 high or more, with sjireading branches, villous-pubescent, often purplish: leave.s 

 all radical, tonientose beneatli, oblong, obtuse, 1 to 2^ inches long including the 

 petiole: bracts all acerose : invohicres in rather close cymes, 1^ to 3 lines long, 

 the alternate teetli larger and nearly (Mpial, 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.

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

 the alternate teeth strongly divergent and about eiiualling the tube, uncinate^: 

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

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, j)ungent: tul)e of the involucres a line 

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

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

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

 ones narrower and scarcely shorter : stamens at the base.

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

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

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

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

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