40. Lithospermum decumbens Vent., Descr. Pl. Nouv.: tab. 37. 1801.

Ξ Arnebia decumbens (Vent.) Coss. & Kralik

Lectotypus (designated here): IRAQ: de Bagdad à Mossoul, Bruguière & Olivier s.n. (P [P03877945]!; isolecto-: G-DC [G00149288]!; probable isolecto-: G [G00341671]!).

Notes. – A single specimen has been found in Ventenat’s herbarium. The collection probably lost its original label and only the locality “Barbarie” is noted though not in Ventenat’s handwriting. Two Bruguière and Olivier collections with a clear reference to the type locality (Baghdad and Mosul in Iraq) have been located. We designate the sheet at P [P03877945] as the lectotype because it is more complete than the more fragmented collection in G-DC. We consider the collection in Ventenat’s herbarium at G as a probable isolectotype.
