The generic names of plants are usually derived 
from the Greek language, the specific from the Latin ; 
here, however, the order is reversed. Potentilla 
being deduced from the Latin potentia, whilst 
Haematochrus is evidently from the Greek aima, 
blood ; and ochros, pale. 
This newly discovered species of Potentilla was 
introduced into Great Britain, in 1838, from the 
Berlin Botanic Garden. It is, probably, quite hardy, 
but we are not aware of its having been hitherto 
exposed to the proof. Kept in a cold frame, during 
winter, and planted out in the spring, it succeeds 
perfectly ; and may be increased by division, or by 
seeds, which are produced in abundance. It re- 
quires only the common garden soil when planted 
out, but when potted, it will succeed best with the 
addition of a little peat and sand. This fact should 
not be lost sight of by the careful cultivator, that 
plants, when kept in pots, are placed under circum- 
stances so different from those to which they are 
exposed in the open ground, that their soil should 
be adapted, as nearly as is possible, to meet their 
altered situation.
