Of this species the writer has seen no positively authentic material. 
However, the Bolivian specimen of Kuntze (cited above and now in 
the herbarium of the New York Botanical Garden) is thus labelled 
in the hand of Hieronymus who doubtless had access at Berlin to the 
Brazilian type of the species collected by Sello. There is further- 
more at the Gray Herbarium a sketch of the species drawn by Klatt 
from Brazilian material. With both of these sources of information 
Rusby’s no. 1656 appears to be in agreement.
