Cardaria, Coronopus, and Stroganowia are united with Lepidium (Brassicaceae)

The genera Cardaria (including Himenophysa), Coronopus, and Stroganowia are hardly distinct morphologically from the larger Lepidium, and the distinctions of all four genera are based solely on a few fruit Characters of doubtful value. Recent molecular data strongly Suggest that the genera Coronopus and Stroganowia are polyphyletic and, together with Cardaria, are nested within Lepiditan. Therefore. they are herein fornially united with Lepidium, the earliest published generic name in this group. The new names L. appelianum L. botschantserianum, L. buschianum, L. karelinianum. and L. are proposed because the transfer of their replaced names to Lepidium would create later homonyms. The following 20 ne combinations are proposed: L. brachyotum, L. cardiophyllum, L. englerianum, L. lepidioides, L. litwinowii. L. longifolium, L. minor, L. navasii. L. paniculatum L. rhytidocarpum, L. robustum. L. sagittatum, L. sararschanicum, L. serratum, L. tianschanicum, L. tiehmii. L. tolmaczorii, L. trautvetteri, L. violaceum. and L. zambiensis.
