List of V^ascular Plants. 13 



It is known, moreover from N. E. Greenland, from N. W. 

 Greenland 1 (Ivsugigsok, A. G. Nathorst), EUesmereland (Fram Harbour, 

 H. G. Simmons) and Kamtchatka (Trinius), while the var. arctica is 

 more widely distributed over the whole Arctic region. 



Loc. Germania Land: Danmarks Havn, rather common. 



Note. It grows in clayey and wet soil at the margins of tarns which 

 dry up during summer, develops late, and is not seen in flower before August. 



Phippsia R. Br. 



26. Phippsia algida (Soland.) R. Br., Chloris Melvill., 1823, 

 p. 27; Gelert, in Ostenfeld, Fl. Arct., I, 1902, p. 101. 



Kruuse, East Greenland, p. 200. 



Due d'Orleans, Cape St. Jacques (Ostenfeld, 1908, p. 9). 



Loc. Mallemukfjcldet; Lambert Land; Germania Land, rather com- 

 mon; St. Koldewey. 



Flow. June 27th 08. 



Note. Grows on flat sandy shores and around small tarns and bogs on 

 rock^'-flats. 



Arctagrostis Griseb. 



27. Arctagrostis latifolia (R. Br.) Griseb., in Ledeb., Fl. Ross., 

 IV, 1853, p. 434; Gelert, in Ostenfeld, Fl. Arct., I, 1902, p. 107. 



Kruuse, East Greenland, p. 200. 



Loc. Germania Land, common. 



Flow. July 21st 07. 



Note. It flowers rarely and has not been found with ripe seed; often 

 the uppermost part of the panicle begins to wither before the flowering has 

 begun. It grows in bogs and at margins of ponds. Leaves as much as 

 9 5 ram. broad. 



Trisetum Pers. 



28. Trisetum spicatum (L.) P. Richter, PI. Europ. I, 1890, p. 59; 

 T. subspicatum (L.) P. Beau v.; Gelert in Ostenfeld, Fl. Arct., 1, 1902, p. 110. 



Kruuse, East Greenland, p. 199. 



Loc. Germania Land, rather rare. 



Note. Prefers sheltered localities, as also pointed out by H.G.Sim- 

 mons with regard to individuals occurring in Ellesmere Land; snow-covered 

 during winter. 



Pleuropogon R. Br. 



29. Pleuropogon Sabinei R. Br., Chloris Melvill., 1823, p. 31, 

 tab. D; Gelert, in Oslenfeld, Fl. Arct., I, 1902, p. 116. 



^ To this variety I refer also a ver}' interesting Aira collected in West Greenland 

 on the Island of Disco (N. W. coast, Giesecke's valley, 1902, Nr. 307) by M. P. 

 PoRSiLD. It is much higher than the true var. pumila (culms 20 — 30 cm. high), 

 but lias the setaceous leaves in common with it, also the characters of the 

 spikelets agree with it. In habit it comes very near A. setacea Huds. (A. 

 discolor Tliuill.; A. uliginosa Weihe).
