--><span class="statement" id="st-undefined" data-properties=""><b>Herbs,</b> much branched, forming tangled or spreading masses. <b>Stems</b> with branches divaricate or ascending, terete or obtusely angled, 2–10(–15) dm, sparsely scurfy when young. <b>Leaves</b> alternate (or the proximalmost opposite), long petiolate becoming nearly sessile distally, blade ovate to triangular, 15–50(–60) × 10–40 mm, base subhastate or cuneate, margin deeply or shallowly sinuate-dentate with acute or obtuse teeth, apex acute or obtuse, distalmost bracteate blades becoming entire and linear or oblong-linear. <b>Staminate</b> flowers in glomerules borne in slender, naked or sparingly bracteate (at base), mostly interrupted simple or paniculate spikes, calyx 5-cleft. <b>Pistillate</b> flowers fascicled in distal axils. <b>Fruiting</b> bracteoles strongly 3-veined and reticulate, sessile or short stipitate, ovate-rhombic or subflabelliform, 4–8 × 3–7 mm, moderately compressed, united from narrowed base to middle, margin broad, foliaceous, coarsely dentate, indurate at maturity, faces tuberculate or smooth. <b>Seeds</b> brown, 1.5–2 mm; radicle inferior, ascending.</span><!--

|discussion=<p>H. M. Hall and F. E. Clements (1923) treated <i>Atriplex tatarica</i> at specific level with the above distribution (as an introduced ballast plant of rare occurrence), but did not recognize the closely similar <i>A. laciniata</i>, which is currently the species recognized for coastal eastern America. They evidently interpreted <i>A. tatarica</i> to include A. lampa Gillies as identified by P. C. Standley (1916). <i>Atriplex</i> lampa is a shrubby species from South America and does not figure in consideration of North American taxa. <i>Atriplex tatarica</i> includes a complex of forms and varieties in Flora URSS (M. M. Iljin 1936). In Flora Europaea (P. Aellen 1964b) <i>A. tatarica</i> and <i>A. laciniata</i> are separated in the key by the glomerules of <i>A. tatarica</i> being borne in terminal, leafless, often long panicles, whereas those of <i>A. laciniata</i> are borne axillary or in leafy clusters. The species differ otherwise in stature, <i>A. laciniata</i> being a dwarf plant up to 30 cm and with small leaves, <i>A. tatarica</i> being a robust annual up to 150 cm, and with large leaves. The illustration by Hall and Clements (fig. 38) shows a plant with leafy panicle.</p><!--
--><p><i>Atriplex tatarica</i> has been ignored by H. A. Gleason and A. Cronquist (1991) and by all other authors of floras covering the northeastern United States.</p>
