316 MR. J. MIERS ON THE HIPPOCRATEACEZ OF SOUTH AMERICA. 
Velloz's drawing sufficiently well represents the typical species from Rio de Janeiro, 
where I also collected the same plant, in flower only ; but the very large fruit obtained 
in the same locality by Bowie and Cunningham quite corresponds with Velloz's drawing. 
I found another species on the Corcovado, in flower and fruit, both examined by me in 
the living state, when the analytical drawings, still preserved, were made: these afford 
ample means, from which the following generic character is constructed.
