PricbJy Poppy. 



Calyx of 2 or 3 concave herbaceous sepals, nearly valvate 

 in aestivation, prickly outside, horned at the apex, caducous. 

 Petals twice as many as the sepals, imbricated in two series 

 and more or less crumpled in aestivation, hypogynous, dilat- 

 ed obovate-cuneiform, deciduous. Stamens indefinite, hy- 

 pogynous : filaments filiform : anthers innate, oblong, the 

 cells opening longitudinally by a slightly extrorse line. 

 Ovary oblong, clothed with bristly prickles, strictly one- 

 celled, with 4 to 7 parietal placentas which do not project 

 into the cell : stigmas nearly sessile, as many as the placen- 

 tae and placed directly over them, distinct, oval, disciform, 

 radiant. Ovules numerous in several rows on each placen- 

 ta, ascending, anatropous; the raphe superior. 



Capsule oblong or ovoid, usually prickly, many-seeded, 

 4 - 7-valved at the apex, leaving a replum of as many fili- 

 form intervalvular placentas which remain united by the 

 stigmas. Seeds horizontal, obovate-spherical, with a salient 

 smooth and naked raphe ; the crustaceous testa deeply re- 

 ticulated-scrobiculate. Embryo cylindrical, in the axis of 

 fleshy albumen, and two thirds its length ! cotyledons as 

 long as the radicle.
