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.
Common Name: PIGWEED, GOOSEFOOT Habit: Annual or perennial herb, glabrous or powdery. Stem: branches 0 to generally erect (spreading). Leaf: generally petioled; blade linear to deltate or diamond-shaped, entire to lobed or toothed, reduced distally on stem; proximal leaves generally early-deciduous. Inflorescence: spheric clusters or flower 1, in spikes, or panicle-like, generally dense; bracts generally 0; flowers generally sessile. Flower: sepals generally 5, fused or not, persistent, flat to keeled; stamens generally 5; stigmas 2(5). Fruit: enclosed or subtended by calyx; fruit wall membranous or papery, free or attached to seed and generally loosening in age. Seed: vertical or horizontal, lenticular to +- spheric, red-brown to black; wall thin. Etymology: (Greek: goose foot, from leaf shape of some species) Note: Fruit generally required for identification. Other species in TJM (1993) now treated in Dysphania. Unabridged Note: Powder on plants from small, inflated hairs. eFlora Treatment Author: Steven E.

Chenopodium berlandieri Moq.
NATIVE Habit: Annual 10--60 cm, generally not scented. Leaf: blade 15--30(40) mm, lanceolate to +- diamond-shaped, ovate, or +- deltate, generally with 2 lobes near base and serrate to irregularly toothed or entire, powdery. Inflorescence: clusters, in branched spikes 5--17 cm. Flower: sepals ovate to deltate, powdery, strongly keeled abaxially, enclosing fruit in age. Fruit: 1--1.5 mm diam; wall attached to seed, brown, honeycomb-pitted at 20×. Seed: horizontal; seed coat black, honeycomb-pitted. Chromosomes: 2n=36. Note: Generally confused with Chenopodium album.

(Note: any qualifiers in the taxon distribution description, such as 'northern', 'southern', 'adjacent' etc., are not reflected in the map above, and in some cases indication of a taxon in a subdivision is based on a single collection or author-verified occurrence).
MAP LEGEND View all CCH records All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
