Recorded distribution of Spergularia taxa in Saskatchewan. seems to hold reasonably well for the available Saskatchewan specimens. Such a tendency, at least, seems apparent, although floral bract length could hardly be used as a sole distinguishing character. The two varieties may be separated by use of the following taxonomic key: Key to Varieties of Spergularia marina in Saskatchewan la. Seeds smooth-surfaced, lacking glandular- papillae; middle floral bracts mostly 4 mm long or more; inflorescence usually appearing more open, leafy, and not well differentiated from lower plant portions var. leiosperma (Kindb.)

Seeds ± densely glandular-papillose; middle floral bracts mostly shorter than (-5) mm long; inflorescence usually appearing more congested and better differentiated from lower plant portions var. marina Spergularia marina var. marina [synonyms: S. salina J. & C. Presl.; S. sparsifolia (Greene) A. Nels.], with glandular-papillose seeds, has been verified in Saskatchewan from near Dana (30 July 1937, R. C. Russell, DAO, SASK, SCS); Tisdale (29 July 1940, A. J. Breitung #804, DAO); vie. Pakwaw Lake Village, Shoal Lake Indian Reserve, (9 Sept. 1983, R. R. Hooper#83-09-09-02, SASK; 18 July 1984, V. L. Harms, D. F. Hooper & L. Baker #32851, SASK); and near Meacham (6 Aug. 1986, J. Kranabetter #70, SASK) (see Figure 1). Records of the typical variety marina appear lacking in Saskatchewan from west and south of the general Saskatoon area, but the author has personally seen papillose-seeded specimens from even farther west in northeastern Alberta (Mamawi Lake, 24 Aug. 1969, D. & K. Dabbs300, SASK), and Rossbach( 1940) also cited such plants from Wood Buffalo Park. Spergularia marina
