generally spreading. Stamens 10. Nectariferous scales entire, or 

 hardly emarginate. Carpels 5. Herbs or subshrubs. Stems 

 usually branched from the base. Sterile stems or surculi usually 

 crowded with leaves. Leaves alternate, rarely opposite, fleshy, 

 terete or flat, quite entire, rarely toothed. Flowers cymose, white, 

 purple, or blue, but usually yellow ; in some species the flowers 

 are 4 or 6-7-petalled, and the stamens always double that number.

1 S. RHODIOLA (D. C. fl. fr. ed. 3. vol. 4. p. 886. pi. grass, 

 t. 143.) leaves oblong, serrated at the apex, glabrous, glaucous ; 

 root rather tuberous ; stems simple ; flowers corymbose, usually 

 of 4 petals, octandrous, and dioecious from abortion. 7^. H. 

 Native of middle Europe, on the mountains ; of Siberia, and of 

 North America, on the Arctic Sea shore, and Islands ; of New- 

 foundland and Labrador ; and on the Rocky Mountains, Kot- 

 zebue's Sound, &c. ; in Britain, in the north of England, Scot- 

 land, and Wales, on the mountains. Rhodiola rosea, Lin. spec. 

 1465. Smith, engl. bot. t. 508. fl. dan. t. 183. Plant glaucous. 

 The flowers are yellow, and are said to be sometimes hermaphro- 

 dite, but are usually of different sexes on different plants. The 

 root is sweetish when dried ; in this state a fragrant water may 

 be distilled from it. The inhabitants of the Farro Island use it as 

 a remedy for scurvy. In Greenland they eat it as garden stuff. 

 A cataplasm of the fresh roots, applied to the forehead, is said 

 to relieve the head-ache, and to heal malignant ulcers. The 

 specific name is from poSov, a rose ; in reference to the fragrance 

 of the roots.
