Isatis iconia Boiss. & Heldr. in Boiss., Diagn. Pl. Orient. 8: 48. 1849.

 Isatis glauca subsp. iconia (Boiss. & Heldr.) P.H. Davis in Notes Roy. Bot. Gard. Edinburgh 26: 22. 1964.

Type: “Hab. in agris propè Koniah (Heldreich)”.

Holotypus: TURKEY: “in campis Koniah”, 16. VI .1845, Heldreich 827 (G-BOIS [G00332598]) .

Notes. – No duplicates of the type collection were seen in any of the major herbaria consulted, and it is not known if Heldreich collected more than the type specimen above.

The holotype is a collection folder of two sheets, of which the labeled, barcoded one consists of the lower part of the plant, and the other sheet is unlabeled and consists of an infructescence. Without either of the two sheets, it is impossible to know the identity of the species. It is also unknown if the two sheets belong to the same species.

No complete fruiting collections of the species were examined for this study, and a designation of such material as an epitype is highly desirable.
