GOOSEFOOT FAMILY 71 



6. Chenopodium Fremontii S. Wats. Fremont's Goosefoot. Fig. 1487. 



Chenopodium Fremontii S. Wats. Bot. King Expl. 287. 1871. 

 Botrys Fremontii Lunell, Amer. Midi. Nat. 4: 305. 1916. 



Annual with pale green and more or less mealy herbage especially on the lower leaf- 

 surfaces, the upper surfaces and the stems often glabrous ; stems erect, simple below, branched 

 above, slender, 3-8 dm. high. Leaves broadly triangular and usually hastate, 15-40 mm. long, 

 obtuse at the apex, truncate or somewhat cuneate at base, usually with rounded or acutish basal 

 lobes, those of the inflorescence smaller and entire; petioles slender, often nearly as long as the 

 blade ; flower glomerules small, arranged in slender often interrupted paniculate spikes ; calyx- 

 lobes completely enclosing the fruit ; pericarp free ; seed horizontal, 1 mm. broad, the margin 

 obtuse. 



Dry slopes and flats, mainly Arid Transition Zone; central British Columbia, eastern Washington, and Ore- 

 gon, south through western Nevada to the San Bernardino Mountains, California, and eastward to North Dakota, 

 Texas, and northern Mexico. Type locality: on the North Platte River, Wyoming. June-Nov. 



7. Chenopodium glaucum L. Oak-leaved Goosefoot. Fig. 1488. 



Chenopodium glaucum L. Sp. PI. 220. 1753. 

 Blitum glaucum Koch, Syn. Fl. Germ. 608. 1837. 



Annual, succulent and glabrous, or nearly so, except the densely white-mealy undersurfaces 

 of the leaves; stems freely branching, decumbent or prostrate, 4-20 cm. long. Leaves usually 

 oblong, varying from lanceolate to narrowly ovate, 2-5 cm. long, sinuate-dentate, or the upper- 

 most sometimes entire, narrowed at base to a short petiole; flowers in short axillary often 

 branched spikes ; calyx-lobes narrowly oblong, thin, not keeled, concealing only a small portion 

 of the fruit; utricle dark brown; pericarp free; seed vertical in the lateral flowers, often 

 horizontal in the terminal, sharp-edged, 0.6 mm. broad. 



Moist sandy soils, Humid Transition Zone; banks of the Columbia River near Bingen, Washington, to the 

 vicinity of Portland. Naturalized from Europe. July-Oct. 



8. Chenopodium farinosum (S. Wats.) Standley. Coast Goosefoot. Fig. 1489. 



Chenopodium murale var. farinosum S. Wats. Proc. Amer. Acad. 9: 97. 1874. 



Chenopodium farinosum Standley, N. Amer. Fl. 21: 28. 1916. 



Chenopodium macrospermum subsp. halophilum f. farinosum Aellen, Rep. Spec. Nov. 26: 43. 1929. 



Annual, much branched from the base, the branches stout, succulent, erect or ascending, 

 1^1 dm. long, glabrous. Leaves rhombic to narrowly deltoid-rhombic, 2-5 cm. long, obtuse at 

 the apex, cuneate or rounded at base, irregularly sinuate-dentate or repand-dentate, 3-nerved 

 from the base, succulent, glabrous or nearly so above, densely farinose beneath, becoming 

 glabrate in age ; glomerules in dense spikes, arranged in the axils of the upper leaves forming 

 dense leafy panicles; calyx-lobes rounded, not carinate, nearly enclosing the utricle; seed vertical, 

 dark reddish brown, 1 mm. long, the margin obtuse. 



Moist ground near the coast, Upper Sonoran Zone; San Francisco to Los Angeles County, California. Type 

 locality: San Francisco. July-Oct. 



It is possible but hardly likely that this species, as proposed by Aellen, is to be considered conspecific with 

 the South American C. macrospermum Hook. f. which was originally described from plants collected on the 

 Falkland Islands. 



9. Chenopodium rubrum L. Red Goosefoot. Fig. 1490. 



Chenopodium rubrum L. Sp. PI. 218. 1753. 



Blitum rubrum Reichb. Fl. Germ. Excurs. 582. 1832. 



Botrys rubra Lunell, Amer. Midi. Nat. 4: 306. 1916. 



Glabrous more or less succulent annual, the stems erect, simple or more or less branched, 

 often reddish. Leaves rhombic-ovate to rhombic-lanceolate, 2.5-15 cm. long, coarsely sinuate- 

 dentate, often hastate ; petioles slender, equaling or shorter than the blades ; glomerules in dense 

 spikes, sessile in the axils of the reduced and often entire upper leaves ; calyx-lobes 3 or 5, red- 

 dish, not carinate, broadly obovate or ovate; utricle slightly exceeding the calyx-lobes, green; 

 seeds vertical, or a few sometimes horizontal in the same inflorescence, strongly compressed, 

 brown, 0.8-1 mm. long. 



Moist saline soils, Transition and Boreal Zones; British Columbia to northern California, and eastward 

 across the continent; also in Europe and Asia. July-Oct. 



Chenopodium humile Hook. Fl. Amer. 2: 127. 1838. (C. rubrum var. humile S. Wats.) Branched from 

 the base, with prostrate or ascending branches 1-2 dm. high. Leaves mostly hastate-lobed, otherwise entire to 

 sinuate-dentate; glomerules solitary in the leaf axils or subspicate above; seeds 0.5-0.6 mm. broad. Closely 

 related to C. rubrum and possibly belonging to the same specific complex. British Columbia to northern Cali- 

 fornia, Manitoba, and Colorado; also on the coast of Maine and in Europe. 



10. Chenopodium capitatum (L.) Aschers. Strawberry Blite. Fig. 1491. 



Blitum capitatum L. Sp. PI. 2. 1753. 



Chenopodium capitatum Aschers. Fl. Brand. 572. 1864. 



Bright green glabrous annual, the stems erect with ascending branches, 2-6 din. high. Lower 

 leaves triangular, 4-10 cm. long, usually hastate, and more or less irregularly sinuate-dentate, 

 their petioles slender and usually exceeding the blades ; upper leaves reduced, narrower, shorter-
