Recently Rechinger f. and Dulfer (Sitz. Osterr. Akad. Wissen. Math.-nat. Kl., Abt. 1.177. Bd. 4. bis 7:89-132. 1969) have reduced Astragalus maculatus Bunge 1868 (non Lam 1783), Astragalus holdichianus Aitch. & Baker, Astragalus sykesiae Simpson, Astragalus submaculatus Boiss. and Astragalus superfluus Rech. f. & Koie to synonymy under Astragalus mercklinii Boiss. & Bushe. I think Astragalus sykesiae Simpson and Astragalus holdichianus Aitch. & Baker are distinct species and it is not possible to uphold the view of Rechinger f. and Dulfer in this connection.
