Kochia scoparia subsp. scoparia

Higher Taxonomy
Family: ChenopodiaceaeView DescriptionDichotomous Key

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.

Genus: KochiaView DescriptionDichotomous Key

Habit: Annual to subshrub, generally erect, glabrous to tomentose. Leaf: alternate or lower +- opposite, +- thread-like to lanceolate, flat to cylindric, fleshy or not. Inflorescence: spikes, simple or branched; bracts leaf-like; flowers 1--7 per axil. Flower: bisexual or pistillate, sessile; calyx lobes 5, incurved, keeled; tubercled, winged or not in fruit; stamens 5; stigmas 2--3. Fruit: +- compressed-spheric. Seed: horizontal.
Species In Genus: +- 15 species: western North America, Eurasia. Etymology: (Wilhelm D. Koch, German physician, botanist, 1771--1849) Note: Native species recently treated in Neokochia, Kochia scoparia in Bassia.

Kochia scoparia (L.) Schrad. subsp. scoparia
Habit: Annual 20--120 cm. Stem: simple to much-branched, glabrous to spreading-hairy. Leaf: 8--50 mm, 1--6 mm wide, flat, glabrous to appressed-hairy, generally 3--5-veined below middle. Inflorescence: branched spike, short- to densely long-hairy, hairs < to > flowers; flowers 1--7 per axil; hairs generally hiding flowers in immature inflorescence. Flower: calyx glabrous to thinly appressed-hairy, lobe margins generally bristly (glabrous); bisexual flowers with tubercles or wings < 2 mm in fruit.
Ecology: Disturbed places, fields, roadsides; Elevation: < 2300 m. Bioregional Distribution: CaR, SN, GV, n SnFrB, SCo, SnBr, GB, D; Distribution Outside California: to eastern United States; native to Eurasia. Flowering Time: Aug--Nov Note: Immature plants much like Bassia hyssopifolia (Pall.) Kuntze. If recognized taxonomically, a cultivated form with linear to thread-like leaves, short internodes, inflorescence hairs < flowers, rarely escaping in SnJV, SCo (expected elsewhere), assignable to Kochia scoparia subsp. culta (Voss) O. Bolòs & Vigo. Other subspecies in Eurasia.
