Sleumer's type of O. praecox {Pittier 12369) has the same collection number as that indicated by Pittier for an unpublished herbarium name. Gomphia guildingii Planchon, although treated as a synonym of Ouratea nitida (Swartz) Engl. (Mart. Fl. bras. 12(2): 310. 1876), is a distinctly diflferent taxon with much smaller leaves and nanowly racemiform inflorescences.
