About 180 speeies in the temperate and warmer zones. 



The family, as aeeepted here, consists of 2 subfamilies, 

 viz. Papaveroideae and Fumarioideae. Stems and 

 leaves of Pa paver and Argemo7ie possess much-branched 



laticiferous tubes filled with a white or, as in the latter ease, 

 yellowish latex. In some species this contains narcotic sub- 

 stances, e.g. P. soimiiferum^ the common poppy, from certain 

 varieties of which opium is obtained (Asia Minor, India).
