Morphology Leaves

Leaves pinnate with 4–8 pairs of leaflets; petiole 2.5–6 cm long, petiole and rachis together 4.5–12 cm long, glabrous or with sparse appressed hairs; leaflets 1.5–3(4) × 0.6–1.2(1.5) cm, elliptic or oblong to obovate, obtuse to emarginate at the apex, ± cuneate at the base, the upper surface glabrous, the lower surface appressed-pubescent; stipules large and conspicuous, persistent, 9–17 mm long from point of attachment to apex, (6)7–14 mm broad, strongly cordate at the base with auricles on both upper and lower sides, the apex acute, the whole glabrous, not or scarcely ciliate, often turning blackish on drying.
