The bractlets are ovate, subobtuse at the top, of a dark brown, Vi to -A as long as 

 the flowers. The leaves are comparatively broad, 1 to 1,5 mm. The stems are solitary, 

 generally not tufted. 



Distribution: Arctic and alpine tracts of Europe, south-western and central Asia, 

 Siberia, northern Mongolia, North America, Greenland.

The specimens collected are characteristic in having the stems vigorous, to >!> m. 

 high, glabrous, moreover in having the leaves rather broad, 4 — 6 mm., completely 

 glabrous, even the orifices of the sheats being destitute of tufts of hairs. The flower 

 cluster is made up of numerous, small, globular, and few-flowered spikes, 10 to 15 in 

 number, on stiff, erect peduncles, to 5 cm. long. The lowest bract foliose, equalling or 

 even exceeding the inflorescence. The capsule is of the same length as the perianth. 



Occurring in the Altaian, near the tree limit, with ripe capsules at the end of July. 

 I have also observed the species near Ust Sisti-kem and at Ust Kamsara. 



Distribution: Temperate portions of Europe and Asia, North America, Australia.

Rather common in the Altaian, above the tree limit, in moist, mossy and grass- 

 grown places. 



Taken with nearly ripe fruits at the end of July. The material collected agrees 

 perfectly with Scandinavian specimens. 



Distribution: Arctic regions of the old and new world, in more southerly tracts 

 only on lofty mountains.
