iJuring a stay in London in tlie summer of 1904, 1 have 

 had opportunity , through the kindness of the Keepers and 

 other officials of the herbariumdepartments of the British 

 Museum and at Kew Gardens, to see specimens of a great 

 many arctic plants. The principal result of my studies will 

 appear later, but I have thought fit to give already now an 

 account of a few rare or dubious species from Danish Green- 

 land, of which 1 have seen specimens there, and to add some 

 remarks about other species I have had to examine in connec- 

 tion with my studies for the Ellesmere-Grinnelland Flora. 



In several instances my search has only given negative 

 results, there being no specimens in the herbariums under the 

 name used in the publications. Now in many cases the labels 

 especially of the plants from the Nares' Expedition of 1875 — 76, 

 contain only the locality and the name of the collector, not 

 the name of the plant, and it can therefore not be seen if the 

 specimen has been referred by the collector to another species 

 than that it is now put to, but as there are, as far as 1 can 

 judge, complete sets of the collections of Hart, Feilden, Taylor, 

 and others in the British Museum and at Kew, I think that 

 absence of specimens of several dubious plants proves almost 

 to certainity, that the specimens have at first been wrongly 

 determined. The absence of specimens of plants only reported 

 by some of the above mentioned collectors seems consequently 

 to prove that the species in question are to be excluded from 

 the flora of Greenland and I therefore mention some cases 

 where no specimens were found.
