The generic name, Centrocarpha, is deduced from 
the two Greek words, kentron, a sharp point; and 
karphe, chaff. It has reference to the sharp brist- 
ley points which terminate the chaff of the recep- 
tacle. Chrysomela, from chrtjsos, gold ; and me- 
las, dark ; in allusion to the golden yellow colour 
of the ray, and the dark colour of the column. 
This plant has been known in the gardens, as 
Rudbeckia Newmanii, and is usually admired for 
its conspicuous gaiety, and for the long continuance 
of its flowers in perfection. These gradually grow, 
and as gradually assume their true colours; the 
ray from green to yellow, the column from green, 
through brown to black. 
We have met with varieties of this plant, having 
somewhat broader leaves, less hairy, and with flower 
stems more slender. They grew near each other, 
or their difference may have passed unobserved. 
This species of catrocarpha is not only shewy, 
but is most easy of management. It increases freely 
at the root, and may be divided at any time from 
September to May ; or, indeed, in the summer, with 
a little extra caution.
