petiole 0.2–2.5(–3.5) cm;
blade all entire or some or all triangular or lance-hastate with lobes spreading to antrorse, 5–100 × 3–80 mm, base abruptly to narrowly cuneate, entire or irregularly toothed.

Atriplex glabriuscula
Atriplex parryi
Varieties 3 (3 in the flora).
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.

Atriplex parryi occurs with greasewood, saltbush, saltgrass, and Nitrophila. The cordate-clasping, sessile leaves and spiny branches distinguish this species from its nearest congeners.
