Origin of depicted specimens: Russia, Siberia, Baikalsky Chrjebet, Mt. Shartlay, near spring of the Lena river, 1900 m, Sphagnum bog, permafrost, collected by Vladimir Moloshnikov, Victor Voronin and myself July 20, 1980. At this site the vegetation period lasts only for 6-8 weeks, the remaining time of the year the soil is thoroughly frozen.

While flowering, the plants already develop their winter buds. They reach their full size before the seeds are ripe. On the day of this photography, July 21, the leaves of the left specimen in 8057 were already decaying. In mid-summer the permafrost begins 35 cm below the Sphagnum surface.

Most plants are totally overgrown by Sphagnum and peat grasses.

The scale in 8054 is 1 unit = 1 mm. Note the similarity with the rosettes of P. ramosa
