Distribution and habitat: — Stryphnodendron moricolor has an extremely restricted distribution, occurring in non-flooded forests located near La Fumée Waterfall in French Guiana (Saül region), at altitudes from 200 to 400 m.

Conservation: —Data Deficient (DD) [AOO= 8.000 km 2, EOO not measurable]. Stryphnodendron moricolor has a very limited distribution range with only four collections from the 1980´s from two localities, however, the information currently available to us precludes a proper assessment of the conservation status of the taxon.

Phenology: —The species was collected with flowers in November, with immature fruits in March and with mature fruits in August.

Selected specimens examined: — FRENCH GUIANA. Saül : Grand Boeuf Mort Trail, 19 August 1987, fr., S. Mori et al. 18690 (P) .
