subspec. scapigera Kegel, 1. c. 



All of the specimens collected, the stems of which vary from 3 to 6 cm. in length, 

 belong to the large-flowered form, entered by Hooker, F1. Bor. Am. I, as var. grandi- 

 flora. The length of the petals varies from 10 to 12 mm., being thus one and a half to 

 twice as long as the calyx. Of rather common occurrence in the Altaian, at an altitude 

 of about 1900 m. above sea-level, in somewhat moist places, among moss and the like. In 

 full flower at the end of July. 



Distribution: Novaya Zemlya, arctic Siberia, the eastern Altai, the Sayansk district, 

 Baikal, Trans Baikal, arctic America.

The specimens belonging to this species, collected by me in the Altaian, are distin- 

 guished by having the stems rather coarse, rigid and erect, frequently slightly yellowish 

 and ligneous below. The petals are to li^ times as long as the calyx. Generally 2 — 3, 

 rarely to 5-flowered. Partly done flowering and with ripe capsules at the end of July. 

 The specimens seemed to agree perfectly with a rigidula Fenzl, 1. c. 



Distribution: Arctic islands, arctic and alpine tracts of Europe, arctic Siberia from 

 the Ural to Kamtchatka, the Altai- and Sayansk mountains, Baikal, North America.

On dry hills at Kushabar, where, besides the typical form with 4 sepals and 4 

 petals, there also occur specimens with 5 sepals and petals, var. peniamera Giirke (in 

 RiCHTER-GuRKE, PI. Eur. II, p. 246), whereas forms are to be found containing or wanting 

 distinct petals, a corollina et /J apetala (in Ledeb. Fl. Ross. 1. c). 



Flowering and with ripe fruits in the middle of July. 



Distribution: Europe, the Caucasus, Tibet, temperate Asia to about Lake Baikal, 

 North Africa, America, Greenland, Australia.

Scattered in the tracts between Minusinsk and Kushabar as weeds in corn-fields, 

 along road-sides, etc. Specimens taken in the fist half of July are in full flower.
