Notwithstanding the figures above mentioned, this plant has 
not been satisfactorily and fully represented, because authors 
have been unacquainted with the pinnated state of it, and even 
Kunze only knew the divided frond as arising from cultivation, 
and only as laciniated and auriculated. Mr. Seemann’s speci- 
mens, however, are mostly pinnated, as represented in our left- 
hand figure. It is an extremely pretty species, the smallest of 
the Genus, and was supposed to be peculiar to Brazil till Mr. 
Seemann detected it in Veraguas, Isthmus of Panama, in 1849.
