Stellaria crassifolia

Note that the answers to the keys to the species listed below include requirements that the leaves be long and narrow.  These actually apply to just the upper leaves; the lower ones are shorter and broader.

Budd's Flora requires the leaves to be 6-20 mm long, not 2-8 mm long and 2-6 mm wide, not 1-4 mm wide in order to distinguish S. crassifolia from S. humifusa.  The leaves of this specimen don't all closely match this, but in the prairie provinces the only place to find S. humifusa is on sandy beaches along Hudson Bay (the ocean, not the town, in northern Manitoba) so there should be no confusion.
