368 CHBNOPODIACEAE (hOOSEH-OOT FAMIL-^) 



coast, Me. to N. J. and Pa.; n. shore of L. Erie; and from w. Wise, to Col., 

 N. Mex., and westw. Var. oblongif6lium Wats, is a form witli somewhat 

 broader oblong or oblong-lanceolate leaves. — S. Me. {Parlin); Mo. (_Bush), 

 and southwestw. 



6. AtRIPLEX [Tourn.] L. Obach 



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 inclosed 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 Orach, 

 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 and with spiked-clustered flowers ; in summer and 

 autumn. (The ancient Latin name, a corruption of the Greek, dT^i£0a|is.) 



1. A. r6sea. L. Hoary-mealy; leaves short-petioled or the upper sessile,- 

 rhombic-ovate or oblong with a wedge-shaped base, coarsely sinuate-toothed; 

 fertile flower.s mostly clustered in the axils ; fruiting bracts broad, often cut- 

 toothed and warty. — Sparingly introduced at the East. (Adv. from Eu.) 



2. A. pitula L. Erect or prostrate (3-12 dm. high), glabrous or somewhat 

 scurfy ; leaves narrowly lanceolate-hastate (2-10 cm. 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 murioate on the back, united to near the middle. — Nfd. to N. J., Mo., and 

 B.C. (Eu.) Very variable; the marked extremes are: Var. hastXta (L.) 

 Gray. Erect or spreading, stout, at least the lower leaves broadly triangular- 

 hastate, often coarsely and irregularly toothed. — Nfd. to Va., Mo., and north- 

 westw., chiefly in saline places and along the Great Lakes. (Eu.) Var. litto- 

 rXxis (L.) "Gray. Slender ; leaves linear-lanceolate to linear, rarely subhastate 

 or toothed. ^P. E. I. to N. J., and westw. along the Great Lakes. 



3. A. arenHria Nutt. Silvery-mealy, diffusely spreading ; leaves oblong, nar- 

 rowed at base, nearly sessile; fruiting bracts broadly wedge-shaped, united, 

 3-nerved, 2-b-toothed at the summit, and usually strongly muricate and reticu- 

 late on the sides. — Sandy beaches, along the coast, Mass. to Fla. 



4. A. argfintea Nutt. Usually low, much branched, gray-scurfy, leafy ; leaves 

 deltoid or subrhombic, often subhastate ; staminate flowers in terminal spikes ; 

 fruiting bracts round-rhombic, indurated, united, the free margins more or less 

 dilated and deeply toothed, the sides variously appendaged. — Red River Valley, 

 Minn., southw. and westw. 



6. M0N6lEPIS Schrad. 



Flowers small, .glomerate in the upper axils. Sepal 1, green, entire, bract- 

 like, fleshy, obtuse. Utricle moderately flattened. Seed vertical, much com- 

 pressed. Embryo annular about copious albumen. (Name from fidvos, one, 

 and Xeirfs, scale.) 



1. M. NuttalliSlna (R. & S.) Wats. Branched from the base, 0.7-3 dm. 

 high, somewhat fleshy, rather pale green, scarcely or not at all mealy ; leaves 

 narrow, slender-petioled, hastate, passing gradually into foliaceous bracts. — 

 Saline and alkaline soil, from the Great Plains westw., extending east to Man., 

 and Minn. ; and introd, in Mo. 



7. CORISPtRMUM [A. Jnss.] L. Bdg-sebd 



Calyx of a single delicate sepal on the inner side. Stamens 1 or 2, rarely 6. 

 Styles 2. Fruit oval, flat, with the outer face rather convex and the inner con- 

 cave, sharp-margined, seed vertical. Embryo slender, coiled around a central 

 albumen. — Low branching annuals, with narrow linear alternate 1-nerved
