CHENOPODIACEAE (GOOSEFOOT FAMILY) 



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

 N. Mex., and westw. Var. OBLONGIIOLIUM Wats, is a form with somewhat 

 broader oblong or oblong-lanceolate leaves. S. Me. (Parlin) ; Mo. (Bush), 

 and south westw. 



5. ATRIPLEX [Tourn.] L. ORACH 



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, drpd^a^.) 



1. A. ROSEA 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.) 



2. A. patula 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 <>r toothed, 

 often muricate on the back, united to near the middle. Nfd. to N. J., Mo., and 

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

 Gray. Erect or spreading, stout, at least the lower leaves l>r<><i<Uij triiuigular- 

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

 west w., chiefly in saline places and along the Great Lakes. (Eu.) Var. MTTO- 

 R\LIS (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. arenaria Nutt. Silvery-mealy, diffusely spreading ; leaves obl<i(/, nar- 

 rowed at base, n,',irly wnsi'le ; fruitiuy bracts broadly wedye-sluiped, united, 

 3-nerved, 2-5-toothed at the summit, and usually strongly muricate and reticu- 

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



4. A. arg6ntea 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. MON6LEPIS 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 /j.6vos, one, 

 ami XCTT^S, scale.) 



1. M. Nuttalliana (11. & S.) Wats. Branched from the base, 0.7-:', dm. 

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

 narrow, slender-petit >led, 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. CORISPERMUM [A. Jiiss.] L. BUG-SEED 



Calyx of a single delicate sepal on the inner side. Stamens 1 or 2, rarely 5. 

 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
