D. glacialis, not so stout as in D. alpina. The flowers are 

 white, but in pressing they often get a yellowish appearence, 

 which has caused some confusion. 



To this species belong: 



D. lapponica VVahlenberg in D C. Syst. 2. Leaves both 

 ciliated and hairy on the surfaces with small downy hairs. This 

 is the D. Wahlenhergii Hartm. v. heterotricha Lindblom in Bo- 

 taniska Notiser 1839. D. hrachycarpa Zetterst. in Botan. Notis. 

 1854 also belongs to the most hairy forms of D. Fladnizensis. 



D. androsacea Wahlenberg in Fl. Lappon. has only ciliated 

 leaves. Its synonyms are D. ladea Adams and D. Wahlen- 

 hergii Hartm. v. Jionwtricha Lindblom 1. c. 



D. Wahlenhergii Hartman combines D. lapponica Whlbg 

 and D. androsacea Whlbg, 



D. Wahlenhergii Hartm. v. glahrata Lindbl, 1. c. is the 

 glabrous form. 



D. Tschuktschorum Trautv. in Fl. Terrae Tschuktschorum 

 (Acta Horti Petropolitani VI) is nothing but D. Fladnizensis 

 f. heterotricha. Trautvetter has placed the plant in the section 

 Chrysodraha but, judging from the original specimens collected 

 by Maydell in the Tschuktscher-land , this is not right, the 

 flowers only have the yellow appearence, the plant often 

 gets by pressing, 



D. altaica Bunge, D. rupestris v. altaica Ledeb. is 

 D. Fladnizensis with short densely hairy stems, D. Martin- 

 siana Th. Fr. is, as above mentioned, a synonym, 



D. Wahlenhergii f. tenuisiliqna Lge, Gonsp. Fl, Groenl, p,670 

 is a form with linear-lanceolate pods. 



Some other synonyms for D. Fladnizensis from the flora 

 of Central Europe are , according to my view , D. Johannis 

 Host, D. carinthiaca Hoppe and D. Hoppeana Rudolphi. 



In Arctic regions D. Fladnizensis is found on the Arctic 

 shores and islands of America, in West Greenland from 

 64°— 74°, in East Greenland from 70°— 75°, Spitzbergen, 

 Beeren island, Novaya Zemlya, Ghabarowa, on the Arctic
