mote teeth or serratures at the margin, acute, obscurely 
nerved, on both sides pubescent with branched _hairs. 
-Corymbs of several flowers, axillary, from the upper leaves, 
and terminal. The axillary flowers in the wild specimens 
are not unfrequently reduced to a single blossom, as re- 
a, in the Flora Danica. Peduncles pubescenti- 
irsute, as are the pedicels, which are shorter than the 
calyx. Calyx with scattered patent hairs. Petals spathu- 
late, bright yellow, notched at the extremity. Germen 
subcylindrical, with the style about one quarter its length. 
Stigma two-lobed. Pouch oblongo-lanceolate, the valves 
plane, pubescent. Seeds numerous. 
Hitherto this species has only been known upon the 
authority of Vanz and Horneman asa native of Greenland. 
We have now the satisfaction of numbering it among the 
plants of the continent of North America, and likewise too, 
as a denizen of our gardens: it having been found by Mr. 
-Drummonp upon the summits of the Rocky Mountains; 
whence have been derived the seeds from which our flow- 
ering specimens were produced in the Botanic Gardens, 
both of Edinburgh and Glasgow.
