broad, sometimes elongated and rooting. They are furnished on each side 

 with numerous pinna? (leaflets) of soft texture, the lower ones fully 6in. long 

 by lin. broad ; the fertile pinna?, which are stalked and bowed, measure 2in. 

 to 3in. in length. — Hooker, Species Filicum, v., p. 259. 



A. (Chrysodium) reticulatum — Chry-so'-di-um ; re-tic-ul-a'-tum (netted 

 or veined), Kaulfuss. 

 A stove species, of botanical interest only and of small dimensions, native 

 of the Sandwich Islands. — Hooker, Synopsis Filicum, p. 421. 



A. (Photinopteris) rigidum — Pho-ti-nop'-ter-is ; rig'-id-um (stiff), 

 Wallich. 



In this handsome, strong-growing, stove species, native of the Philippines, 

 and, according to Beddome, also found in Singapore, Java, Labuan, Luzon, &c, 

 the fronds, several feet long and often 1ft. broad, are sometimes barren through- 

 out, but oftener they terminate in ten or a dozen very contracted fertile pinnte 

 (leaflets) 5in. to 12in. long, and covered with spore-cases on their whole length, 

 except on their costa (midrib) and on their slightly revolute margin. These 

 fronds are of a very leathery texture and glossy ; the barren pinna? are stalked, 

 jointed at the base, and from 3in. to 6in. long by Sin. to 3in. broad, their 

 extremity generally caudate (terminating in a tail) and curved upwards. The 

 stipes (stalks on which the fronds are borne), though short, are firm, nearly 

 as thick as a goose quill, and produced from a wide-scandent or long-trailing 

 rhizome (prostrate stem) of a woody nature and covered with fringed scales 

 of a brown colour. — Hooker, Species Filicum, v., p. 281. Beddome, Ferns of 

 British India, t. 69. 



A. (Chrysodium) rivulare— Chry-so'-di-um ; ri-vul-a'-re (growing by 

 the river-side), Baker. 

 A stove species, of small dimensions and of proliferous habit, but of very 

 little decorative value, native of Viti. — Hooker, Synopsis Filicum, p. 524. 



A. rufidulum — ru-fid'-ul-um (slightly reddish), Willdenow. 



A stove species, of small growth and very scaly appearance, of purely 

 botanical interest, native of Madagascar. — Hooker, Synopsis Filicum, p. 522.
