§ 4. Annual, not mealy, but more or less glandular-pubescent, aromatic; calyx 2–3-parted, dry in fruit; seed often vertical; embryo not a complete ring.
C. Bòtrys, L. (Jerusalem Oak. Feather Geranium.) Glandular-pubescent and viscid; leaves slender-petioled, oblong, obtuse, sinuate-pinnatifid; racemes cymose-diverging, loose, leafless; fruit not perfectly enclosed.—Widely introduced. (Nat. from Eu.)
C. ambrosioìdes, L. (Mexican Tea.) Smoothish; leaves slightly petioled, oblong or lanceolate, repand-toothed or nearly entire, the upper tapering to both ends; spikes densely flowered, leafy, or intermixed with leaves; fruit perfectly enclosed in the calyx.—Waste places, common throughout our range, especially southward. (Nat. from Trop. Amer.)
Var. anthelmínticum, Gray. (Wormseld.) Leaves more strongly toothed, the lower sometimes almost laciniate-pinnatifid; spikes more elongated, mostly leafless.—From Long Island and southward, west to Wisc. and Tex. (Nat. from Trop. Amer.)
4. ROUBIÈVA, Moquin.
Flowers minute, perfect or pistillate, solitary or 2–3 together in the axils. Calyx urceolate, 3–5-toothed, becoming enlarged and saccate, contracted at the apex and enclosing the fruit. Stamens 5, included; styles 3, exserted. Fruit membranaceous, compressed, glandular-dotted. Seed vertical. Embryo annular.—Perennial glandular herb, with alternate pinnatifid leaves.
R. multífida, Moq. Prostrate or ascending, branching and leafy; leaves lanceolate to linear (½–1½´ long), deeply pinnatifid with narrow lobes; fruiting calyx obovate. (Chenopodium multifidum, L.)—Sparingly introduced in the Atlantic States. (Adv. from S. Amer.)
5. ÁTRIPLEX, Tourn. Orache.
Flowers monœcious or diœcious; the staminate like the flowers of Chenopodium, but sterile by the abortion of the pistil; the fertile consisting simply of a naked pistil enclosed between a pair of appressed foliaceous bracts, which are enlarged in fruit, and sometimes united. Seed vertical. Embryo coiled into a ring around the albumen. In one section, including the Garden Orache, there are some fertile flowers with a calyx, like the staminate, but without stamens, and with horizontal seeds.—Herbs (ours annuals) usually mealy or scurfy with bran-like scales, with spiked-clustered flowers; in summer and autumn. (The ancient Latin name, a corruption of the Greek, ἀτράφαξις.)
A. ròseum, L. Hoary-mealy; leaves short-petioled or the upper sessile, rhombic-ovate or oblong with a wedge-shaped base, coarsely sinuate-toothed; fertile flowers mostly clustered in the axils; fruiting bracts broad, often cut-toothed and warty.—Sparingly introduced at the east. (Adv. from Eu.)
