less, usually purplish : leaves an inch or two long, spatulate or oblong-ovate and 

 petiolate, mucronate : bracts linear-setaceous, rather conspicuous : involucres 2 or 3 

 lines long, or more, with very unequal teeth, the alternate ones often much enlarged 

 and widely spreading : flowers sessile, glabrous : perianth-segments exserted, obtuse 

 at the apex, coarsely fringed below. PI. Gambel. 168; Torrey, Pacif. R. Rep. 

 v. 364, t. 8 ; Torr. & Gray, 1. c.

14. C. laciniata, Torrey. Very similar to the last : involucres 1 J to 2 lines 

 long, the teeth less enlarged : segments of the perianth long-acuminate and copi- 

 ously fringed. Pacif. R. Rep. vii. 19; Torr. & Gray, 1. c. 



At San Felipe, Antisell. 



i -i Short segments of the perianth oblong, entire. 

 -H- Bracts not foliaceous. 



15. C. staticoid.es, Eenth. Erect or procumbent, rather stout, often a foot 

 high or more, with spreading branches, villous-pubescent, often purplish: leaves 

 all radical, tomentose beneath, oblong, obtuse, 1 to 2J inches long including the 

 petiole : bracts all acerose : involucres in rather close cymes, 1J to 3 lines long, 

 the alternate teeth larger and nearly equal, often much enlarged : flowers nearly 

 sessile, 2 to 2| lines long, glabrous, cleft a third of the way down : segments rather 

 narrowly oblong, entire, the alternate ones nearly half shorter and usually narrower : 

 stamens at base. Linn. Trans, xvii. 418 ; Torr. & Gray, 1. c. 



From Monterey to San Diego. 



16. C. procumbens, Nutt. Slender and procumbent, branching from the base 

 and very diffuse, villous-pubescent, and often yellowish : leaves spatulate, an inch 

 long or more, not tomentose : bracts mostly small : involucres 1 to 1 ^ lines long, 

 the alternate teeth strongly divergent and about equalling the tube, uucinate : 

 flowers yellowish, sessile, 1 lines long, glabrous or somewhat villous : segments 

 equal, narrowly oblong, obtuse and entire : stamens at the base. PL Gambel. 

 167; Torr. & Gray, 1. c. 



Collected only about San Diego. 



H- -H- Bracts more or less foliaceous. 



17. C. Parryi, Watson, 1. c. Small (2 or 3 inches high), branching from the 

 base, villous-pubescent, leafy : leaves narrowly oblanceolate, an inch long, not 

 tomentose : lower bracts as large, similar, pungent : tube of the involucres a line 

 long, the very divergent alternate teeth as long or longer : flowers nearly sessile, 

 white or pinkish, 1 J lines long, villous on the nerves, cleft nearly to the middle : 

 segments recurved and somewhat undulate, oblong-ovate, crenate, acutish ; the inner 

 ones narrower arid scarcely shorter : stamens at the base. 



Common on gravelly mesas near Crofton, San Bernardino County, Parry, 1876. 



18. C. Xanti, Watson. Small (2 to 4 inches high), branching diffusely from 

 near the base, villous-pubescent and tomentose : leaves ovate-oblong, 2 to 6 lines 

 long, on slender petioles, tomentose beneath : the lower bracts similar or linear- 

 oblanceolate : involucres tomentose, in diffuse cymes, the tube 2 lines long, with 

 very divergent teeth often half as long or more, the alternate ones much smaller : 

 flowers rose-colored, 2^ lines long, sessile, villous : segments linear-oblong, entire, 

 acutish, the alternate ones a half shorter : stamens 6 (rarely 7 or 8), at the base.
