This species is, like the preceding one, rather varying, approaching it systemati- 

 cally rather closely, and is by some authors, Leuebour, Kegel and others, considered as 

 a variety, or even confounded with it. In 

 my opinion, however, these two species are 

 so different, not only in external habitus and 

 several other less conspicuous characters, a,« 

 it will appear from the descriptions, but they 

 are also distinct in point of geographical 

 range. The former is chiefly confined to arc- 

 tic and alpine tracts, and the latter — at 

 any rate to judge from my own experience 

 — rather a plant of the lowlands and the 

 steppes. I have therefore found it right to 

 enter them as two different species, applying 

 to the latter of these Stephan's name, in 

 spite of his having given no description of it 

 himself. 



The specimens collected are 15—40 

 cm. high, glabrous. The leaves are very 

 narrow, linear or nearly filiform, glabrous, 

 distinctly pointed at the summit. The flowers 

 are smaller, frequently rather numerous, 

 erect. The calyx 10 — 12 mm. long, narrower, 

 less inflated, with prominent nerves, and 

 longer and more acute teeth, which are 

 distinctly ciliate. The petals rather short, 

 only sligthly longer than the calyx; the claws 

 are glabrous. 



Collected in gravelly, dry places in the 

 lowland on the river Abakan, near Ust 

 Kamuishto. In full flower in the second half 

 of June. 



Distribution: The Altai- and Sayansk 

 region, eastwards through Trans Baikal to 

 the Amoor Province and Manchooria, Mon- 

 golia.
