Lge. Consp. Fl. Groenl. p. 105, Berlin Kärlväxter p. 60, 
Hartz Fanerog. p. 392. 
Commonly distributed in all formations as well on the coast 
as in the interior. Appears in two forms connected by transitions: 
a. vulgaris. On herby slopes and in copses in sheltered lo- 
calities. The rhizome as a rule not swoln, 5—7 etm. long, s-for- 
med curved at the top, closely covered with brown ligules and 
short rests of Jeaf stalks. Most often 2 stems, 20—30 ctm. long. 
The inflorescence 5—9 etm. long, with bulbs on the lower 2/3. 
Flowers in July. The flowers white-pink. The bulbs are eagerly 
searched by Emberiza nivalis. 
2. alpina. Whe. fl. Lappon. In table-land and heath. The 
rhizome short, 2—3 ctm., strongly s-formed, bent double, swoln, 
up to 1 etm. thick, only at the point set with 2 ctm. long leafstalks. 
The stem 5—10, exceptionally 20 ctm. high; the ground leaves 
{—5ctm. long, 0,5—3ctm. broad oval. The inflorescence 2—-6 ctm. 
long with bulbs on the lower half part. The flowers pink, the 
flowering begins on the 20 of June and is continued in shady 
localities until the beginning of the frost. 
Note. The tubers are eaten by the natives. 
110. Oxyria digyna Campd. 
Lge. Gonsp. Fl. Groenl. p. 105, Berlin Kärlväxter p. 59, 
Hartz Fanerog. p. 392. 
Commonly distributed in table-land, herby slopes, copses of 
willows, manured places and cracks in the rocks as well on the 
coast as in the interior; found at all heights above the level of 
the sea. 
5—50, commonly 20 ctm. high; thickly tufted with numerous 
rests of old leaf-stalks round the top of the many headed rhizome. 
The leaf-stalks 1—20 ctm. long, the blade 1—5 ctm. broad. Flowers 
from the 20 of June until September, sets abundant ripe fruit. 
Seedling plants and young specimens are most frequently found. 
The great variations of the size of the plant are due to the wide 
extent of the habitat of the plant, the smallest specimens are found 
in stony plains and in table-land. The great specimens are restricted 
to the copses.
