24. Grlyii, Hook. f. A small spreading shrub 1J4-3 

 ft. or more high: branchlets, under surface of Ivs., and 

 petioles densely covered with a soft white tomentum: 

 Ivs. oblong or oblong-ovate, l%-3}4 in. long, obtuse,

 candidissimus, Hort., has very white foliage. Var. 

 aftreo-marginatus, Hort., has Ivs. bordered with orange- 

 yellow. S. Cineraria is an old-fashioned garden plant, 

 sometimes known as "dusty miller," and at the present

 Lychnis Coronaria, and still another one is Artemisia 

 Stelleriana.

 white-floccose tomentose throughout to essentially 

 glabrous: sts. 1-3 ft. high, distinctly woody below, leafy: 

 Ivs. undivided and linear or narrowly linear-lanceolate 

 to pinnatifid with few to several linear-attenuate divi- 

 sions: infl. a terminal open corymbose cyme; heads 

 about J^in. high, radiate; involucre campanulate, com- 

 posed usually of 21 bracts subtended by numerous 

 attenuated bracteoles; ray-fls. commonly 13, rays yel- 



low; disk-fls. 50-70: achenes pubescent. S. Utah to

 bose cyme; ray-fls. 10-12, rays %-l in. long, white; disk- 

 fls. yellow. New Zeal. B.M. 8524. The white rays and 

 yellow disk-fls., and the profuseness of bloom, render 

 this species a very unusual member of its genus; it 

 should prove an interesting plant in horticulture.

3609. The florist's cineraria, a very large show specimen. Sup- 

 posed to have been developed from Senecio cruentus. 



(whence the above description, and from which the plant 

 would seem to be a Cacalia). Said to be a very orna- 

 mental plant resembling the following species. 



31. Petasitis, DC. (Cineraria Petasitis, Sims). VEL- 

 VET GROUNDSEL. CALIFORNIA GERANIUM. A robust 

 perennial 3-8 ft. high, somewhat hirsute-velutinous on
