canescens, Erigeron compositus and besides the very rare, high-arctic 
Poa abbreviata. 
А small tributary to the river of Qaersuarssuk flows in a slight 
depression through this plain and has given rise to a boggy stretch of 
hummocks where Arctagrostis, and Carices abound. On small hummocks 
covered with moss I found for the second time the rare Eutrema. The 
plants were scattered and had finished flowering. During one hour’s 
eager search I only found a dozen specimens of which none were so 
vigorous as the specimens described by Ровзи (19, р. 376). 
Ata place named Agiussuit we stopped two days to collect fossils 
and during the whole trip I never saw a place so barren and devoid 
of vegetation. On the sandy slope near the inlet of a small ravine the 
total flora observed comprised 8 vascular plants: Festuca brevifolia, Poa 
abbreviata, Cerastium alpinum var., Salix glauca, Papaver radicatum, Poly- 
gonum viviparum, Chamaenerium latifolium, Taraxacum phymatocarpum, 
and some Lichens. It was therefore rather astonishing to see a butterfly 
resting on one of the prostrate twigs of a Salix which had already 
finished fruiting. 
At Niaqornat we only stopped a few hours to replenish our stock 
of coffee and water and I therefore could not make extended excursions. 
Across the sheltered bay to the eastward of the protruding headland 
of Niagornat the strong current has deposited a narrow strip of sand 
which has caused the formation of a shallow lagoon apparently without 
vegetation except some Algae which have coloured the water of the 
lagoon light green. 
The Settlement seen from the low hills to the South, situated 
between the low tufa hummocks behind the headland covered with the 
vermilion-coloured Lichen, Xanthoria elegans, and reflected in the green 
lagoon, made a very picturesque scene. 
From Niagornat we visited the trading place of the same name 
as the peninsula, and, for the second time, called at Hare Ø before 
we landed at Alianaitsinguak on Aug. 4th for the night. The coast 
is here formed by tufa strewn with glacial boulders. Some sixty meters 
above sea-level some springs had formed a verdant slope. Amongst tall 
grasses large specimens of Cochlearia abounded. As a rule Cochlearias 
are seldom met with outside the halophilous vegetation belt of the 
strand and on bird-cliffs. 
At Atå and Pâtût we spent several days in search of fossils. At 
Pätüt, together with Mr. Нотлтом, I climbed to the uppermost sedi- 
mentary strata and there, on a 100 m. broad terrace 670—770 m. above 
sea-level, compiled a list of plants as complete as possible. HArrz (4, 
p. 49) describes the vegetation of the mountain slope at this locality
