Much smaller than the last j the fruit globular, with a straight 

 beak ; the colour of the whole plant less yellow. There appear 

 to be some exotic varieties of C. flava that approach it, though 

 the British^ara always seems distinct enough from our Oederi. 

 Schkuhfs t. F. /. 2G, rather perhaps belongs to Jiava, but 

 Ehrhart's dried specimen accords with our's. 1 have not studied 

 the subject so as to decide confidently, nor perhaps has any 

 other English botanist.
