f. contorta Ehrh. 
silicula glabra contorta, foliis omnibus integerrimis (vel caulinis 
rarius unidentalis). C. 15 ctm. alt. 
Akiliarisek. 
These two forms are constant in the material before me, but 
they cannot be kept from each other in the remaining arctic ma- 
terial accessible. All transitions are on the contrary found here. 
*Brassica campestris L. 
Introduced with food for hens. Was found in great quantities 
round the landing place of the trading station and grew in a mixture 
of mould and barley corn. Flowered richly in July—August. Seeds 
not observed. 
*Sinapis arvensis L. 
Introduced with food for hens. Was found in several places 
near the colony, partly in kitchen-middens, partly at the landing 
place, but single specimens were also seen on original soil and 
attained there a height of 40 ctm. Flowered richly in July— August. 
Seed not observed. 
45. Subularia aquatica L. 
Lge. Consp. Fl. Groenl. p. 250, Berlin Karlvaxter p. 26. 
In ponds on sandy ground covered with a layer of mud, 1 ctm. 
thick, is found both submerse and on dried up ground, the largest 
depth of the water is 40 ctm. It flowers in the middle of August. 
Developped flowers were not taken but above the water; all sub- 
merse specimens had buds, but no open flowers. Fruit was found 
in abundance on the 10%—the 15 of August, the seeds ripe. The 
specimens grow gregariously in great numbers, but still with large 
intervals, forming no cover. They are 1—1,5 ctm. high with 3— 
5 strict leaves, 4—7 mm., exceptionally 15 mm. long; the peduncles 
are bent down, the bear 1 —3 flowers, of which as a rule only the 
oldest one (the lowest) sets fruit. The white petals are also found 
in the submerse specimens. The siliques 1,5—2,8 mm. long, c. 1,5 
—2 mm. broad, 1—1,5 mm. thick with up to 6 light brown seeds. 
Found only near Tasiusak. 
Pond at Elvbakker abt. 100 mt. above the level of the sea. Pond 
in Amaka abt. 3 mt. above the level of the sea. Kong Oscars Havn 
near the beach (Berlin)!
