Though at first sight resembling a Pyrethrum or Matri- 
caria, more than a Helianthoid composite (in which tribe 
the flowers are generally yellow), this is an undoubted 
member of that group. It is a very handsome profusely 
flowering annual, a native of British Columbia, where it 
was discovered by D. Douglas in 1826, and extends from 
thence to Southern California in the west, and eastwards to 
Idahos and the borders of Mexico. Our plants were raised 
from seed kindly sent by Mr. Thompson, of Ipswich, 
and flowered in the open border in July, 1885. A. Gray 
describes a variety with rose-purple rays as occurring in 
California. ; 
Descr. A hispidly hairy leafy annual, excessively 
branched from the base, the hairs simple or mixed with 
shorter ones that are tipped with black glands, especially 
on the peduncles and involucres; branches slender, pale, 
’ terminating in solitary peduncled heads. Leaves alternate, 
_ one to one and a half inches long, by one-sixth to a quarter
