C. Intybus, L. (Fig. 1, pl. 161.) Curicory. Stems stiff, branched, 
1 to 3 ft. high. Basal leaves incised, or lobed, 3 to 6 in. long; upper 
leaves lance-shaped. Flowers in clusters on very short stems or none, 
blue, rarely white. Roadsides and waste places. July-Oct. 
KRIGIA, Schreb. (Adopogon, Neck.) 
Herbs, nearly smooth, the stem bearing a single head or more than one 
head. Leaves mostly basal, in our species one or more stem leaves or
