rather cumbrous, this inconvenience is more than 
counterbalanced by the advantage that it is ex- 
planatory of its hybrid origin. The female parent 
ought, we think, to hold the first place in such com- 
pounded name. 
We raised it from seed of the Pontentilla atrosan- 
guinea, fertilized with pollen of Potentilla pedata, 
and we believe a more perfect mixture of two dis- 
tinct and dissimilar species is not known. The 
dark red of the one, and full yellow of the other, are 
well mingled, and produce a rich deep orange. The 
foliage also of it is intermediate between that of its 
two parents, as shown by the engraving. 
In the year 1830, we fertilized flowers of each of 
the Potentillas, the atrosanguinea, formosa, and 
pedata, with pollen of the other two, separately. In 
each instance their anthers were destroyed before 
they had burst, the pollen of one of the other species 
applied to the stigma, and the flower then secured 
from insects, by a covering of gauze. Out of up- 
wards of two hundred plants thus obtained from 
Potentilla formosa, not one was sufficiently altered 
to merit notice. Nearly all those from Potentilla 
atrosanguinea, were somewhat improved. From 
Potentilla pedata, we obtained very few seeds. It 
is not a free seeding species with its own farina, and 
far less so under a privation of it. The plants from 
it were remarkably luxuriant, and its blossoms large, 
but otherwise they showed but little variation. 
The novel colour of this new hybrid flower, ren- 
ders it very desirable. The plant is slender, like 
that of Potentilla pedata, and in culture may be 
expected to require no peculiar attention.
