pubescent; secondly, with a stem 3 feet high; thirdly, 

 with the leaves occasionally subserrulate ; and, fourthly, as 

 having middle-sized flowers and entire petals. Now in 

 (E. pallida, the leaves and calyx are perfectly destitute of all 

 kind of pubescence, both in the cultivated and spontaneous 

 specimens, the stem* never exceeds a foot or foot and half 

 in height, the leaves are never subserrulate, although they 

 are often dentate or slightly pinnatifid, the 'flowers can 

 scarcely be described as middle-sized, and the petals are 

 the reverse of entire. 



From (E. pinnat'ifida of the same author, it is obviously 

 distmguished by the total absence of pubescence ; and the 

 same peculiarity divides it from (E. speciosa, to which it has 

 otherwise a strongly marked affinity, especially in the colour 

 and appearance of its flowers, in its general habit, and 

 creepmg roots,— a character far from common in the genus. 



From the beautiful (E. roseo-alba of Reichenbach, it is 

 distinguished by the length of the tube of the calyx. 



Flowers from June to September. It is increased 

 readily by its creeping, roots, and also by seeds, which 

 are produced in small quantities. It flourishes more in 

 peat than in a loamy soil.
