The leaflets are generally completely sessile, the terminal leaflet also included; the 

 petals are mostly rather small and short, in part quite orbicular. The stem is finely pubes- 

 cent, zigzaggy, stiff and ligneous, of a reddish or yellowish colour, the petioles spreading, 

 and with comparatively small stipules. During the flowering the sepals are ascending, 

 appressed to the corolla, while, in Scandinavian specimens, they are recurved. (Comp. 

 the records in Blvtt, Norges Flora III (1876) p. 1174; Hartman, Handbok i Skand. 

 Fl. (1879) p. 204; Neuman, Sveriges Fl. (1901) p. 397). On collecting this plant in the 

 Sayansk district, I found the above character to be rather noticeable. It appears that also 

 TuRCZANiNow, 1. c. has noticed the very same point. „Flores rosei, rarius albi. Calyces 

 tempore florendi erecti, dein deflexi." In specimens of var. grandiflorus Ledeb. from 

 Sakhalin, I have previously (H. PRiNTZ,Some Vascular Plants from Sakhalin, 1917), obser- 

 ved that the calyx during the flowering was not recurved either, but appressed to the 

 corolla. This character thus seemed to be a strongly marked and pervading trait in the 

 species in its eastern area. All of the specimens collected by me in the Sayansk tracts, 

 however, belong to the typical form. 



Occurring rather abundantly in humid, grass- and moss-grown places in the subal- 

 pine wooded tracts about the Upper Amyl, where taken by me in flower and with ripe 

 fruits in the middle of July. The plant is also dispersed over the Urjankai country, where 

 I have collected it at Ust Algiac and on the Upper Sisti-kem. 



Distribution: Northern Europe, Siberia, northern Mongolia, Manchooria, Sakhalin 

 (var. p. p.). North America (var. p. p.).

Pretty common in meadows and in thickets on the islets in the river Abakan, and 

 in brush-wood on the banks, where I have collected it with young flowers in June. Also 

 rather frequent in the Urjankai country, where taken by me near Ust Algiac, between Ust 

 Sisti-kem and the Kamsara, near the Tara-kem, and on the Dora Steppe, at Utinski as 

 well as in several places along the Bei-kem, where the fruits ripen at the end of July and 

 in August. In the Altaian it ascends to above the tree limit. 



Distribution: Europe, in the southern parts only on the mountains, Siberia, north- 

 wards to the Arctic Circle, northern Mongolia, central Asia, Manchooria, North America, 

 Greenland.
