One of the rarest and most beautiful of Ferns, with its 
undivided reniform fronds, and the curious crescent-shaped 
mass of sori, and the glossy ebeneous stipites. I am not 
aware that it has ever been gathered, but by the two eminent 
Botanists and S. American travellers just mentioned. Mr. 
Moore, in adopting the Genus Pterozonium , does not fail to 
remark, that it is “technically not very different from 
Gymnoyramme, but the aspect of the plant is so peculiar, that 
t le parallel contiguous receptacles, from which result a broad 
submarginal confluent sorus, may well be considered sufficiently 
di.tinetive. I am not aware that its habit is more peculiar in 
e genus than the Gymnoyramme figured in our preceding 
plate, which, nevertheless, Mr. Moore properiy Snslf 
that genus rather than adopt J. Smith and Fbe’s ffecistopteris
