--><span class="statement" id="st-undefined" data-properties=""><b>Stems </b>sparsely branched, 3–8(–10) dm; branches very stout, obtusely angled, sparsely scurfy when young. <b>Leaves</b> mostly alternate; petiole (0.5–)1–2(–2.5) cm; blade bright green, oblong to lanceolate or hastate-lanceolate or -ovate, 20–90(–125) × 8–60(–70) mm, base rounded to cuneate, with proximal lobe often the largest and antrorse, margin entire or repand-denticulate, apex obtuse or acute, sparsely scurfy when young, becoming more slender and usually entire upwards. <b>Flowers</b> in short, dense, usually leafy, axillary or terminal spikes and in axillary glomerules, staminate ones 4-merous. <b>Fruiting</b> bracteoles sessile, oblong to ovate-orbiculate, or ovate to triangular, sometimes broader than long, 4–14 mm, united only at rounded base, margin entire or with (1 or)2 or more teeth, apex acute or acutish, or sometimes rounded, faces not appendaged, only apex foliaceous. <b>Seeds</b> dark brown (no black seeds observed), 2.8–3.5 mm broad; radicle inferior to subascending.</span><!--

|discussion=<p>I. J. Bassett et al. (1983) distinguished this at species level from the closely allied <i>Atriplex gmelinii</i> by sizes of brown seeds, i.e., 1.7–2.7 mm wide, <i>A. gmelinii</i>; and 2.8–3.7 mm wide, A. alaskensis. Some seeds of plants clearly belonging to <i>A. gmelinii</i> bear seeds as much as 3 mm wide, so the distinction in seed size is not absolute. Also, <i>A. gmelinii</i> occasionally bears black shiny seeds, which have not been observed in specimens of A. alaskensis. It is unfortunate that many collections appear to be juvenile plants lacking mature fruiting bracteoles and seeds. The A. alaskensis phase occurs completely within the range of <i>A. gmelinii</i> and might represent no more than a growth phase of the latter species. Certainly there is considerable ecologically induced variation within the gmelinii complex. Plants that grow within the littoral zone, where they are inundated by high tide, present completely different facies than do those that are immediately above the tidal zone. Leaves vary from linear to oblong, oval, and various other shapes within what has been traditionally regarded as <i>A. gmelinii</i> in a strict sense (<i>A. patula</i> <i></i>var.<i> obtusa</i>). The two entities, <i></i>var.<i> gmelinii</i> and <i></i>var.<i> alaskensis</i>, are treated herein as belonging to an inclusive <i>A. gmelinii</i>.</p>
