 (Fhodiola rosea, Eng. Bot. t. 508. Roseroot. Mid summer -men.) 



Stock short, thick, and almost woody ; 

 the annual stems erect, stout, simple, 6 

 inches to nearly a foot high, leafy to the 

 top. Leaves alternate, sessile, obovate 

 or oblong, slightly toothed, from 6 lines 

 to an inch long, the lower ones often 

 reduced to brown scales. Flowers dioe- 

 cious, yellow or rarely purplish, forming 

 rather dense cymes, surrounded by the 

 upper leaves, which often assume a yel- 

 low or purple tinge; the males with 8 

 stamens, rather longer than the petals 

 and sepals ; the females with 4 carpels, 

 ending in short, spreading styles. 



In clefts of rocks, in northern and 

 Arctic Europe and Asia, and in the 

 higher mountain-ranges of central Eu- 

 rope and Asia. Abundant in Scotland 

 and in the higher mountains of northern 

 England and Ireland, descending also to maritime cliffs in western 

 Scotland. Fl. summer. The smell of the rootstock, when drying, 

 has been compared to that of roses, whence its specific name.
