Morphology Leaves

Leaves with (1)2–4(6) pairs of leaflets; petiole (0.3)2–7(10) cm long, petiole and rachis together 5–18 cm long, pubescent like the stem; leaflets (2.5)4–11(14) × (0.1)0.2–0.9(1.1) mm, linear to linear-oblong, or the lower ones sometimes ± elliptic, the apex acute to rounded or occasionally emarginate; upper surface glabrous, lower surface appressed-pubescent; stipules (3)4–12 × 0.3–0.8 mm (up to 17 mm long in var. >i>pilosa), linear, sometimes falcate.

Morphology Reproductive morphology Flowers

Flowers in lax terminal and axillary racemes up to 18(25) cm long, the upper branch racemes often subtended by only a bract instead of a foliage leaf and so forming a compound inflorescence, the branches usually forming an angle of about 45° or more, their axis slender (0.2–1 mm diameter) and usually rather flexuous and curving upwards, glabrous to shortly appressed-pubescent; bracts 2–4(5) × 0.2–0.5 mm, linear-triangular, rather inconspicuous and usually falling early; pedicels 3–6 mm long.

Morphology Reproductive morphology Flowers Calyx

Calyx 3–5.5 mm long, usually shortly appressed-pubescent with greyish hairs, or (var. >i>pilosa) with longer spreading hairs; upper teeth usually joined for most of their length to form an obtuse or acute triangle, or (particularly in var. >i>pilosa) free for more than half their length, the lateral teeth usually about equalling the tube.
