from Greenland by Boissier, I. c, p. 678, notwithstanding I doubt 

 whether Wallroth's plant is the same. Indeed I have not seen the 

 original of Wallroth (Beitrage, p. 185 — 86), but the description seems 

 to show that, even if a St. maritima is probably meant, it cannnot be 

 var. sibirica. Specimens from Labrador lying in the Nat. Hist. Mus. 

 herbarium under the name "A. Idbradorica" had the outer bracts of 

 the involucre rather narrow and pointed, without membranaceous margin, 

 which accords with the description. Their most noteworthy character is 

 not mentioned in the description, viz., that the calyx is so minutely 

 and scarcely perceptibly pubescent as to be nearly glabrous on the 

 ribs as well as between them. A. arctica, Wallr., which is also found 

 in Arctic America belongs to the Pleurotrichae. 



The Ellesmereland specimens are very low, densely tufted, because 

 of the multicipital rootstock, but have rather big heads. In its only 

 station within the area, it grew in rather wet, occasionally flooded, 

 places, along small rinlets in company with Carices, Eriophorum 

 polystacMum, etc. When found, August 26th, 1899, it had almost 

 ceased to flower. 



Occurrence. South coast: in the great western valley in Fram 

 Fjord (1625). 



Distribution (of the variety): Northeastern Greenland, West 

 Greenland, Arctic American Archipelago, Arctic America, Northern 

 Siberia, Baikal (alpine ?), Finmark, Faeroes, Iceland. The principal form 

 is distributed along the coasts of the temperate parts at least of Europe 

 and America.

For my own part, I have not found this plant, and I was rather 

 inclined to think that sooner A. Chamaejasme, Host, could have reached 

 Grinnell Land, as I knew it to have been found in the south western 

 islands, but specimens seen in the Nat. Hist. Museum and at Kew 

 showed that Hart's determination was right. It can hardly be sup- 

 posed but that A. septentrionalis must also exist to the southwest, 

 even if as yet it is only found on the arctic coast of the continent.
