attached to the receptacle, persistent, dry, capitate. Seed protruding. 
Specific Character. — Plant perennial, herbaceous, growing from eighteen inches to three feet high.

Corolla rusty-brown, approaching to orange. 
In almost every flower-bed or border throughout the more populous parts of 
this country may be seen some one or other of the very interesting species of Poten- 
tilla. There is a simple beauty and elegance in their habits and flowers which 
seems to ensure for them universal esteem and cultivation, and there can be little 
doubt that the cheap price for which they may be obtained, after having been 
known for three or four years, contributes greatly to facilitate this extensive 
distribution. 
Among the species that are most admired, P. alrosanguima has ranked most 
deservedly high, as being one of the most ornamental ; and it is from a hybridiza- 
tion that has been effected between that species, and the pretty, but less showy one, 
P. pedata^ that the plant, of which the accompanying drawing is a representation, 
has been obtained. It will be seen by those who are acquainted with the species 
above mentioned, that the one here figured partakes of the character of both those 
species, combining the graceful form and foliage of P. pedata with some of the rich 
colour of the flowers of P. atrosanguinea ; but the latter only is possessed to such 
a degree as to preserve a marked distinction, and to render it worthy of being 
elevated to the rank of a species.
