A very pretty annual, forming dense golden cushions in its 
native country, from the excessively branched corymbose 
habit of the plants which grow close together, and the abun- 
dance of flowering heads that open at the same time. It 
was found by all the early travellers in New Mexico, that 
Colorado district, ete., as by James, Coulter, Gregg, as well 
as by the later travellers, as Fremont, Wright, Fendler, ete.; 
and it was introduced into cultivation by Mr. Thompson, of 
Ipswich, in 1865, who sent specimens in that year to Kew. 
The genus Pectidopsis, founded by the elder DeCandolle 
for this plant, on the form of the pappus, has rightly been 
sunk in Pectis by Asa Gray. The organism in question being 
not only very variable in the genus, but in the present species, 
in which it consists of sometimes five pointed scales, at others, 
of retrorsely serrulate bristles, at others of 1-2-awned scales. 
Descr. A glabrous annual, six to ten inches high. Stem 
simple at the base, then excessively dichotomously branched 
in acorymbose manner. Leaves opposite, all cauline, one to one 
_ anda half inches long, linear-subulate, apiculate; margin’s
