A male Guyana specimen examined, Jenman 4840 (BRG, K), previously identified by Heimerl as
Neea nigricans (Sw.) Heimerl and Neea jamaicensis Griseb., is the basis for the inclusion (now considered incorrect) of Guyana in the range of the Jamaican endemic Neea nigricans by Heimerl (1934). Similarly, Pulle (1906) cites Splitgerber 1030 (L) from Suriname, as Pisonia nigricans Sw. Despite the inference provided by the specific epithet "ovalifolia", the leaves of this species are very seldom oval or ovate.
