Higher Taxonomy
Common Name: GOOSEFOOT FAMILY Habit: Annual to shrub; hairs simple, stellate, or glandular; plants in several genera scaly, mealy, or powdery from collapsed glands; monoecious, dioecious, with bisexual flowers, or with both bisexual and unisexual flowers. Stem: occasionally fleshy. Leaf: blade simple, generally alternate, occasionally fleshy or reduced to scales, veins pinnate; stipules 0. Inflorescence: raceme, spike, catkin-like, spheric head, axillary clusters of flowers, or flowers 1; bracts 0--5, herbaceous, generally persistent or strongly modified in fruit, wings, tubercles or spines present or 0. Flower: bisexual or unisexual, small, generally green; calyx parts (1)3--5, or 0 in pistillate flowers, free or fused basally (or +- throughout), leaf-like in texture, membranous, or fleshy, deciduous or not, often strongly modified in fruit; corolla 0; stamens 1--5, opposite sepals, filaments free, equal; anthers 4-chambered; ovary superior (1/2-inferior), chamber 1; ovule 1; styles, stigmas 1--4 (or stigmas sessile). Fruit: achene or utricle, generally falling with persistent calyx or bracts. Seed: 1, small, lenticular to spheric; seed coat smooth to finely dotted, warty, net-like, or prickly, margin occasionally winged. Genera In Family: 100 genera, 1500 species: worldwide, especially deserts, saline or alkaline soils; some cultivated for food (Beta vulgaris subsp. vulgaris, beet, Swiss chard; Spinacia oleracea L., spinach; Chenopodium quinoa Willd., quinoa); and some worldwide, naturalized ruderal or noxious agricultural weeds. Note: Nitrophila treated in Amaranthaceae, Sarcobatus treated in Sarcobataceae. Key to genera revised by Elizabeth H. Zacharias to incorporate Extriplex and Stutzia, 2 genera segregated from Atriplex. Native spp. of Kochia now treated in Neokochia. Chenopodiaceae often treated now within a more broadly circumscribed Amaranthaceae (Morales-Briones et al. 2021). eFlora Treatment Author: Mihai Costea, family description, key to genera, revised by Thomas J. Rosatti & Elizabeth H. Zacharias, except as noted Scientific Editor: Bruce G. Baldwin, David J. Keil, Thomas J. Rosatti, Margriet Wetherwax.

Stutzia
Habit: Monoecious annual, generally scaly. Leaf: alternate, distal +- reduced; blade entire to lobed; non-Kranz. Inflorescence: axillary or terminal. Staminate Inflorescence: spheric cluster in distal axils, dense or interrupted spikes, often mixed with pistillate flowers; bracts 0. Pistillate Inflorescence: solitary or 2--6 in axils of midstem leaves; bracts 2 per fruit, enlarged in age, fused to above middle [fused to top], generally compressed, generally sessile or stipitate, falling with fruit. Staminate Flower: calyx lobes 5; stamens 5. Pistillate Flower: calyx present; stigmas 2. Seed: generally erect. Species In Genus: 2 species: western North America. Etymology: (Howard Stutz, North American geneticist who resurrected Endolepis Torr., 1918--2010) Note: Previously included in Atriplex. Jepson eFlora Author: Elizabeth H. Zacharias, as part of Atriplex Reference: Zacharias & Baldwin 2010 Syst Bot 35(4):839--857. Index of California Plant Names (ICPN; linked via the Jepson Online Interchange)
