In Corea, there is one more species called Arabis axillaris, Kom. 

 which is likely of a different genus. It is also questionable that 

 Sisymbrium Maximowiczii, Palib. is verily a species of the genus, 

 though we can not determine their true systematic position by the lack 

 of its ripen fruits. Those two species resemble with each other in 

 their appearance except the former's slightly flattened siliques with 

 short beak and the latter's cylindrical one with long beak. So far as 

 my imagination can go, both belong to an undescribed genus. 



Here I have enumerated Stenophragma Thaliana, because it has 

 often been classed under Arabis. As I have stated in the key, Steno- 

 phragma has an incumbent cotyledones and the seeds are more roundish 

 than those of Arabis.
