the lowermost and radical leaves pinnatifid, with a greater 
or less number of segments, and indeed quite similar to that 
of G. bicolor and G. aristata of authors. The flowers in- 
deed appear different from both of those; but this difference 
is more dependent on colour, than any thing, and an atten- 
tive examination of numerous specimens of all three, both 
cultivated and wild, have led me to the conclusion that they 
are in reality varieties of one and the same species, which 
has thus a most extensive range, from the Gulf of Mexico, 
in lat. 24° to the Saskatchewan in lat. 52°, and from the 
Atlantic Ocean to the Columbia. Our Texas plant has a 
shorter ray than the other varieties, but is chiefly distin- 
guished by the deep sanguineous colour of almost the 
whole of the ray of the flower, so that the tips alone are 
yellow. The florets of the disk are more inclined to pur- 
ple, especially at the extremity. 
The specimen, from which our drawing was made, pre- 
sented another remarkable feature, in the florets of the ray 
having, every one of them, a bilabiate corolla, the outer 
with three large teeth and five branching nerves, the inner 
much smaller, lanceolate, with three such nerves. Other 
specimens from the same root had the ray only partially of 
this character.
