scura, differing in the entire stipules and short peduncles ; 
P. obvallata is probably a Geophila, P. chrysorhiza,a Morinda, 
and P. Kolly, possibly, an Ixora; P. umbellata and P. triflora, 
if true Psychotria, are very different from any species known to 
me. P. angustifolia, G. Don, from Sierra Leone, is probably 
either a Pavetta or a Stylocoryne.
