Bassia scoparia


Higher Taxonomy
Family: ChenopodiaceaeView DescriptionDichotomous Key
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).

Genus: BassiaView DescriptionDichotomous Key


Habit: Annual, generally hairy. Stem: axis generally erect; branches ascending to erect. Leaf: linear to lanceolate, reduced distally. Inflorescence: spike; bracts leaf-like; flowers 1--few per axil. Flower: generally bisexual; calyx lobes 5, incurved, hooked-spiny, tubercled, or winged in fruit; stamens generally 5; stigmas generally 2. Fruit: +- depressed-spheric. Seed: horizontal.

Bassia scoparia (L.) A.J. Scott
NATURALIZED
Habit: Plant gen 20--120 cm. Leaf: 8--50 mm, 1--6 mm wide, flat, glabrous or appressed- to appressed-spreading-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 Bassia scoparia subsp. culta (Voss) J.R. Nebot, A De la Torre, G. Mateo & F. Alcaraz. Other subspecies in Eurasia.

Alcaraz; Kochia iranica Bornm., misappl.; Kochia scoparia subsp. culta (Voss) O. Bolòs & Vigo; Kochia scoparia (L.) Schrad. subsp. scoparia; Kochia scoparia var. subvillosa Moq.; Kochia scoparia f. trichophylla (Voss) Schinz & Thell.; Kochia trichophylla Voss

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.
