According to the collections of Berlin and Knutsen in 

 1883 and 84 we knew from Angmagsalik 109 species, to which 

 Nathorst in a later work adds still 2 species, thus in all 111. 

 To these Hartz adds 5 on the basis of the collections of Bay, 

 so that 116 species Avere known from the district in 1892 (not 

 as stated by Hartz (I.e. p. 392) 120). Of these 116 species are 

 omitted Triglochin 'palustre^ as well as Draba corymbosa and 

 Campanula groenlandica, that are not or at any rate in this list 

 are not considered different as to species from severally Draba 

 hirta and Campanula rotundifoUa, after which the number of 

 known species is reduced to 113 species. In this list are 

 mentioned 183 species, so that the number has been added to 

 with 62 ^/o, though the conception of species has been taken 

 in a very wide sense. Thus I have with Gelert united Draba 

 rupestris and corymbosa with Draba hirta, Glyceria Borreri 

 with G. distans, Festuca duriuscula with F. ovina, Campanula 

 groenlandica with C. rotundifoUa, and Woodsia ilvensis, gla- 

 bella and hyperborea are considered to be one species, while 

 the Alchimilla forms filicaulis, alpestris, Wichurae and glome- 

 rulans are considered to be separate species. In spite of 

 that the augmentation is very considerable, and though the 

 number has not been increased to the double of it, as foretold 

 by Warming, still Nathorst was very far from being right 

 when he declared that, what might still be found would be only 

 single "plantae rarae" of no importance for the flora as a whole. 

 No less than 52 of the species added are plants of a wide 

 distribution which within Greenland itself have been found in 

 very different locahties and bear a prominent part in the phy- 

 siognomy of the vegetation ^), and even within the district given
