CRUCIFER.E. 53 



plant is quite easily distinguishable from the type of C. Idrsuta LINN., 

 it is advicable, in my opinion, to regard it as representing a variety of the 

 type, rather than to regard it as a form of it.

HAB. Shii'ko : Kemoganslia. 



A very pretty herb ; the only species l)elouging to this genus in For- 

 mosa. The flowers and fruits of the plant resemble those of Dmba. But, 

 on account of its being qiiite glabrous, it should be referred to the present 

 genus.
