pinnse (leaflets) are oblong-spear-shaped, ljft. to 2ft. long, furnished with 

 strap-shaped, stalkless pinnules (leafits) 4in. to 5in. long and fin. broad, the 

 segments (sub-divisions) of which are closely set, somewhat sickle-shaped, 

 blunt, slightly notched, of a sub -coriaceous (almost leathery) texture, bright 

 green and smooth on both sides. The small and abundant sori (spore masses) 

 are sub-costular (disposed close to the midrib of the fertile segments). — 

 Hooker, Species Filicum, i., p. 51. 



This species is very variable. The following are the most striking 

 amongst its known forms : A. Bongardiana of Mettenius, easily recognised 

 through its broader, entire (uncut) segments, which are rather glaucous 

 (bluish-green) underneath and furnished with scales ; A. intermedia, also 

 of Mettenius, with very broad segments and sori disposed farther apart ; 

 A. Veitchii of Baker, very distinct through its narrow, nearly pointed segments, 

 which are densely scaly on their midribs beneath, and which are also of 

 a much thinner, softer texture ; and A. vitiensis of Carruthers, distinguishable 

 from the species or common Viti plant above described through its more 

 rigid texture, as also through its sori being more crowded, and the 

 midribs of its segments being densely scaly underneath. — Hooker, Synojjsis 

 Filicum, p. 41. 



A. lurida — lu'-rid-a (lurid, dismal), Hooker. 



A stove species, native of Java, with fronds broadly spear-shaped, borne 

 on stipes (stalks) perfectly smooth, but with the rachis (stalk of their leafy 

 portion) rough and scaly below, very downy and scaly above. Their principal 

 leaflets are 1ft. long, furnished with pinnules (leafits) more than 2in. long, 

 Jin. broad, cut down to the rachis into numerous narrow segments of almost 

 leathery texture, dark green above, and densely scaly on the ribs underneath.

A. Macarthurii — Mac-arth'-ur-i-i (Mac Arthur's). Synonymous with 

 A. Leichard tiana . 



A. MacgllliYrayi — Mac-giF-liv-ray-i (Macgillivray's), Baker. 



A stove species from the Louisiade Archipelago. Its large fronds are 

 tripinnatifid (divided three times nearly to the midrib) and of a sub -coriaceous 

 (almost leathery) texture. Their pinnse (leaflets) are oblong- spear-shaped and
