Oxytropis azizii (Fabaceae-Faboideae) as a new combination supported by molecular and morphological evidence.

Based on molecular and morphological evidence, our results clearly indicate that Astragalus azizii should be reclassified as a member of the genus Oxytropis, representing a distinct species closely related to O. lapponica. In our molecular examination of the Astragalus sect. Brachylobium, we analyzed both the isotype and holotype of A. azizii and found that they were positioned among Oxytropis species in the nrDNA ITS-inferred phylogram. Through a detailed dissection of the flower, we observed the mucronate appendage on the keel petal — a diagnostic trait of the genus Oxytropis.
