spear-shaped scales at the base. The fertile fronds are smaller, and are 

 borne on longer stalks. The sori (spore masses) are disposed in rows close 

 to the main veins, six to ten between the midrib and the edge.— Hooker, 

 Synopsis Filicum, p. 493. 



A. obliquum— ob-li'-qu-um (oblique). A variety of A. auriculatum,.

A stove species, native of Luzon, and one which in general appearance 

 somewhat resembles a diminutive form of A. aculeatum. Its fronds, 1ft. or 

 more long and 4in. to 6in. broad, are borne on stalks 4in. to 6in. long and 

 densely clothed with large, bright brown scales ; they are spear-shaped and 

 furnished with numerous pinnse (leaflets) of a leathery texture. The lower 

 leaflets are Sin. to 4in. long and fin. broad, and are divided into distinct 

 pinnules (leafits) furnished with blunt teeth. The sori (spore masses) are 

 disposed in two rows half-way between the midrib and the edge —Hooker, 

 Species Filicum, iv., p. 24, t. 221. 



A. OCellatum— oc-el-la'-tum (spotted). Synonymous with A. auriculatum.

 eyes), Hooker. 



This greenhouse species, of medium dimensions, is a native of New 

 Zealand. Its fronds, 1ft. or more long and 4in. to Gin. broad, are borne 

 on firm, straw-coloured stalks about 1ft. long, clothed throughout with 

 lanceolate (spear-shaped) scales of a dark brown colour. The pinnse 

 (leaflets) on each side of the midrib are numerous, Bin. to 4in. long by 

 ljin. broad, and of a leathery texture ; they are subdivided into spear- 

 shaped pinnules (leafits), cut down nearly to the rachis (midrib) into 

 oblong segments. The sori (spore masses) are disposed in two rows near 

 the midrib.— Hooker, Species Filicum, iv., p. 24, t. 228. 



A. Padleyanum— Pad-ley-a'-num (Padley's). A variety of ,4. angulare
