Monographs Details: Palicourea nigricans K.Krause
Authority: Maguire, Bassett. 1972. The botany of the Guayana Highland--part IX. Mem. New York Bot. Gard. 23: 1-832.
Discussion:As noted above, this taxon has been confused with P. amapaƫnsis Steyerm., described above, as well as with P. longiflora (Aubl.) Rich. Although Krause describes the peduncles and pedicels as glabrous, the several specimens which I have examined show a minute puberulence on these parts. Also, specimens reveal the ovary as sparsely and minutely puberulent, although described by Krause as glabrous.
