CHENOPODIACEAE (GOOSEFOOT FAMILY) 367 



sinuate or entire ; flowers somewhat densely paniculate-spiked ; seed with obtuse 

 edges. Sparingly in waste places. (Adv. from Eu'.) 



6. C. rubrum L. (COAST BLITE.) Stem angled, much branched ; leaves 

 thickish, triangular-lanceolate, tapering below into a wedge-shaped base and 

 above into a slender point, sparingly and coarsely toothed, the upper linear- 

 lanceolate ; clusters scattered in axillary leafy spikes; calyx-lobes 2-4, rather 

 fleshy; stamens 1-2 ; seed shining, 1 mm. broad, the margin acute. Salt marshes, 

 Nfd. to N. J., and in saline places to Minn, and the Pacific coast. (Eu.) 



7. C. humile Hook. Similar, dwarf ; leaves lanceolate or spatulate, occasion- 

 ally hastate ; flowers in axillary glomerules ; seed 0.5 mm. broad. Brackish or 

 saline soil, coast of Me. (Miss Furbish); Man. to the Pacific. 



8. C. GLAUCUML. (OAK-LKAVEDG.) Low, spreading, glaucous-mealy ; leaves 

 sinuately pinnatijid-toothed, oblong, pale green above, white beneath; clusters 

 in axillary spikes, small ; seed sharp-edged. Waste places. (Nat. from Eu.) 



9. C. hybridum L. (MAPLE-LEAVED G.) Bright green throughout; stem 

 widely much branched (6-12 dm. high); leaves thin (5-15 cm. long), somewhat 

 triangular and heart-shaped, taper-pointed, sinuate-angled, the angles extending 

 into a few large and pointed teeth; racemes diffusely and loosely panicled, 

 leafless; calyx not fully covering the fruit, its lobes keeled. Woods; also 

 frequent in waste places and about cities, centr. Me. , westw. and south w. 



10. C. VULVARIA L. Low and spreading, branched from the base ; leaves 

 entire, broadly ovate, acutish (1 cm. long), on slender petioles nearly their own 

 length, very fetid when rubbed or crushed; inflorescences small, scattered. 

 Waste places, chiefly about cities. (Adv. from Eu.) 



11. C. ALBUM L. (LAMB'S QUARTERS, PIGWEED.) Erect, more or less 

 mealy ; leaves varying from rhombic-ovate to lanceolate or the uppermost even 

 linear, acute, all or only the lower more or less angulatc-toothed ; clusters 

 spiked-panicled, mostly dense ; calyx (2-2.7 mm. broad) with strongly carinate 

 lobes, nearly or quite covering the seed. Introduced everywhere. (Nat. from 

 Eu.) Var. vfRiDE (L.) Moq. is less mealy and has a less dense inflorescence. 

 Frequent, especially eastw. 



12. C. BerlandiSri Moq. Slender, 3-6 dm. tall ; leaves rhombic and somewhat 

 hastately l-several-toothed upon each side ; the upper leaves elliptical, entire, 

 mucronate ; inflorescence a loose pyramidal panicle; flowers smaller and less 

 glomerate than in C. album. Ottawa, Ont. (Macoun) to Fla. and Mex. A 

 doubtful species, perhaps only a variety of the preceding. 



13. C. MURA.LE L. Resembles the preceding, but less erect, loosely branched 

 (3-6 dm. high); leaves rhombic-ovate, acute, coarsely, sharply, and unequally 

 toothed, thin, bright green ; spikes or racemes diverging, somewhat corymbed ; 

 calyx-lobes scarcely keeled ; seed sharp-edged. Waste places. (Adv. from Eu.) 



14. C. URBICUM L. leather pale or dull green, nearly destitute of mealiness, 

 with erect branches (3-9 dm. high); leaves triangular, acute, coarsely and 

 sharply many -toothed ; spikes erect, crowded in a long and narrow racemose 

 panicle;- calyx-lobes not keeled; seed with rounded margins. Apparently 

 throughout our range. (Nat. from Eu.) 



15. C. POLYSFKRMUM L. Low, often spreading, green and wholly destitute 

 of mealiness ; leaves all entire, oblong or ovate and on slender petioles ; flowers 

 very small, in slender panicles in all the axils, the thin lobes of the calyx very 

 incompletely inclosing the fruit; seed obtuse-edged. Sparingly naturalized in 

 the Eastern States. (Adv. from Eu.) 



16. C. Boscianum Moq. Erect, slender (6-9 dm. high), loosely branched, 

 often nearly glabrous; leaves oblong- to linear-lanceolate (3-5 cm. long), 

 attenuate into a slender petiole, acute, the lower sinuate-dentate or often all 

 entire : flowers small, solitary or in small clusters upon the slender branchlets ; 

 calyx not strongly carinate. Ct. (Bissell) to the Great Lakes, s. to N. C. 

 and Tex. 



17. C. leptophyllum Nutt. Densely mealy or sometimes nearly glabrous (2-7 

 dm. high), simple or branched, often strict; leaves linear (1.5-2.5 cm. long), 

 entire, rather shortly petioled ; flowers closely clustered, in dense or interrupted 

 spikelets ; calyx-lobes strongly carinate. (C. album, var. Moq.) Near the
