spreading, 1-2 dm. long: leaf-blades various, spatulate to linear, sometimes broadly so, 
sinuate-pinnatifid or the upper ones entire: involucres 6 mm. high at maturity; bracts 
oblong to lanceolate: ligules orange : achenes about 1 mm. long, prominently ribbed and

3. Serinea Wrightii (A. Gray) Kuntze. Foliage glabrous, or slightly glandular- 
pubescent along the peduncles under the heads. Stems more or less diffusely branched at

spatulate to linear-spatulate, 2-6 cm. long, usually acute, entire or undulate: peduncles 
slender, sometimes longer than the rest of the branches: involucres 5-6 mm. high at ma-

12. CICHORIUM L. 
Perennial herbs, with rigid branching stems. Leaves sometimes mainly basal : blades 
toothed or pinnatifid, often crisped. Heads showy, white, pink, blue or purple, peduncled 
or sessile and often clustered. Involucres herbaceous: bracts in 2 series, the outer more or 
less spreading, the innererect. Receptacle flat, naked or sparingly fimbrillate. Ligules nar- 
row, toothed and truncate at the apex. Anthers sagittate at the base. Stigmas slender, 
rather obtuse. Achenes short, 5-ribbed or 5-angled, beakless, more or less completely 
enclosed by the inner bracts of the involucre. Pappus of 2 or 3 rows of short scales. 
1. Cichorium Intybus L. Tap-root tough, elongated. Foliage hirsute or hispidu- 
lous at least below: stems erect, 3-15 dm. tall, rigidly branched : leaf-blades various ; basal 
spreading, usually runcinate, 1-2 dm. long ; those of the stem oblong to lanceolate, entire, 
coarsely toothed or pinnatifid : involucres about 1 cm. Jong; bracts lanceolate to linear- 
lanceolate, glandular-ciliate above : heads sky-blue or white, 2.5-4 cm. broad, closing by 
noon: achenes slightly enlarged upward, 2-2.5 mm. long, minutely wrinkled. 
In waste places, fields oron roadsides, Nova Scotia to Minnesota, Nebraska and Florida. Summer
