DISTRIBUTION AND OCCURRENCE
SPECIES: Drosera rotundifolia | Round-Leaved Sundew 



GENERAL DISTRIBUTION : 
Round-leaved sundew is distributed from Greenland and Newfoundland west
to Alaska.  It occurs south along the Pacific coast to California and
inland as far as western Montana and western Colorado.  In the East,
round-leaved sundew is found from Nova Scotia south to Georgia, Florida,
and Alabama and west to the Mississippi River, Iowa, and Minnesota
[14,19,21,44,45].  Round-leaved sundew is known from at least two
locations in west-central Montana [32].  In Colorado, it is known from
one bog in Gunnison County, a site that has been given special
protection [60].  There is also one record of round-leaved sundew from a
bog in Bottineau County, North Dakota [64].  Populations of round-leaved
sundew also occur in Europe and Asia [21,22,44].
