Leaves: Leaves compound. Alternate. Leaflets 3–7, thick, coriaceous, lowest pair strongly reduced, (0.2–)1.5–3(–4) cm long, rarely 1 or both reduced leaflets absent, normal leaflets 6–15(–36) cm long, (2.5–)3.5–9(–13.5) cm wide, lateral petiolules articulated only at base, 3–9 mm long, terminal petiolule twice articulated, at base and near leaflet, 8–30 mm long; lowest pair of leaflets stipelliform or, if expanded, then usually folded or strongly revolute, arising immediately below lowest pair of normal leaflets, normal leaflets oblong–elliptic, elliptic to broadly elliptic or sometimes broadly obovate. Leaflet apices obtuse to rounded. Base cuneate to rounded. Surfaces glabrous; conspicuously glandular punctate. Margins entire rarely weakly emarginate. Normal leaflets lateral veins usually 6–8 pairs, prominent, higher order venation forming a reticulate pattern. Rachis terete (cylindrical) or winged. Stipules absent.
