desiccated borders preferably in the shade of overhanging Carer- 
tufts, but withers when exposed to long exsiccation. 
Seems in Greenland to be rare, but occurs widely distributed in 
isolated growths. 
Disko: The south coast, in Blasedalen (P.); Diskofjord: Evqitsog 69°30% 
(E. P.); Nordfjord: on the southern side of the mouth 69°55’ (P.). 
Mainland: Sargqaq about 70° (Th. Fr., re-found by E. P.): Taseralik 67°25” 
(E. P.); N. Isortog 67°10’ (V.); Holsteinsborg 66°55’ (V_): at the head of S. Stram- 
fjord (Jens.). 
In deeper water floating and sterile forms are common (cfr. Sim- 
mons: Uber einige lappl. Phanerog. Arkiv for Bot. 6, No. 17, p. 4; idem: 
Bot. Not. 1908 p. 121—128). 
A decided southern type, south of the area known from Godt- 
haabsfjord and a few localities between 60° and 62°. 
The north limit at Ikerasak 70°30' (Vh.). 
Ordinarily flowering and fruiting. 
Hibernates under or enclosed in ice. 
Agrostis canina L. 
Recorded from Egedesminde by Beruin (Ofyv. K. Vet. Ak. Forh. 
1884, No. 7, p. 76), but the author himself seems to doubt the correct- 
ness of his own determination. Probably confounded with the following 
species, otherwise only known from the west coast between 60° and 62°. 
A 32. Agrostis borealis Harrm. (A. rubra WAHL p. p.). 
In dry stony soil: dry rocky-flats, rarer on gravel and dry heath- 
vegetation. 
Disko: Common in the gneiss-domain of the south coast; strangely not 
found on basalt. 
Mainland: Common in the gneiss domain. especially southwards at some 
distance from the coast. . 
In the districts of Jakobshavn and Christianshaab the localities are 
situated at some distance from each other though rather numerous. 
Not found within the basalt and sandstone-domain of Nugssuaq. 
A southern type, north of the area found on Qaratsap-Nunata 
70°30’ and at the head of the fjords inland from Preven 72°30’ (Th. P.) 
this hitherto being the north-lmit. 
Ascends the favourably exposed hill-slopes to at least 500 m. 
Flowers and fruits abundantly. 
No doubt often without any cover of snow during winter.
