H. G. SIMMONS. [SEC. ARCT. EXP. FRAM 



nell Land. Lnrtxiu <tli>ina is found in America only in Labrador, but 

 it is rather a common plant in Southern Greenland. It must doubtlrs- 

 have come to N. W. (Greenland from Ihe south, and is to be placed in 

 linmp S. Jji-hila nana is distributed in West Greenland from H3 

 northwards, mid, in the east coast, from the Angmagsalik district north- 

 wards to 73 1 o. To the south it is replaced by B. (jlaudulusa. but it 

 appears again in N. E. America, not, however, in the arctic parts. It 

 must also go to Group S, species spread in Danish Greenland, where 

 they are probably immigrants from Labrador and wandering northwards 

 from there. How it has reached Eastern Greenland is another question; 

 it may have come from Iceland, or its area may once have been conti- 

 nuous in the south. Glyceria tenella has so discontinuous a distri- 

 bution that it can only be placed in Group D. 



Taraxacum arctogenum, in Group II, 4, is an endemic Greenland 

 species (Gr. G). Montia lamprosperma belongs to Group S, it is spread 

 to the south in Danish Greenland but seems to be lacking in Arctic 

 America. It may have reached Greenland from the east, as it is com- 



J 



mon in Iceland and the Faeroes: or from Labrador, where it seems to 

 grow, if the indications of BRITTON & BROWN, 111, Fl., II, p. 4, about 

 ''Moiitia fontana' are to be trusted and thus interpreted. 



Group III, 1, contains 4 species of which one, Carex manhnuw- 

 pacta. is entirely american; two, Chrysosplenium alter )ii folium and 

 Alsine Eossii, are lacking in Greenland but reach from Asia as far 

 west as Spitsbergen or (the former) still further in the south. The fourth. 

 Draba subcapitata, is somewhat doubtful, but its distribution in Elles- 

 mereland and further to the south-west, shows that it is an american 

 -pecies within the western parts of our special area at least. It is not 

 yet known with certainty from Greenland, but has a circumpolar distri- 

 bution reaching, on the Atlantic side, to Jan Mayen. These 4 species 

 are to be placed in Group A. Here belong also the species of Group 

 III, 2, which have reached N. W. Greenland. Taraxacum Ityparcticum 

 and li'dHtutcnhis Sabinei are entirely american, Pedicularis capitata 

 and P. arrlini are spread from Eastern Siberia throughout Arctic Ame- 

 rica. Hespcri* I'allasii reaches as far west as Novaja Semlja. They 

 have doubtless come to Greenland over Smith Sound, as is also the 

 case with J'oti'Htilla Vahiiana from Group III, 3. Pcdicularis latinta 

 al-o seems to be an american immigrant in Western Greenland, where 

 it i> , minimi in the northern colonial districts. It is, however, a cir- 

 unipolar plant, and appears also in a small area in S. E. Greenland.
