LACTtFCA (from the old Latin name Jac ; referringto 

 the milky juice). Co>np6sit(P. Lkttuce. A well-known 

 genus of hardy annual or perennial herbs, mostly native 

 of the northern hemisphere. More than 200 specific 

 names have been given to the genus, probably half of 

 which are synonyms with but only 8 or 9 known in cult., 

 and these are doubtless forms of but 2 or 3 species. 

 Plants 2^ or more feet high, with alternate, variously 

 shaped lvs. and siuall-panicled heads of yellow, white or 

 blue fls. Only 1 species is to be found in the American 

 trade, though wild plants of other species are often 

 gathered for medicinal purposes or used as a salad. All 

 of the species possess narcotic and sedative properties, 

 the sedative known as lactucarium or lettuce-opium, 

 being obtained principally from the European species, 

 Ij. virosa. Xjettuce has been known and used as a salad 

 from a very remote period. It is said to have served at 

 the tables of Persian kings 400 B.C. See Letluvc. 



satlva, Linn. Letth'ce. An annual plant, not known

 types.
