Notes.

This species is distributed throughout Kazakhstan, Uzbekistan, Tajikistan, Kyrgyzstan, and northwestern China (Xinjiang) (Podlech and Zarre 2013). We found this species (voucher number: MT 6-1) in the rocky and rubbly slopes of the Chu-Ily Mountain range, occurring at elevations of 850– 900 m. The morphological characters of this species are very similar to that of A. bossuensis Popov but distinguished by having stipules 2.5–3.5 mm long, white hairy, sometimes with black hairs (vs. 3–5 mm long, covered with white and black hairs), leaves 3–7 cm long; petiole 1–2.5 cm long (vs. 4–12 cm long; petiole 1.5–4 cm long), petals pink, often yellowish-tinged (vs. greenish-yellow) and pods 25–40 mm long (vs. 12–20 mm long).
