Specific Character. 
Coreopsis filifolia ; glaberrima, caule erecto striato, foliis 
oppositis pinnatifidis bipinnatifidisque foliolis lineari- 
filiformibus subcarnosis supra canaliculatis, radii co- 
rollis 8—9 obovatis luteis, disco purpureo-sanguineo. 
Of all the narrow and divided-leaved species of Corzopsis, 
this has unquestionably the narrowest foliage, and which, if 
examined carefully, exhibits the most fleshy texture, the 
under side semiterete, and presenting no appearance of a 
nerve or costa, which indeed is only indicated on the upper — 
side by the presence of a furrow. _ Its nearest ally is perhaps 
the C. tenuzfolia ; but there, besides the difference in foliage, 
the disk is described as being of the same colour as the ray, 
and the florets of the ray are much narrower. Its seeds 
were sent by Mr. Drummonp to this country from Texas, 
in the spring of 1835, and the plants flowered in the open 
air in August and September. The same species is distri- 
buted to the friends of Mr. Drummonp’s Expedition, marked 
“Texas, Lin 101,” 
Descr. Annual. Stem erect, but slender, branched, 
especially upwards, striated and glabrous, as is every part 
of the plant. Leaves opposite, pinnatifid or bipinuatifid, 
allies the
