of our area, where it is very scarce. Hence it must be considered a south- 
ern type in West Greenland. 
Not knowing P. retroflera and its several forms myself, J cannot 
add any observations as to its occurrence. 
About the remaining plants contained in the »Glyceria distans« of 
GeLERT see the following nurabers 54—56. 
Vv 54. Puccinellia angustata (RK. Br.) Rann & Repr. 
At the sea-shore but also intermingled in the not-halophilous vegeta- 
tion or occurring on the peat from previous land-vegetation now killed 
by the salt water; besides in all the places which agree with the var. 
raginata and together with this variety. 
A northern type, rather common on the coasts of Waygat. Besides from 
numerous localities around Disko-Bay becoming scarcer down the archipelago of 
Egedesminde; the southern limit is about 67°. 
Abundantly flowering and fruiting. 
Hibernates covered by snow. 
Vv 55. Puccinellia angustata var. vaginata (LANGE). 
Hormps. hoe loco! 
The most common Puccinellia in our area. 
At the sea-shore, mostly on clayey, moist-sandy ground, or among 
other strand-vegetation; normally forming semi-globular cespits and the 
straw decumbent and closely pressed to the ground. Stands manuring 
very well, and in exceedingly manured soil, for instance at settlements 
or on small fowling-islets the tufts become hummocky and the newly 
hatched youngs of gulls and terns are able to hide in the channels 
under the leaves of the cespits. 
Very common throughout the northern part of the area. 
Like the preceding a northern type. 
Flowers and fruits in great abundance. 
Hibernates covered by snow and often by ice. 
A 56. Puccinellia arctica (Hook) Fern & WEATH. 
By this name I understand a rather coarse grass, habitually 
differing widely from the preceding by its erect growth. It occurs 
on plains, raised marine clay, on clayey sandy terraces at the head of 
fjords and along the banks of the rivers falling into these. 
Much scarcer than the preceding species because of the absence 
of suitable places; but covering extended areas when occurring, though 
not forming dense carpets as the foregoing.
