NOTE

When describing this species, Gontscharov (1936) indicated that type specimens were collected from “Montes Transoxanae. Tut-Kaul ad fl. Vachsch., 8 May 1906, (446) (Leg. G. G. Morren)”, but Gorschkova (1954) thought that this species was “Described from Tut-Kaul, at the river Vakhsh” and mentioned that types specimens were deposited in LE ”. In this study, we have found four type specimens of D. baldshuanicum from LE. Having studied all the materials available to us in more detail, we concluded that the lectotype is stored in LE. Therefore, the lectotypification of D. baldshuanicum is proposed in conformance with Art. 9.3 of International Code of Nomenclature for algae, fungi, and plants ( Turland et al. 2018).

TAXONOMIC NOTES

Dracocephalum baldshuanicum is morphologically similar to D. royleanum Benth. , but can be readily distinguished by the corolla tube protruding from the calyx and its larger limb.
