but a very short leafy green form received as Stephani from Bremen 

 appears to belong here ; also glaucous narrow-leaved forms from 

 Brussels, &c. 



/?. elongatum Ledebour, " Flor. Rossica," 2, 178 [pro specie). 



Height, 7-12 inches. Green or greenish. Leaves more or less elliptic or 

 oblong, acute or acuminate. Inflorescence dense, with bracts on the main 

 branches. Flowers yellow, shorter than the pedicels. Scales thrice as long as 

 broad. 



The only growing plant which I can place here with any confidence 

 came from Kegel and Kesselring as Rhodiola ovata (fig. 5, b). It is 

 a pretty slender male plant, pale green, inflorescence slightly bracteate, 

 flowers shorter than the pedicels, sepals and petals red on back, 

 yellow on face, stamens i\ times the petals, anthers buff, scales orange, 

 thrice as long as broad, carpels green, one-third the stamens. 



y. atropurpureum Turczaninow in Bull. Soc. Mosc, 13, 70 

 {pro specie). 



Height, 3-7 inches. Glaucous, rarely greenish. Leaves elliptic, spathulate, 

 or oblong-lanceolate, acute. Flowers purple, equalling the pedicels. Stamens 

 slightly exserted. Scales quadrate or oblong. 



Maximowicz describes the flowers as usually dark purple. The 

 only dark purple flowers I have seen are on a female plant in the rock- 

 garden at Kew ; it has glaucous oblong-oblanceolate leaves, and 

 appears fairly typical of the variety. Two pecuUar plants with less 

 highly pigmented flowers appear to belong here also : a female, 

 stems 6 inches, leaves dark, rather glaucous green, pectinately toothed, 

 scales short, bright red, carpels purphsh (fig, 6, a, b) — this came 

 from Mr. Bowles' garden ; and a very dwarf male plant, leaves green, 

 flowers brick -red, grown at Edinburgh under the name Rhodiola 

 lanceolata (fig. 5, c). 



8. Tachiroi Franchet and Savatier, " Enum. Plant. Jap.," 2, 366. 



Height, 3-7 inches. Glaucous. Rhisome cylindrical, elongate. Leaves imbricate, 

 later lax, the lower eUiptic subentire, the rest oblong- or linear-spathulate. 

 Inflorescence dense, leafy. Flowers yellow, longer than the thick pedicels. 

 Stamens slightly exserted. Scales oblong, emargitiate. 



This is the Japanese form of S. roseum. Avery distinct male plant, 

 received as Tachiroi from Bremen and from Kegel and Kesselring, 

 though quite green, agrees well with Japanese specimens of Tachiroi 

 at Kew and the British Museum. These growing plants have the 

 rhizome quite slender, cyUndrical, smooth ; stems many, 3-4 inches ; 

 leaves shining, green, small and obovate below, larger and oblanceolate 

 above, where they form an involucre ; inflorescence small, compact ; 

 flowers yellow ; anthers pale red ; scales oblong, orange ; carpels 

 small, less than half the stamens (fig. 6, c).
