Comments

Members of the Atriplex glabriuscula complex occupy saline or brackish marshes and saline coastal strands mainly in the eastern maritime provinces of Canada, with extensions in similar habitats into the northeastern United States. They are seldom, if ever, ruderal weeds and appear to be indigenous or perhaps early introduced in some part from similar European habitats. The constituent taxa have been regarded at specific level (P. M. Taschereau 1972; I. J. Bassett et al. 1983). They are, however, alike in all major morphologic features, and are apparently closely allied. For those who wish to treat them at specific level, the names are supplied in the synonymy.
