pinnules 

 (leafits) closely pressed against it. The fronds, of a drooping habit, are 

 quadripinnate (four times divided to the midrib), and their deeply-cut
