This very pretty, stove species, closely allied to and intermediate between 

 A. Wagneri {A. decorum of commerce) and A. tinctum, is a native of the 

 Andes of Bolivia : it is of dwarf but elegant habit. The fronds, which are 

 abundantly produced from a close, tufted crown, and borne on exceedingly 

 slender, bla<3k, shining stipes (stalks) 4in. to Gin. long, have their leafy 

 portion of similar length ; they are deltoid (in form of the Greek delta, A) 

 and bipinnate (twice divided to the midrib). The numerous pinnules (leafits) 

 are fan-shaped at their summit, wedge-shaped at their base, and their outer 

 margin is lobed and finely toothed : they are sub-sessile (almost stalkless), 

 and when young are of a beautiful purplish-crimson, changing wdth age to 

 a light glaucous (bluish-green) tint, but even then tinged with pink ; so that 

 a good specimen is always more or less enlivened by a roseate hue. The 

 sori (spore masses) are round or slightly kidney-shaped, and are disposed 

 singly in the tips of the lobes. See Plate (for which we are indebted to 

 Messrs. J. Veitch and Sons). — Hooker, Synopsis Filicum, p. 474. Nicholson,

A. Seemannii — See-mann'-I-i (Seemann's), Hooker. 



This very handsome and totally distinct, stove species, also known under 

 the names of A. populifolium and A. Zahnii, is a native of Guatemala and 

 Brazil • it is of very peculiar growth, inasmuch as while in a young state the 

 plant only produces simple (undivided) fronds of extraordinary dimensions, 

 which are then heart-shaped, with an elongated point, and often measure as 

 much as 8 in. in breadth : they are produced from a thick, underground
