As with Plantago maritima, the Spergularia canadensis plants were associated with the somewhat elevated areas of saline springs and associated pools surrounded by broad marsh flats. That the salinity of this and other Carrot River valley salt-marshes is mainly due to their sodium chloride content rather than to sodium sulfate characterizing most Saskatchewan saline lakes and marshes, may be a significant factor in the occurrence of these unique species here. Because of the unexpectedness of our discovery of Spergularia canadensis var. occidentalis in east- central Saskatchewan, with its exceptional disjunction and "non-maritime" occurrence here, we delayed for some time the publication of this new provincial record until it could be carefully rechecked and compared with verified specimens from the Pacific Coast. This was done in conjunction with a broader study of variation in all Saskatchewan Spergularia species. It is with reasonable confidence that we now publish this new provincial record in the belief that our Nitenai River plants fit well into S. canadensis var. occidentalis and, in fact, this appears to be the only known taxon in North America into which they could be placed. Other Possible Species Besides the three, foregoing, sand-spurrey species that have been verified for Saskatchewan, possibly two other species, both more weedy introductions from Eurasia, could yet be encountered in the province, although their apparent absence even in adjacent provinces and states makes this unlikely. Spergularia rubra (L.) J. & C. Presl. (Purple Sand-spurrey), an apparent introduction from Europe, has a known distribution along the.
