heather which here shows many examples of transitions from the most 
common Myrtillus heath with Loiseleuria, Phyllodoce and Ledum to the 
less common, almost pure Empetrum heath. On July 12th both Myr- 
tıllus and Empetrum were covered with ripe berries. 
Moreover all the northern Crucifere and Composite were absent, 
even such as Lesquerella, Braya, Arabis arenicola and Erigeron compositus 
and eriocephalus which were common at Atanikerdluk. 
The following new and additional species may be mentioned: 
Juncus supinus which has only been recorded a few times from Green- 
land and previously not north of 68739"; Potamogeton filiformis and 
Arnica alpina п. f. inundata growing in the stiff clay of a desiccated 
pond which probably contained water during the greater part of the 
season. It looked most curious and had developed long, horizontal under- 
ground shoots, some exceeding one meter. Nearly all the specimens 
were sterile and resembled a broad-leaved Luzula. 
From Sarqaq we visited Naujat in an Umiaq and here perhaps, 
I saw the most luxuriant vegetation met with in the course of the whole 
trip. Near the landing place Arabis Holboelli, and Draba aurea abounded 
together with Antennaria intermedia and probably a new species of the 
same genus. 
Behind the coast cliffs of tufa and basalt a depression is occupied 
by a swampy valley with a series of small lakes and ponds all more 
or less overgrown by an occasionally floating carpet of vegetation in 
which Carices and Eriophore as high as one metre played a most con- 
spicuous part, together with a low scrub of willows which seldom occur 
in such places. This treacherous border of the swamps was very difficult 
to approach and only by stripping was it possible to get near the edge. 
By means of an apparatus constructed of my photographic tripod and 
a pickaxe I was fortunate enough to dredge up a few interesting aquatic 
plants: Potamogeton filiformis and groenlandicus, Sparganium submuticum, 
Callitriche autumnalis, Hippuris, Ranunculus confervoides and Heleo- 
charis acicularis {. submersa. 
A couple of loons had obviously nested among the willows: mosses 
were brought up from the edge and amongst them I saw numerous 
specimens of а Limn&a (probably Vahlit or Holboelli), a very scarce 
animal on this latitude. In a small pond near the shore I found numerous 
sterile specimens of Ranunculus reptans. 
In the evening we returned to Sarqaq and from there proceeded 
for Godhavn via Ritenbenk and Jacobshavn.
