List of Vascular Plants. 15 



Kruuse, East Greenland, p. "204. 



Due dOrleans, Cape Bismarck (Ostenfeld, 1908, p. 9). 



As usual, this species is rather variahle. The tufted form occurs 

 among others. 



Loc. Cape Saint-Jacques; Cape Marie Valdemar; Germania I^and: Dan- 

 marks Havn; St. Koldewey. 



34. Poa abbreviata R. Br., Chloris Melvill., 1823, p. 29; Gelerl 



in Ostenfeld, Fl. Arct., Î, 1902, p. 124. 



Kruuse, East Greenland, p. 202. 



Due dOrleans, Maroussia Isl. (Ostenfeld, 1908, p. 9). 



Rich material of this high-arctic species was brought home. 

 It is evidently a well-defined species, and it is hard to understand 

 how Kruuse (1. c.) can "look on it as a high-arctic form of P. laxa.'' 



Loc. H3'de Fjord in Peary Land; Mallemukfjeld; Lambert Land; 

 Cape Saint-Jacques; Ymers Nunatak; Germania Land: Danmarks Havn, 

 common everywhere; St. Koldewey. 



35. Poa glauca M. Vahl, Flora dan., 1790, fasc. 17, p. 3, lab. 964; 

 Gelert, in Ostenfeld, Fl. Arct., I, 1902, p. 124; P. caesia Sm., Fl. Brit., 

 I, 1800, p. 103. 



Kruuse, East Greenland, p. 203. 



Loc. Ymers Nunatak; Germania Land: Dove Bugt, Lille Snenæs, Dan- 

 marks Havn. 



Festuca L. 



36. Festuca ovina L., subsp. brevifolia (R. Br.) Hackel, Botan. 



Centralbl., 1881, p. 406: Gelert, in Ostenfeld, Fl. ArcL, I, p. 130, 1902. 



Kruuse, East Greenland, p. 204. 



Due dOrleans, Cape St. Jacques (Ostenfeld, 1908, p. 10). 



I think it is allowable to refer all the specimens to subsp. 



brevifolia (R. Br.) Hack., but I must admit that I have not been 



able to find any definite distinguishing character between this form 



and subsp. supina Schur, as it has been defined by Scandinavian 



authors. In one locality the species was viviparous (dunes at 



Dove Bugt). 



Loc. Germania Land, rattier common. 



Note. It prefers fairly sheltered places and is usually snow-covered 

 during winter. 



Salicaceae. 



Salix L. 



37. Salix arctica Pall., Fl. Ross. II, 1790, p. 86; A. N. Lundström, 

 Weiden Nowaja Semljas, Upsala, 1877, p. 31, fig. 1; S. groenlandica
