The name of Rudbeck is familiar to most bot- 
anists. A portion of a work by the elder professor 
of this name, in the Sherardian Library, at Oxford, 
should be inspected by every one who has an oppor- 
tunity of doing so. It is a specimen of the botani- 
cal zeal and industry that existed prior to the labours 
of the celebrated Linneus. 
This showy species, named by Professor Horne- 
mann, of Copenhagen, belongs to the genus Echin- 
acea, as established by the German botanist Moench. 
It was raised in the Birmingham Botanic Garden, 
from seeds communicated by Mr. Hunneman, who 
had received them from the Continent. We are 
not aware of its existence in any other collection in 
this country; it may, nevertheless, have been intro- 
duced to others from the same source. 
Rudbeckia asperrima, in the open borders, be- 
comes a very showy plant; and, like most others 
of the same genus, requires but little attention if 
planted in a light rich soil. The roots may be divi- 
ded in spring or autumn; but the former season 
should be preferred, that it may not have long to 
remain dormant after removal.
