This belongs to a small section of Geum, separated from 
it by Willdenow as the genus Sieversia, the species of which 
differ from their congeners in the style, which elongates as 
the achene ripens, but does not become suddenly bent or 
twisted above the middle; as, however, all its other cha- 
racters are those of Gewm, which the species altogether 
resemble in habit, I have reduced Sieversia to a section of 
that genus. It includes about a dozen species, natives of 
mountainous districts in Europe, northern Asia, and N, 
America, where one, S. Rossii, is a native of high arctic 
regions. Two are figured in this work—G. triflorum (Tab. 
2858) and G. Peckii (Fab. 2863), both North American 
plants. Gewm elatum inhabits the whole length of the 
Himalaya. In its typical form, as figured here, it ranges 
from Kashmir to Kumaon, at elevations of 9000.to 12,000 
feet ; further eastwards, in Nipal and Sikkim, it is replaced 
by a subalpine form, var. humile, Royle (Geum adnatum, 
Wall.), a small plant, with usually a one-flowered scape, 
which inhabits elevations of 12,000 to 15,000 feet.
