38 Morren P. Porsitp 
Vv 39. Dechampsia caespitosa (L.) Beauy. var. pumila Lepes. 
On moist sandy clay, sometimes almost submerse on lake-shores: 
very rare. 
Disko: Godhavn 65°14’ near Udkiggen (Rikli; P.); the west coast (Wethe- 
rill); the north coast: Gieseckes Dal, 70°15’ (P. 1902 det. C. H. Ostenretp: Medd. 
om Gronld. 43 p. 13, re-found 1916 P.). Hare © (Nath.). 
A decided northern type, the above mentioned localities repre- 
senting the south limit; for the rest only known from a few localities 
on the coast of East- and West Greenland (Cf. Osrenrecp, |. ¢. and 
Porsitp Medd. om Gronld. 50, p. 365). 
On land abundantly flowering and fruiting, being only rarely sub- 
merse. 
Hibernates covered by snow and ice. 
A 40. Deschampsia alpina (L.) R. & Scu. (Syn. Aira caespitosa 
v. borealis TRAUTV.). 
A pronounced southern type common south of 64° and only 
known from a few localities in the southmost part of the area. 
The region of Holsteinborg 66°55’ (Th. Fr.); S. Kangerdluarssuk about 67° 
(W. & H.); Eqaluarssuit in N. Stramfjord 67°36’ (P. & E.) several places on sandy, 
clayey riverbanks. 
The last mentioned locality for the present the north limit. 
The species was here abundantly flowering, but viviparous. Every- 
where we found spikes a year old weighed down by the early fall of 
snow, the bulbils being not yet ripe and ready for dispersal. Several 
of the specimens had preserved their power of germination, but the 
power of migration of the species seemed to be lost. 
I 41. Trisetum spicatum (L.) Beauv. 
On fell-field, clefts, vigorous heath, herb-mats, thickets, strand- 
dunes, often in manured soil at the houses and below fowling cliffs 
(f. villosisstma Lge.), but not on newly-formed moraine; f. Javior Lange 
is a shade-form from thickets. 
Very common throughout the whole area. 
Neither southern nor northern limit in Greenland. 
No doubt ascending the hills to the snowline, but not among the 
pioneers of the newly-formed moraine. 
Abundantly flowering and fruiting. 
Undoubtedly always covered by snow during winter.
