Types. In the lettuce of commerce three distinct types are 

 recognized ; namely, head, cutting, and Cos lettuces, as shown in 

 figures 99, 100, 101. Besides these there is a fourth type, called 

 asparagus lettuce, little known in this country but resembling the 

 Cos type (see figure 102). Both the asparagus and the Cos resemble 

 the wild lettuce of the fields more closely than do either the head 



FIG. 100. Cutting (or cut-leaved) lettuce, var. intybacea 



or the cutting type. They have long lanceolate leaves like the 

 scariola and resemble it further in having a more acrid flavor 

 than either of the others. These forms are regarded as botanical 

 varieties and are recognized under the following names : head 

 (or cabbage) lettuce, var. capitata ; cutting (or cut-leaved) lettuce, 

 var. intybacea ; Cos lettuce, or romaine, var. Romana ; asparagus 

 lettuce, var. angustana.
