20. CONRXXrCIA, Beiclib.

 TKIB. Species about 80, chiefly European and Oriental. 



A genus in many respects intermediate between Cheirarttkus and Sisymbrium. The 

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

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

 aince which time no materials of importance for their elucidation have been received.
