1898-1902. No. 16.] FLOW. PLANTS AND FERNS OF N.-W. GREENLAND. 101 



withered when the specimens were collected, Aug. 11, 1899, were small 

 and contracted, with few spikelets on short branches. The number of 

 flowers in each spikelet does not exceed two, sometimes only one flower 

 is developed. Here consequently we find the typical features of "G. 

 vilfoidea', but the vegetative parts call to mind rather the description 

 of the var. arenaria, FRIES (Mantissa, 2, p. 9). The specimens of NAT- 

 HORST, which I saw in the Stockholm herbarium, represent the common 

 arctic form of var. reptans. 



Occurrence. S. Ivsugigsok (NATHORST); Foulke Fjord, Reindeer 

 Point (1479). 



Dupontia Fisheri, R. BR. 



D. Fisheri, SIMMONS, Fl. Ellesm.; D. psilosantha, RUPRECHT, Fl. 

 Samojed. cisural. [D. psilosantha., BESSELS, Amer. Nordpol-Exp. ; NAT- 

 HORST, Nachtr.]. 



This grass has been identified by ASA GRAY in Dr. BESSELS' col- 

 lection, and thus another locality added to its sporadic distribution in 

 the arctic regions, I am, however, inclined to think, that it may often 

 be sterile and therefore may easily be overlooked. 



Occurrence. N. Hall Land (BESSELS). 



Distribution. To the statements included in my Fl. Ellesm., 

 p. 161, must be added JNorth-Eastern Greenland. 



Poa glauca, VAHL. 



P. glauca, SIMMONS, Fl. Ellesm. [P. glauca, NATHORST, N. W. 

 Gronl.; P. caesia, DICKIE, Not. fl. pi., in INGLEFIELD, Summer Search]. 



I do not hesitate to pronounce this grass to be one of the most 

 common plants of N. W. Greenland, notwithstanding that it is absent 

 from the list of most collectors. This must, however, be because they 

 have confounded it with others, or have totally overlooked it. Neither 

 HART nor HAYES, for instance, have noted it for Foulke Fjord, where 

 it is extremely common and appears both in the typical form and in the 

 varieties elatior, (ANDERSS.) LANGE, and tenuior, SIMM. Of the latter I 

 found a few individuals only, in fissures of the rock at Reindeer Point 

 (1467); the former I found in abundance in large luxuriant tufts on the 

 manured soil of Etah (235); the main form I found in various local- 

 ities such as slopes, rookeries, etc.
