A hardy herbaceous plant introduced from California by 

 the Horticultural Society, in whose garden it flowered in 

 June 1836. 



It is not a horticultural plant, being too weedy to offer 

 any reasonable probability of being improved by culture, 

 but it is interesting to Botanists as an evidence of the extent 

 to which species vary permanently in their wild state. That 

 it is a mere variety of PotentiUa glandulosa, figured at plate 

 1583 of this work, I cannot doubt, and yet the wild speci- 

 mens have the ])etals longer than the calyx, the stem weaker 

 and less glandular, and the leaflets not only deeply cut as 

 well as serrated but strikingly cuneate at the base, and 

 pointed at the other end, instead of having a roundish oblong- 

 figure. These distinctions, which are sufficiently obvious 

 when the plant is wild, become so much more striking in 

 cultivated individuals that a Botanist, unacquainted with the 

 wild plant, might be well excused for supposing it to be a 

 distinct species.
