1. Atriplex patula L. Spreading Orache. (Fig. 1378.) 
33 ; Atriplex patula I,. Sp. Pl. 1053. 1753. 
Alriplex littoralis I. Sp. Pl. 1054. 1753. 
Annual, dark green, glabrous or somewhat scurfy 
above; stem much branched, diffuse, ascending or 
sometimes erect, 1°-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, 1/-5’ long, 2’/-1%4’ 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 
gi y also of Asia. Much less common than the following 
Ff sey aa species. July-Aug. 
2. Atriplex hastata L. MHalberd-leaved Orache. (Fig. 1379.) 
Alriplex hastata I. Sp. Pl. 1053. 1753. 
A. patulum var. hastatum A.Gray, Man. Ed.5, 409. 1867. 
Alriplex 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, 1°-214° tall. Leaves slender-petioled, 
acuminate, the lower broadly triangular-hastate, 
seldom more than twice as long as wide, entire or 
sparingly toothed, 1/—4’ 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 I, Red Orache. 
(Fig. 1380. ) 
Atriplex rosea ¥,, Sp. Pl. Ed. 2, 1493. 1763. 
Annual, pale green and very scurfy, stem erect or de- 
cumbent, usually much branched, 1°-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, 3/-314’ 
long, '4’-314’ 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 New 
York and New Jersey. Adventive from Europe. Aug.—Oct.
