Haz. Rio Janeiro. Wm. J. Burchell, Esq. (n. 12.) 
I think it will be seen from the above character of De Candolle 
that the present plant belongs to his Genus Oligogyne ; notwith- 
standing some slight discrepancies, such as the included branches 
of the style in the discal florets, and the very different form of 
the pales. The former may be owing to the less advanced state 
of the flowers in our specimen; the latter can only be con- 
sidered of specific importance. Independent of this peculiarity 
in the palez, our plant does not well accord with the characters, 
slightly marked as they are, of any of that author’s 3 species, of 
which two are from Brazil and one from Mexico. ©
