These tAvo 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.

Lge. Consp. Fl. Groenl. p. 250, Berlin Kärlväxter 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 sihques 1,5 — 2,8 mm. long, с 1,5 

 — 2 mm. broad, 1 — 1,5 mm. thick with up to 6 hght brown seeds.
