NiCANDRA. 



This genus of Adanson^ on account of its augescent vesicular 

 calyx, has been placed near Physalisj but it exhibits much dissi- 

 milarity in its habit, in the blue colour and aestivation of its large 

 bell-shaped flowers, and in the structure of its fruit. There is 

 only one recorded species, well known to our gardens, the old 

 Atropa physaloides, Linn., which is manifestly related to Atropa 

 and Anisodus on account of the form and imbricate aestivation of 

 its corolla and the nature of its fruit ; it differs however from both 

 these genera in the very peculiar character of its calyx, in which 

 respect it approaches Juanulloa, but it does not correspond with 

 that genus either in its habit, the structure of its corolla, or the 

 form of its embryo. It therefore takes its position in the tribe 

 Atropete [huj, op. vol. i. p. 166), and I annex an emended 

 character in conformity with my own observations made upon 

 the living plant,
