transverse ring — a character which is shared by all the species belonging to 

 the same section. — Hooker, Synopsis Filicum, p. 434. Nicholson, Dictionary

A. affinis — af-fi'-nis (related), Baker. 



A stove species, native of North Mexico. Its fronds are of a thin, 

 papery texture, and smooth on both sides : they are borne on naked stipes 

 (stalks) 6in. to lOin. long ; their barren portion is lanceolate (spear-shaped), 

 6in. to Sin. long, l£in. to 2in. broad, composed of eight or nine pairs of 

 spear-shaped or oblong pinnae (leaflets) Jin. broad, blunt, cuneate (wedge- 

 shaped) on the lower side at the base, nearly square on the upper side, finely 

 and irregularly toothed on the margins. The fertile portion consists of con- 

 tracted segments Sin. to 4in. long, borne on stalks fully 6in. long. — Hooker, 

 Synopsis Filicum, p. 525. 



A. (Coptophyllum) aurita— Copt-oph-yf-lum ; au-ri'-ta (eared), Swartz. 



In this stove species, native of Jamaica, the barren and the fertile fronds, 

 borne on separate stipes (stalks), are entirely distinct. The barren ones, on 

 firm, upright, slightly hairy stalks 2in. to 3in. long, are deltoid (in shape like 

 the Greek delta, A), Sin. to Gin. long, ljin. to 2in. broad, and bipinnate 

 (twice divided to the midrib) ; their lowest pinnse (leaflets), which are the 

 largest, are disposed on short footstalks, and are simple or occasionally 

 furnished with two roundish, sessile (stalkless), entire or slightly -toothed 

 pinnules (leafits) on each side : these are of a coriaceous (leathery) texture, 

 and have a glossy surface. The fertile fronds, borne on stalks 6in. to Sin. 

 long, form an interrupted panicle of contracted segments 2in. to 3in. long, 

 the lower branches of which are shorter than the others. — Hooker, Synopsis 

 Filicum, p. 435. 



A. (Coptophyllum) bipinnata— Copt-oph-yr-lum ; bip-in-na'-ta (twice 

 pinnate), Moore. 



A stove species, native of the West Indies. Its barren fronds are 2in. to 

 Sin, long, fin. broad, and borne on slender, naked stipes (stalks) lin. to 2in. 

 long : they are tripinnatifid (three times divided half-way to the midrib),
