A. microphylla — mi-croph-yF-la (having small leaves), Klotzsch. 



A stove species, native of Caracas, with fronds ljft. long and bipinnate 

 (twice divided to the midrib) ; their rachis (stalk of the leafy portion) 

 is semi-terete (half-cylindrical), being convex on the back, plane upwards, 

 and closely hairy. The pinnae (leaflets) are 4in. to Sin. long, of thin texture, 

 spear-shaped, and spreading ; whilst their pinnules (leafits), about lin. long 

 and Jin. broad, are sessile (stalkless), pinnatifid (divided nearly to their 

 midrib), oblong, bluntish, smooth above and slightly hairy underneath, 

 especially below the middle, their costa (midrib) being clothed with egg- 

 shaped scales of a bright golden colour. The nearly round, small, Avhitish 

 sori (spore masses) are inserted on the middle of the back of the veins of 

 the fertile lobes. — Hooker, Synopsis Filicurn, p. 36. 



A. Miersii— Mi-ers'-i-i (Miers's), Hooker. 



This handsome, greenhouse species, native of the Organ Mountains, 

 Brazil, is of a particularly spiny nature. Its smooth fronds, of a somewhat 

 firm texture and bipinnate (twice divided to the midrib), are borne on stipes 

 (stalks) furnished with short but strong spines, which extend to the rachis 

 (stalk of the leafy portion of the frond). The primary pinna3 (principal 

 leaflets) are pinnate (divided to the midrib) to their summit ; and the 

 pinnules (leafits) thus formed are distinctly stalked, oin. to Gin. long, Jin. 

 broad, spreading, narrow spear-shaped, pinnatifid (divided half-way to their 

 midrib), terminating in a fine tapering point. The lobes formed by this sub- 

 division are egg-shaped and entire (uncut), and the rather copious sori (spore 

 masses) occupy their lower portion, being disposed half-way between the 

 midrib and the margin. — Hooker, Species Filicurn, i., p. 38. 



A. Moorei — Moor'-e-i (Moore's). Synonymous with A. Leichardtiana. 



A. myosuroid.es — my-os-u'-ro-i'-des (Myosurus-like), Liebmann. 



This species — discovered by Dr. Liebmann on the Mexican mountains 

 at 2400ft. elevation — is only known from dried specimens and from his 

 descriptions, from which we gather that the stem or trunk, 10ft. to 16ft. 

 high and 3in. to 4in. in diameter, produces large fronds with distinctly-stalked 

 leaflets ljft. to 2ft. long, and pinnules (leafits) 3in. to 3 Jin. long and Jin. 

 broad. — Hooker, Synopsis Filicurn, p. 38.
