by a curve, the whole summit corymbose : heads 54 inch high, 

 turbinate ; bracts linear-oblong, very obtuse, pale-green, 

 roughened with short papillose gland-tipped and viscid hairs : 

 some of the outer achenes glabrous, others like the inner

Springdale, Utah, M. E. Jones, 17 May, 1894. Species 

 strongly marked in many ways, the foliage comparable to that 

 of Tanacetum crispum in cut, but many times smaller, and 

 white with wool. 



Chaenactis cheilanthoides. Suffrutescent, producing 

 densely leafy sterile branches 6 inches high, and flowering 

 ones of a foot or more, these also amply leafy below the 

 corymbose inflorescence ; leaves tripinnate, 3 or 4 inches long, 

 1 inch wide, the ultimate segments all minute and rounded, 

 the whole leaf open and fern-like after the manner of common 

 species of Cheilantkes, quite white with a dense wooly indu- 

 ment when young and growing, later glabrate and greenish : 

 corymb of 8 to 12 turbinate heads nearly ^ inch high, on 

 slender pedicels, these and the involucres thinly villous- 

 tomentulose and minutely pellucid-glandular, the bracts sub- 

 equal, lance-linear, obtuse ; flowers of twice the length of the 

 involucre, flesh-purple, glabrous ; achenes villous-hirsute and 

 pellucid-glandular .

Clematis altheifolia. Habit and inflorescence of C.
