spot at the base. Disk black-purple ; but the styles and 
stigma being yellow and exserted, occasion the outer rim, 
when the florets are expanded, to appear yellow. The 
palee are linear, and equal the floret in length. Seeds 
small, compressed, black, curved, naked. ; 
This species has a near affinity to tenuifolia ; from which, 
however, it is readily distinguished by its slender distorted 
stems; its outer calyx being barely half the length of, in- 
stead of equal to, the inner; and above all by the dark 
crimson base of the petals. j 
Native. of the whole of the Arkansa territory, as far as 
the Red River, North America, where it was discovered 
by Professor Nurraui, during his travels in that country, 
and an account of it transmitted to Professor Barron. It 
is of late introduction, and generally treated as a tender 
annual. Flowers the greater part of the summer. Com- 
municated by Mr. Anperson from the Chelsea garden, in 
September 1823, at which time our drawing was taken. 
We also received fine specimens in July last, from the 
botanic garden at Bury St. Edmunds.
