Notes. – Label of the lectotype has “ Persia. Dr. Buhse. 1847” pre-printed prior to collecting the material in 1849. It carries the species name handwritten perhaps by Buhse, but the locality in Boissier’s handwriting.

The syntype from Yezd was not found in G-BOIS and is most likely housed at LE.

This varietal name was not mentioned in Flora Orientalis, though I. songarica was listed in the synonymy of I. minima Bunge. Furthermore, it was not mentioned under the treatment of the latter species in Flora Iranica (HEDGE, 1968: 87).
