1898-1902. No 16. j FLOW. PLANTS AND FERNS OF N.-W. GREENLAND. 69 



As appears from this diagnosis, the variety differs from the type in 

 the mode of growth, the taproot carrying a number of branches, with 

 dense rosules of leaves, and several flowering branches again springing 

 from each rosule, the number of inflorescences thus often amounting to 

 a dozen or more. The branches are much shorter than the erect stems 

 of the type, and lie postrate on the ground, radiating out on all sides. 

 The seeds are yellow or somewhat brownish, not dark brown as LANGE 

 describes those of the type. They are for the most part placed in two rows. 

 A few half-withered white flowers were still to be seen in some plants 

 when I collected the specimens, August 11, 1899; most of the plants had 

 the greater part of the pods already quite ripe. In 1898, when I visited 

 the same places a few days later, I saw only rosules of leaves, no flow- 

 ering or fruiting specimens were then found. 



Occurrence. S. Foulke Fjord : at Elah (1466) and in the rookeries. 



Distribution (of the main species): Northern Danish West 

 Greenland, Arctic America (shore of the Polar Sea).

I collected only a few individuals at Foulke Fjord, where the spe- 

 cies seems to be less common than in Ellesmereland. One of them repre- 

 sents the var. glacialis, (ADAMS) KJELLM., which is recorded by previous 

 authors for several localities, of which I do not, however, think it nes- 

 sessary to give any specification, as there may be a question as to 

 what the different authors have understood by the name. Specimens, 

 .belonging probably to var. gracilescens, SIMM., I have seen in NATHORST'S 

 collections from Ivsugigsok. 



Occurrence. S. Ivsugigsok (NATHORST); Wolstenholme Sound 

 (INGLEFIELD), Umanak and Agpa (BALLE); Inglefield Gulf: Burdin Bay 

 (INGLEFIELD), Fan Glacier, Cape Acland (WETHERILL), M'Gormick Bay 

 (MEEHAN), Glacier Valley near Cape Robertson (WETHERILL), Northumb- 

 erland Island (STEIN); Foulke Fjord: Port Foulke (HAYES), Etah (1504); 

 Bedevilled Reach (KANE); Rensselaer Harbour (KANE). N. Lafayette Bay 

 (KANE); Polaris Bay (HART).
