Type : FRENCH GUIANA. Saül, Monts La Fumée, 22 November 1982, Mori & Boom 15236 (holotype P 00077203! [transferred from CAY], isotypes NY!, P!)

Leaves with (1–)2(–3) pairs of pinnae, opposite; 3–4 pairs of leaflets, opposite to subopposite; petiolar nectary 1, lenticular-immersed; leaflets 7.3–14 × 4.5–6 cm, apex usually widely acuminate, sometimes obtuse, rarely round, margin flat to slightly undulate, subcoriaceous, discolor, glabrous on both surfaces, unilateral tuft of trichomes on lower surface absent. Sinflorescence a pleiothyrsus; cymulae of solitary, geminate to ternate spikes, spike 4.2–5.5 cm long; spike prophylls late deciduous, ca. 3 mm long. Flowers monoclinous, purplish, anther gland stipitate.

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) .
