The species has been lately introduced from the Brazils 
by Mr. Sello, a german botanist, who has been employed 
some years in that country in the investigation of the ob- 
jects of this department of Natural History. The genus, — 
at present consisting of an only species, has been cha- 
racterized by Professor Sprengell from the absence of all 
appus or seed-crown and the peculiarly diminutive limb of 
the pistilliferous florets of the ray.
