Discussion

Species 2 (1 in the flora).

Orychophragmus is fairly similar to, and closely related to, Moricandia, and they can easily be misidentified. The former has petiolate, pinnately divided, broadly auriculate proximalmost leaves, non-cucullate median sepals, apiculate anthers, and non-connivent stigma lobes. By contrast, Moricandia has sessile, entire, non-auriculate proximalmost leaves, cucullate median sepals, non-apiculate anthers, and connivent stigma lobes.

Orychophragmus limprichtianus (Pax) Al-Shehbaz & G. Yang is cultivated as an ornamental, rarely escaping.
