16 NORTH AMERICAN FLORA [VoLumME 21 
12. Chenopodium hians Standley, sp. nov. 
Ill-scented erect annual, 4-8 dm. high, usually simple at the base, or with a few short 
slender weak branches, sparsely branched above, the branches stout, erect or nearly so, copi- 
ously and coarsely farinose, obscurely and obtusely angled; petioles stout, half as long as the 
blades or shorter; leaf-blades elliptic-oblong, oblong, or narrowly lance-oblong, 1.2-3 em. long, 
3-8 mm. wide, rounded or obttse at the apex, very shortly apiculate, cuneate at the base, 
green and glabrate on the upper surface, densely and rather coarsely white-farinose beneath, 
thick, the upper blades sometimes linear; glomerules large, in very stout, dense, erect, axillary 
or narrowly paniculate spikes; calyx densely farinose, cleft nearly to the base, the lobes rounded- 
oblong or ovate, obtusely carinate, yellowish, tinged with green, erect at maturity and exposing 
the fruit; pericarp closely adherent; seed horizontal, 0.8-1 mm. broad, black, shining, nearly 
smooth, the margin obtuse. 
Type collected near Dulce, New Mexico, altitude 2150 meters, August 19, 1911, Paul C. Standley 
8129 (U.S. Nat. Herb. no. 687056 ). 
DIsTRIBUTION: Dry hillsides, southwestern Wyoming and northern New Mexico. 
V. Cycloidia. Plants farinose with whitish inflated trichomes. Leaves short-petiolate, 
the blades linear, entire. Calyx-lobes rounded on the back, slightly accrescent and rotate 
in fruit. Pericarp adherent to the seed, red. Seed horizontal. 
13. Chenopodium cycloides A. Nelson, Bot. Gaz. 34: 363. 1902. 
Erect annual, 3-4 dm. high, much branched, the branches slender, ascending, usually 
from a spreading base, mostly simple, glabrous or very sparsely and finely farinose, usually 
reddish; petioles 3 mm. long or less; leaf-blades linear, 1-1.5 cm. long, I-1.5 mm. wide, 1- 
nerved, obtuse or acutish, thick, bright-green, glabrous on the upper surface, minutely and 
sparsely farinose beneath; flowers in rather large glomerules, these in slender or stout, short, 
dense or interrupted, narrowly paniculate spikes, the inflorescence nearly naked; calyx sparsely 
farinose, shallowly lobed, the lobes broadly rounded at the apex, rounded on the back, the 
margins scarious, the whole calyx broadly spreading and slightly accrescent in fruit; pericarp 
adherent, bright-red, minutely tuberculate; seed horizontal, strongly compressed, 1.3 mm. 
broad, nearly smooth, black, shining, the margin acutish. 
TyPE LocaLity: Grant County, Kansas. : 
DIstTRIBUTION: On sandhills, southwestern Kansas and southern New Mexico. 
VI. Bosciana. Plants bright-green and glabrate or copiously farinose with whitish in- 
flated trichomes. Leaves long-petiolate, the blades broadly oblong to rhombic, or the upper- 
most narrower, entire or subhastate, the lowest sometimes sinuate-dentate. Glomerules 
of flowers spicate or cymose. Calyx-lobes carinate, usually completely enclosing the fruit. 
Pericarp free from or adherent to the seed. Seed horizontal. 
14. Chenopodium carnosulum Mog. in DC. Prodr. 13?: 64. 1849. 
Erect or ascending annual, much branched, the branches slender, spreading, striate, 
1-3 dm. long, sparsely farinose when young, glabrate in age; petioles 1-2 mm. long; leaf-blades 
rhombic-deltoid to ovate-oblong or elliptic, 4-8 mm. long, 2-4 mm. wide, obtuse or acutish, 
cuneate to rounded at the base, thick and succulent, sparsely farinose when young but soon 
glabrate, entire or near the base very shallowly lobed, the lobes broadly rounded, the lateral 
veins obsolete; flowers in small axillary glomerules shorter than the leaves; calyx 5-lobed, the 
lobes rounded, farinose, succulent, subcarinate, imperfectly enclosing the fruit; pericarp ad- 
herent, thin, green; seed horizontal, 1 mm. broad, nearly black, the margin obtuse. 
Typr LOCALITY: Given as California, but this probably incorrect; possibly the type really 
came from Patagonia. 
DrsTRiBuTION: On Mt. Orizaba, Mexico; also in southern Argentina., 
15. Chenopodium nevadense Standley, sp. nov. 
Erect annual, 2.5-3 dm. high, much branched, the branches subdichotomous, ; “ascending, 
stout below, slender and flexuous above, bright-green, slightly striate; petioles rather stout,
