The plant here in question, has heen variously treated hy different 

 authors, and I have first, after comparing a large material and a great 

 many statements in literature, arrived at the conclusion that a new 

 name must be given to it. Hooker has (Bot. App. Parry II) establish- 

 ed a Draba inicropetala, with a description which agrees rather well 

 with the present plant, except for the character: "foliis lato-lanceolatis"; 

 but then J. D. Hooker has since shown, that the specimens on which 

 it is established, must be referred to D. alpina (Outl. of Distrib., p. 316). 

 In fact, it has not white flowers as said in the description but yellow, 

 as I have had the opportunity of verifying in the Nat. Hist. Museum, 

 where the original specimen from Igloolik is kept. In Fl. Bor. Amer. 

 I, p. 52, however. Hooker has added a /^, founded on specimens brought 

 home by Richardson from the coast between Coppermine and Mackenzie 

 Rivers. These are in the Kew Herbarium and belong to the same 

 plant, as that which I collected in Ellesmereland. Hooker has, how- 

 ever, given no name to the plant which he wrongly put together with 

 his D. micropetala. Indeed, a "minor" stands after the /i, but is not 

 in italics as the names are marked. As there are in the Fl. Bor. Amer. 

 many varieties marked only with Greek letters but having no name, 

 there can be no doubt about the "minor" being only a short description, 

 the more so as it is said about the specimen in flower "which differs 

 only from Gapt. Parry's plant in its smaller size". As the main D. 

 micropetala, is a form of D. alpina, here no name for our plant is to 

 be found, moreover as Hooker has placed under it also forms of B. 

 fladnizensis, as I have seen in the Hookerian herbarium at Kew. 



Another country in which the same plant grows, is Spitsbergen, 

 and from there it was brought home by the Swedish expeditions after 

 the middle of last century. It seems to have been first found by 

 Malmgren, 1861, who in Spetsb. Fan. Fl. doubtfully refers it to D. 

 pauciflora R. Br., which seems, however, to be a small D. alpina. 

 During the expedition of 1868, it was again found in several places by 

 Th. M. Fries and others, and Fries now called it (in Till. Spetsb. Fan.
