CHKNOPODIACE^E. (GOOSKFOOT FAMILY.) 433 



clusters simple (large), interruptedly spliced, the upper leafless; stamens 1-5; 

 cali/x berry-like in fruit ; seed ovoid, flattish, smooth, with a very narrow 

 margin. (Blitum capitatum, L.) Dry rich ground, along the Great Lakes, 

 northward and westward. The calyx becomes pulpy and bright red in fruit, 

 when the large clusters look like strawberries. (Eu.) 



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. B6TRVS, L. (JERUSALEM OAK. FEATHER GERANIUM.) Glandular- 

 pubescent and viscid ; leaves s/ender-pet/oled, oblong, obtuse, sinuate-pinnat- 

 itid ; racemes ct/mose-dieerginrj, loose, leafless; fruit not perfectly enclosed. 

 Widely introduced. (Nat. from Eu.) 



C. AMBROSIOIUES, L. (MEXICAN TEA.) Smoothish ; leaves slightly peti- 

 oled, oblong or lanceolate, repand-toothed or nearly entire, the upper tapering 

 to both ends; spikes densely flowered, leafy, 01 intermixed with leaves; fruit 

 perfectly enclosed in the calyx. Waste places, common throughout our 

 range, especially southward. (Nat. from Trop. Amer.) 



Var. AXTHELMINTICUM, Gray. (WORMSEED.) Leaves more strongly 

 toothed, the lower sometimes almost laciniate-pinnatitid ; spikes more elon- 

 gated, mostly leafless. From Long Island and southward, west to Wise, and 

 Tex. (Nat. from Trop. Amer.) 



4. ROUBIEVA, 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 membrauaceous, compressed, glandular-dotted. Seed vertical. Embryo 

 annular. Perennial glandular herb, with alternate pinnatifid leaves. 



K,. MiTLTfriDA, Moq. Prostrate or ascending, branching and leafy; leaves 

 lanceolate to linear (-J - 1|' long), deeply pinnatifid with narrow lobes ; fruiting 

 calyx obovate. (Chenopodium multifidum, L.) Sparingly introduced in the 

 Atlantic States. (Adv. from S. Amer.) 



5. ATRIPLEX, Tourn. ORACHE. 



Flowers monoecious or dioecious; the staminate like the flowers of Cheno- 

 podium, 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, oTpd</>a|js.) 



A. R^SEUM, 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.) 



1. A. patulum, L. Erect or prostrate (1-4 high), dark green and 

 glabrous or somewhat scurfy ; leaves narrowly lanceolate-hastate (1 -4' long), 

 the lower sometimes opposite, entire or sparingly sinuate-dentate, petioled, 

 the upper lanceolate to linear ; flowers clustered in rather slender spikes, the 

 two kinds together or separate ; fruiting bracts ovate-triangular or rhombic- 

 hastate, entire or toothed, often muricate on the back, united to near the
