Lettuce Endive 361 



Kinney (10th Eept. E. I. Exp. Sta., 1897) classifies lettuce 

 chiefly on the shape, color and margin -characters of the leaves. 

 He describes 99 varieties. A condensation of his scheme is as 

 follows : 



A. Leaves entire near the apex. 



B. Leaves as long as or longer than broad, 

 c. Color red or blotched. 

 (Minor divisions.) 

 cc. Color green. 



(Minor divisions.) 

 BB. Leaves not as long as broad. 

 AA. Leaves dentate near apex. 



(Divisions much as in A.) 



American seedsmen offered 119 varieties of lettuce in 1889. 

 For history, see Sturtevant, Amer. Nat., Nov., 1888, pp. 984-7. 

 Field -grown lettuce has few enemies. 



ENDIVE * 



Endive affords a good supplement to lettuce, since it 

 Is essentially a summer and fall crop and thrives at a 

 season when lettuce is somewhat difficult to grow to per- 

 fection. The culture is not unlike that of lettuce, except 

 that the plant requires a longer time in which to mature. 

 Seeds sown in June may be expected to give plants 

 fit for the table by August and September. 



In respect to soil, tillage, distance apart and other 

 treatment, the care of endive differs little from that of 

 lettuce. The plants should stand about a foot apart 

 each way. The green, rank leaves are likely to be bitter
