1909. No. 8. VASCULAR PLANTS COLLECTED IN ARCTIC NORTH AMERICA. I3 
It appears from the history of the name »C. serpyllifoliume, that it 
cannot stand for our form, and I am therefore obliged to give a new 
name. I propose the name C. Regeli in honour of the botanist who has 
had the best idea of our species in its ordinary form. 
I have seen specimens in the Copenhagen herbarium from Spits- 
bergen (A. J. MALMGREN, E. JØRGENSEN, RESVOLL-DIESET, THORILD WULFF), 
Franz Joseph Archipelago (H. FisHer), both North- and South- 
islands of Novaya Zemlia (H. W. Fermpen, TH. Horm), Waigats and 
Dolgoi islands (H. W. Feen, F. R. Kyettman & A. N. LunpstrR6m), 
Yugor Schar (Tu. Horm), Mouths of the river Ob at Obdorsk (Hace) 
and of the river Yenissei (A. N. Lunpström) and the Arctic Sea coast 
at 85° 8 Long. E. (F. R. Kjerrman). If to these we add the distribution 
given by E. REGEL and its occurrence in King William Land, we get a 
circumpolar distribution with large gaps. It seems mainly at home in 
Eurasia, where the principal region ranges from Spitsbergen to the mouth 
of Yenissei river; the next region is East Siberian and Beringian, and 
lastly the strange record of its occurrence in the central part of Arctic 
America, viz. King William Land. In Greenland and Ellesmere Land it 
is absent (cfr. H. G. Simmons, Rep. Sec. Norv. Arct. Exp. in the Fram 
1898—1902, No. 2, 1906, pp. 120—123). ANDERSSON & HESSELMAN records 
our species — as C. Edmondstonii, var. cæspitosum — from Dovre in 
Norway according to specimens collected by J. E. & P. L. ZETTERSTEDT on 
July 24th 1854 and now in the Riksmuseum of Stockholm; we have also 
specimens in the Copenhagen herbarium from the same collectors and 
same date, but they belong to the true €. Edmondstonii, so that I still 
doubt if €. Regelii occurs in Scandinavia.

Numerous specimens in full flower were collected, many of them with 
empty capsules from the year before. They were taken as early as 
July 17th (1904) and as late as Aug. 6th (1904) still only in flower. 
The specimens vary very much with regard to the shape, segmentation 
and hairiness of the leaves.
