15. Celsia lanceolata Vent., Descr. Pl. Nouv.: tab. 27. 1801.

Lectotypus (designated here): [IRAQ]: Hort. Cels, Ventenat s.n. (G [G00341500]!; isolecto-: G-BOIS [G00330749]!).

= Verbascum assurense Bornm. & Hand. -Mazz.

Notes. – The name Celsia lanceolata has been validated in Descriptions in 1801 based on a Bruguière and Olivier collection from Iraq (between Mosul and Baghdad) and cultivated in Cels’s garden. The specimen in Ventenat’s herbarium from Cels’s garden is designated here as the lectotype with a duplicate in G-BOIS. Four specimens collected between Mosul and Baghdad by Bruguière and Olivier have been located in G-BOIS [G00330748, G00330750] and P [P03287379, P03287380]. They are here considered as elements of original material. Huber-Morath (1981: 25) in his revision of Verbascum L. for Flora Iranica did not cite any type for Celsia lanceolata .
