--><span class="statement" id="st-undefined" data-properties=""><b>Herbs </b>or shrubs, annual or perennial, monoecious or dioecious, often with bladderlike hairs that collapse to form silvery or scurfy (mealy) vesture, less often with elongate trichomes. <b>Leaves</b> persistent or tardily deciduous, alternate, partially opposite, or opposite, sessile or petiolate; blade entire, serrate, or lobed, with venation either of Kranz-type or normal dicotyledonous type, axillary buds inconspicuous or lacking. <b>Inflorescences</b> axillary or terminal; flowers borne in axillary clusters or glomerules, or in terminal spikes or spicate panicles. <b>Staminate</b> flowers with 3–5-parted calyx, ebracteate; stamens 3–5. <b>Pistillate</b> flowers lacking perianth, pistil naked, or in few species with (1–)3–5-lobed perianth, commonly enclosed within pair of foliaceous bracteoles; stigmas 2. <b>Fruiting</b> bracteoles enlarged in fruit, of various shapes and variously connate or not, thickened, and appendaged; pericarp free, tightly enclosed in the fruiting bracteoles. <b>Seeds</b> flattened, mainly vertical; radicle inferior, lateral, or superior. <b>x</b> = 9.</span><!--

|discussion=<p>Species ca. 250 (62 in the flora).</p><!--
--><p>Many species of Atriplex are halophytic, others occupy soils low in dissolved particulates.</p><!--
--><p>Prior to the 1900s, the genus Suckleya was treated within Atriplex, but its obcompressed fruiting bracteoles are quite unlike anything in Atriplex, and the plants were recognized as a distinct genus.</p><!--
--><p>Excluded species:</p><!--
--><p>Atriplex barclayana subsp. dilatata H. M. Hall & Clements, Publ. Carnegie Inst. Wash. 326: 315. 1923</p><!--
--><p>A new species, most related to Atriplex argentea and A. expansa, judging from the habit; but the fruits are flat and their sides not appendaged or muricate.” The plant was described from San Benito Island, Baja California.</p><!--
--><p>Atriplex nitens Schkuhr, Bot. Handb. 3: 541. 1803</p><!--
--><p>P. C. Standley (1916) reported this species in New York, New Jersey, South Dakota, and Oregon.</p><!--
--><p>P. Aellen (1964) wrote: “Like 4 [i.e., A. hortensis] but the leaves white beneath; bracteoles oblong-cordate, conspicuously reticulate-veined.” Specimens having at least some of the above noted characteristics occur here and there among the North American materials of A. hortensis, and the name nitens is here in considered in synonymy of that species. It belongs to sect. Atriplex.</p><!--
--><p>Atriplex nodosa Greene, Pittonia 1: 40. 1887</p><!--
--><p>This name was apparently not taken up, even in synonymy, by either L. Abrams and R. S. Ferris (1923–1960, vol. 2) or P. A. Munz (1959), but was cited as a synonym of Atriplex argentea by P. C. Standley (1916). H. M. Hall and F. E. Clements (1923) cited this as a synonym of “A. argentea expansa,” based on “An insect stung monstrosity, according to Jepson (Fl. Calif. 436, 1914).”</p><!--
--><p>Atriplex sibirica Linnaeus, Sp. Pl. ed. 2, 2: 1493. 1763</p><!--
--><p>This was supposedly collected in northeastern United States, but no specimens have been seen from the flora area. It belongs to sect. Obione.</p><!--
--><p>Atriplex vesicaria Heward ex Bentham, Fl. Austral. 5: 172. 1870</p><!--
--><p>The section Dialysex, to which Atriplex vesicaria belongs, is treated in the Australian flora with sixteen species; A. vesicaria with eight subspecies; its records in the United States, if any, are not known to me. It would not, in any case, be treated with the herbaceous species. H. M. Hall and F. E. Clements (1923) noted that this species, and the related A. holocarpa, have both been grown in American gardens with the thought of using both of them as forage plants, but neither of them found suitable for general planting.</p>
