Indigofera zenkeri

Erect bushy herb 0.5–2 m. tall, covered throughout, but not densely, with white appressed or spreading biramous hairs and also, almost everywhere, with erect multicellular glandular hairs up to 2 or even 3 or 4 mm. long on the stems and 1 or 1.2 mm. on the fruits, but shorter on the inflorescences, flowers and leaves, where they occur on the leaflet-margins as well as on the rhachis. Stipules green, linear-lanceolate, spreading, up to 4 mm. long; leaf-rhachis up to 8 cm. long, including a petiole which is usually longer than the basal leaflets; leaflets up to 15 or 19 or rarely 23, elliptic, 1.5–2.5 times as long as wide, up to 12 mm. long and 7 mm. wide. Racemes 10–20-flowered, usually rather longer than the subtending leaf; peduncle 1–1.5 cm., less than half as long as the rest of the rhachis. Calyx deeply divided, 0.5–0.9 times as long as the filaments, which are 3.5–4.4 mm. long. Style 2–3 mm. long, more or less abruptly bent through 90° near the middle, hardly thickened at the base. Pod spreading, straight, up to 16 (rarely 18) mm. long, ± 1.8 mm. wide, densely covered with erect multicellular hairs ± 1 or 1.2 mm. long, 6–10-seeded; endocarp spotted. Fig. 41/15, 16.
