Atriplex patula L. Sp. PI. 1053. 1/53. 

 Atriplex litloralis L. Sp. PI. 1054. 1753. 



Annual, dark green, glabrous or somewhat scurfy 

 above; stem much branched, diffuse, ascending or 

 sometimes erect, i-3 long. Leaves lanceolate or 

 linear-lanceolate, slender-petioled, or the uppermost 

 nearly sessile, entire, sparingly toothed, or 3-lobed 

 below the middle, acuminate at the apex, narrowed 

 or cuneate at the base, I'-s' long, 2 // -i^ / wide; 

 flowers in panicled interrupted slender mostly leaf- 

 less spikes, and usually also capitate in the upper 

 axils; fruiting bractlets united only at the base, 

 fleshy, triangular or rhombic, 3 / '-4 // wide, their sides 

 often tubercled; radicle of the embryo ascending. 



In waste places and ballast, Nova Scotia and Ontario 

 to southern New York and New Jersey. Naturalized 

 from Europe, or perhaps indigenous northward. Native 

 also of Asia. Much less common than the following 

 species. July-Aug. 



2. Atriplex hastata L,. Halberd-leaved Orache. (Fig. 1379.) 



Atriplex hastata L. Sp. PI. 1053. 1753. 

 A.patulum var. hastatum A. Gray, Man. Ed. 5, 409. 1867. 

 Atriplex patula var. subspicata S. Wats. Proc. Am. 

 Acad. 9: 107. 1874. 



Annual, pale green, or purple, somewhat scurfy, 

 at least when young; stem erect or ascending, 

 branched, i-2^ tall. Leaves slender-petioled, 

 acuminate, the lower broadly triangular-hastate, 

 seldom more than twice as long as wide, entire or 

 sparingly toothed, \ f -\ f long, truncate or narrowed 

 at the base, the basal lobes divergent, acute or acu- 

 minate; upper leaves sometimes triangular-lanceo- 

 late; inflorescence as in the preceding species; the 

 fruiting bractlets sometimes broader. 



In salt meadows and waste places mostly near the 

 coast, New Brunswick to South Carolina, and in saline 

 soil, Manitoba to British Columbia, Nebraska and 

 Utah. Also in Europe. The western plant is more 

 scurfy than the eastern. Aug. -Oct. 



3. Atriplex rosea L/. Red Orache. 



(Fig. 1380.) 

 Atriplex rosea L, Sp. PI. Ed. 2, 1493. 1763. 



Annual, pale green and very scurfy, stem erect or de- 

 cumbent, usually much branched, i-2^ high. Leaves 

 ovate or rhombic-ovate, short-petioled or the upper ses- 

 sile, coarsely sinuate-dentate, obtuse or acute at the 



apex, narrowed or subtruncate at the base, %' 

 long, ] f -?>yi. f wide, often turning red; flowers mostly 

 in axillary capitate clusters, often dense, or some in 

 few terminal spikes; fruiting bractlets broadly ovate or 

 triangular-hastate, strongly veined, mealy-white, dry, 

 about 3" broad, united only at their bases, their margins 

 toothed or lacerate and sides tubercled. 



In waste places and ballast, Nova Scotia to northern Ne\v 

 York and New Jersey. Adventive from Europe. Aug.-Oct.
