Morten P. PORSILD. 
Widely distributed in West-Greenland, rather a northern type, 
on the west coast becoming scarce south of 64°, and on the east coast 
it seems to be very rare south of 69°. 
| Note: P. radicatum no doubt includes several small species as 
already indicated by Simmons and others. The white-flowered variety 
is common far into the north, but very rare, already in our area. On 
account of its occurence in patches and for other reasons, too, it seems 
to be hereditary constant. 
Flowers and fruits abundantly. Many fruits are devoured before 
ripening by birds, for instance ptarmigans and snow-buntings. 
Hibernates often snowless. 
XXII. Cruciferae. 
| 161. Cardamine bellidifolia Г. (С. sinuata (VAHL) ROWLEE 
& WIEGAND). 
On moist sand and clay, in fell-field and new moraine; bare spots 
on the heath, rarer among grasses in manured soil. 
Throughout the whole area from the coast to the snow-line, but 
from relatively few places; undoubtedly not because of being rare, 
but only overlooked. 
Widely distributed in Greenland although rather a northern 
type; in the southmost part of Greenland only exceptionally from the 
lowland (Ros.). 
Abundantly flowering and fruiting. 
Undoubtedly covered by snow during the winter. 
i 162. Cardamine pratensis L. var. angustifolia Hook. 
In moist moss-bogs, at the borders of small lakes often partly 
submerse; sometimes in shallow brooks. | 
Distributed through the whole area, most frequent in the southern 
part, but nowhere common. Now and then occurring in small patches. 
Widely ranging in Greenland without southern limit; and no 
doubt without northern limit, too, being found far north into Elles- 
mereland. The scattered occurrence is no doubt due to the fact that 
the plant does not fruit anywhere in Greenland, but disperses itself 
only in vegetative manner, by deciduous leaflets. | 
Usually flowering, though hardly in unfavourable places. 
The flowering is specially dependent on the time of the melting 
of the snow.
