may belong to D. subcapitata. Oliver does not mention any such 

 plant in his List fl. pi., and I have not seen the specimens in the Nat. 

 Hist. Mus., or at Kevv, but Hart's description decidedly poinls towards 

 it. Indeed, he calls the flowers pale yellow, but as he says below that 

 "the colours white and yellow are of no value in describing a species 

 in these latitudes", this is of no consequence. If my supposition is 

 right, the localities: North coast, Floeberg Beach and Grinnell Land, 

 Alexandra Lake and Discovery Harbour, have to be added. 



Distribution. This is very difficult to give, and I can only state 

 its occurrence in the Arctic American Archipelago, Arctic America, 

 Novaja Semija and Spitsbergen, as quite certain. I have, however, 

 seen specimens that probably belong to it, from East Greenland (not 

 the D. Martinsiana of Dusen, Gefasspfl. Ostgronl., p. 26, which, as speci- 

 mens in the Stockholm collection show, is a D. hirta, that may be 

 referred to var. altaica], Jan Mayen, Arctic Siberia, Sikkim. Further 

 it probably grows in the Altai and other Asiatic mountains, and I think 

 that it will also be found in more localities, when sought for and 

 distinguished.

This plant is easily enough distinguished from other species except 

 that there may be a rather strong resemblance between it and small 

 forms of D. hirta var. arctica. It is not improbable, that the D. muri-

cella of Hart, Bot. Br. Pol. Exp., p. 25, may be this species, but I have 

 not seen specimens, and Oliver, List fl. pi., does not mention it, nor 

 does Greely, Rep. It grew generally in the richer slopes, especially in 

 the rookeries. It began to flower about midsummer and very soon stood 

 with ripe pods.
