Specimens belonging to this variety I have collected in the Altaian, above the limit 

 of tree vegetation, at altitudes' about 1900 to 2000 m. above sea-level, on rocks and stony 

 debris, with mosses and lichens.

The stems are much ramified, low, 10 to 20 cm. long, creeping, only reaching up to 

 about 10 cm. above the ground. The year's shoots are short, generally only from 1 to 1,5 

 cm. long. The leaves are very narrow, from 1 to 2 mm. broad, and from 10 to 14 mm. 

 long, with the margin much revolute. The corymbs are rather few-flowered, generally 

 from 3 or 4 to 8 or 10-flowered. The pedicels are comparatively short, 0,5 to 1 cm. long, 

 hairy and glandular. The length of the petals is to about 6 mm. Taken in full flower at 

 the end of July. 



Distribution: Scandinavia, excepting the western parts, Germany, Austro-Hungary, 

 Russia, except the extreme south, throughout Siberia from the Ural to the Tshuktsher
