Nasturtium macrocarpum Boiss. & Heldr. in Boiss., Diagn. Pl. Orient. 8: 18. 1849.

 Barbarea macrocarpa (Boiss. & Heldr.) Al-Shehbaz & Jacquemoud in Candollea 55: 202. 2000.

Type: “Hab. in ericetis siccis ad radices Antilibani inter Hasbeya et Rascheya, legi [Boissier] Maio 1846”.

Holotypus: LEBANON: “In ericetis inter Hasbeya et Rascheya”, V–VII.1846, Boissier s.n. (G-BOIS [G00332095]; iso-: G [G00389132]) .

Notes. – The holotype is a collection folder of three sheets of which sheet 1 has the label above and a barcode, sheet 2 has neither, and sheet 3 has only a label with: “Antilibanus infrà Rascheya” indicated.

The G isotype has the locality as “infra Rascheya”, but it is not possible to determine beyond doubt whether it is from the very same locality as the holotype.

The species is known from limited collections, and it is morphologically more at home in Barbarea than in an other genus of the family (AL-SHEHBAZ & JACQUEMOUD, 2000).
