In this genus, the general appearance of the fruit, when 

 come to maturity and separating, is, at first sight, more like 

 that of an Umbelliferous than a Cruciform plant. Each valve 

 is so contracted at its edges, as to form in itself a distinct 

 cell or capsule : the only opening is that minute one, by 

 means of which the seed is connected with the placenta. 

 It falls away, therefore, with the cell or valve, which is 

 indehiscent.
