The Greek words kentron, karphe, signifying 
sharp pointed chaff, are combined to name the 
genus to which the present plant belongs. Allusion 
is hereby made to the chaffy scales which are 
found on the receptaculum of the flower. 
This fine plant was discovered by the well known 
American botanist, Nuttall, who transmitted it to 
the late Mr. Barclay of Bury Hill, under the name 
of Rudbeckia nudicaulis — a different plant. The 
plants now belonging to Centrocarpha were for- 
merly included in the genus Rudbeckia. This 
genus was divided by the late Professor Don, and 
Centrocarpha is made to comprise such species as 
have an elongated receptaculum, and entire leaves. 
This is a remarkably showy autumnal flowering 
plant, which has become scarce, perhaps on ac- 
count of its being destroyed in severe winters, when 
planted in moist situations; during summer, how- 
ever, such situation is congenial to its luxuriant 
growth. Its roots may be divided in the spring, 
for increase; and, for its due protection against 
injury in winter, choose a light soil, and dry part 
of the garden.
