NICANDRA. 
This genus of Adanson, on account of its augescent vesicular 
calyx, has been placed near Physalis, but it exhibits much dissi- 
milarity in its habit, in the blue colour and estivation 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 estivation 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 
Atropee (Ann. Nat. Hist. 2nd Ser. i. 166), and I annex an 
emended character im conformity with my own observations 
made upon the living plant.
