Ledebour admits two varieties of JR. hijperiorms, diifering in the straight or hoolccd 

 style ; and B. jiygmceus only differs from the latter in the want of stolones. lu Sik- 

 kim both tlie ereet and the stoloniferous states occur, and specimens from that pro- 

 vince are identical in every respect with those of northern Europe. The heads of 

 fruit of this species ai-e a good deal like those of U. radicans, but smaller.

This elegant species agrees so weU with the description of li. amosnus, Ledeb., 

 which is universally considered to be the Siberian form of H. affinis, R. Br., that it 

 is difficnlt to consider it different, especially as there are specimens referred by bota- 

 nists to that species, not only of Siberian origin, but also from arctic America, which 

 are undistinguishablc from the Indian plant described above. iJ. Dahuric-us, Turcz. 

 mss. (which is quoted by Ledebour as a synonym of his R. pedatifidus), is certainly 

 the same as the- Indian plant, if the specimen in the Ilookcrian Herbarium may be 

 relied upon as authentic ; and it differs from the usual Siberian slates of R. afftnis
