1898-1902. No. 16.] FLOW. PLANTS AND FERNS OF N.-W. GREENLAND. 99 



F. ovina enters the arctic regions, as it is also in N. W. Greenland. 

 The specimens from Ivsugiksok, which NATHORST, N. W. Gronl., p. 27, 

 names as var. violacea, cannot be referred to the real F. violacea, 

 GAUD., hut helong to var. brevifolia. 



Occurrence. S. Ivsugigsok (NATHORST); Wolstenholme Sound: 

 Agpa (Saunders Island) and Umanak (BALLE); Inglefield Gulf: North- 

 umberland Island (STEIN); Foulke Fjord (HART), at Etah (STEIN) and 

 Reindeer Point (230, 1485, 1486); Rensselaer Harbour and Mary Minturn 

 River (KANE). N. Polaris Bay (HART). 



Glyceria Vahliana, (LIEBM.) TH. FRIES. 



I cannot of course decide what plant it may be which DURAND, 

 Enum. PI. Smith S., p. 95, has designed as "Poa Vahliana, Bot. Dan.? 

 (too young)", but it may perhaps be the real G. Vahliana, which occurs 

 sporadically in different arctic lands. The locality is noted as ''Port 

 Foulke etc., July 15". 



Glyceria tenella, LANGE. 



G. tenella, LANGE, in KJELLMAN & LTJNDSTROM, Fan. Nov. Semi., 

 1882; GELERT, in OSTENFELD, Fl. Arct. ; G. Langeana, BERLIN, Karlv. 

 sv. exp. Gronl.; LANGE, Consp. Fl. Groenl. II; ROSENVINGE, 2 Till, et 

 Nye Bidr. 



Fig. KJELLMAN & LUNDSTROM, 1. c., T. 6; OSTENFELD, 1. c., fig. 95. 



The specific rank of this plant, which seems restricted to Greenland 

 and Novaja Semlja, is perhaps somewhat doubtful, as is also that of the 

 following. I think it best, however, for the present to follow GELERT, 

 1. c., in keeping them both distinct from G. distans. I had not yet sub- 

 jected my Glyceriae to a closer examination when I published my Pre- 

 liminary Report. G. tenella was found sparingly on clay plains together 

 with other grasses. 



Occurrence. S. Foulke Fjord at Etah (1478). 



Distribution: West Greenland (sporadic), East Greenland (speci- 

 mens of a Glyceria collected in Kjerulf Fjord, Aug. 11 and 13, 1899, 

 by A. G. NATHORST and P. DUSEN, which KRUUSE refers to the following 

 species, seem rather to belong to the present), Waigats and Novaja 

 Semlja. 



Glyceria angustata, (R. BR.) TH. FRIES. 

 G. angustata, SIMMONS, Fl. Ellesm.
