Cochlearia L., Sp. Pl.: 647. 1753.

Tribe: Cochlearieae Buchenau.

Notes. – Cochlearia is a well-defined genus of about 16 species distributed primarily on costal northern North America, central, western, and northern Europe, and eastern Asia (KOCH, 2012).

The genus was so broadly delimited by Boissier in Flora Orientalis to include species currently assigned to Armoracia G. Gaertn.et al.(Cardamineae), Kernera Medik. (Kernereae), Peltariopsis (Boiss.) N. Busch and Pseudocamelina (Boiss.) N. Bush (Thlaspideae), and Noccaea Moench (Coluteocarpeae), but none in Cochlearia .

The first three taxa below were assigned to Pseudosempervivum for almost 50 years, and they have recently been transferred to Noccaea (ÖZÜDOĞRU et al., 2019) .
