In diy, grass-grown places in thicket of Salix, on an islet in the Yenisei, near Ust 

 Abakansk. Some specimens of this one, as yet flowerless, have been collected by me at 

 the beginning of June. It can, however, even in this phase of development, be distinguis- 

 hed from the following species, very nearly allied to it, and which, for the rest, it re- 

 sembles much in external habitus. 



Distribution: From the Altai region through southern Siberia to the western por- 

 tions of the Amoor Province, Mongolia, northern Tibet.

Only a few specimens have been collected by me in dry, grass-grown meadows on 

 islets in the river Abakan, near Ust Kamuishto. The specimens have stems 50 to 60 cm. 

 high, with very scattered, short hairs, the leaves now and then nearly glabrous, but rather 

 much glandulous. The leaflets are rather large, opposite, broad and ovate, 2 to 3 cm. long, 

 2 to 2,5 cm. broad, coarsely and irregularly indented at the margin, which is plane, not 

 revolute. The petals, which are of a pale yellow — to judge from dried material — are 

 somewhat shorter than the equally large and glutinous sepals, subacute at the summit. 

 The whole plant is, for the rest, more or less glutinous. Collected flowering in the second 

 half of June. I have also observed the species near Ust Sisti-kem, Ust Tara-kem, and at 

 Bjelosarsk. 



Distribution: Through Siberia, from the Ural to Manchooria, northern Corea, Mon- 

 golia, northern Tibet.
