 TRIB. Species about 80, chiefly European and Oriental. : v" 



A genus in many respects intermediate between Cheiranthus and Sisymbrium* 1 

 Indian species are very difiGcult of discrimination, and little confidence can be placed 

 their diagnoses. They stand here as described 12 years ago in the Linnean Jourcai 



since which time no materials of importance for their elucidation have been recelvea.
