A very handsome October-flowering annual, a native of 
sandy plains in Texas and New Mexico, where it blossoms 
from the beginning of summer until the winter's frost cuts 
it off. The genus to which it belongs inhabits both tempe- 
rate North America and extra-tropical South America, and 
consists of about eight species, of which two have been 
already figured in this Magazine—namely, the old G. bicolor, 
Lam. (Tab. 1602), and its variety Drummondii (Tabs. 3368 and 
3551); and the large yellow-flowered @. aristata (Tab. 2940). 
The present species was discovered by Berlandier in 1527, 
and collected subsequently by Lindheimer in 1844, and by 
Drummond in 1845. The specimen here figured was raised 
from seed by Mr. Thompson of Ipswich, and flowered in 
October, 1873.
