than the blossom. Anther a oblong, compressed, obtuse, 

 erect, twin. 

 Pistillum. Germ en cylindrical, as long as the stamina. 



Style none. Stigma a knob, bifid. 

 Pericarpium. Silique cylindrical, generally with 2 valves. 

 Seeds many, egg-shaped, shining, adhering to the little 5falk 

 that connects them with the receptaculum. Receptaculum 

 narrow, situated between the seams of the valves, and ap- 

 plied close to the seams through their whole length, con- 

 tinuing entire. 



N. B. The Ch. majus produces a long pod of 1 cell ; the 

 Ch. glaucium and Ch. corniadatum a If ng pod of -2 capsular?, 

 and the Ch. hybridum a long pod with 3 valves. Ch. 

 majus has a capsula resembling a pod, with knots where 

 the seeds are placed ; it has 1 cell and 2 valves. The seeds 

 are egg-shaped, with a kind of crest along the back, and 

 fixed by each end to a thread-shaped receptaculum and be- 

 tween the edges of the valves. The Ch. glaucium and hybridum 

 have a very long pod-like capsula compressed transversely, 

 of 2 cells, 2 valves, and a partition inserted between the 

 edges of the valves. The seeds are globular, and fixed in hoi- 

 low cavities to the middle of the spongy receptaculum. This 

 Genus is distinct from Papaver by its siliquose peiicarpium.

 the others. 



Corolla. Petals 5, circular, flat, expanding, very large. 



Stamina. Filaments, numerous, hair-like, shorter than the
