Statut biogéographique : D'après Poncy (
in Barneby
et al. 2011): "Endemic of S Guyana , on forested slopes of Kanuku Mts. and nearby bushy areas of the Rupununi Savanna, although a few Brazilian collections were attributed to this taxon by Pennington ( 1997) (GU: 7). [...]
Inga brevipes is very closely related to
I. umbellifera of which it might be only a variety; pending more material, it is treated here as a separate species and considered as an endemic of S Guyana." L'unique collecte guyanaise déterminée comme telle semble donc plus que douteuse: mont Chauve, fourrés de savane-roche, 265 m, 13/04/1997, fruits. Arbuste. J.-F. Villiers & C. Sarthou 6099 (
CAY012876 [
Inga brevipes Benth. 1840, det. T.D. Pennington, 2008; non citée par Poncy
in Barneby
et al. 2011]).
