The genus Suaeda (Chenopodiaceae) in Canada

Abstract

The taxonomy of Suaeda spp. occurring in Canada has been studied. It is concluded that four species are present: Suaeda moquinii (Torrey) Greene, S. calceoliformis (Hook.) Moq., S. maritima L., and S. rolandii I. J. Bassett & C. W. Crompton sp.nov. Suaeda moquinii (2n = 18) is only known from the badlands of Saskatchewan and Alberta; S. calceoliformis (2n = 54) is widespread across Canada; S. maritima (2n = 36) is mostly present along the Atlantic coastline; S. rolandii (2n = 90) is found only in Quebec, New Brunswick, and Nova Scotia. Suaeda maritima spp. richii comb. nov. is rare in eastern Canada. Several names applied to these taxa are discussed.
