20 BULLETIN 1345, U. S. DEPARTMENT OF AGRICULTURE 
Department sample 7219 (W), consisting of plants in full seed, 
cut just above the ground. before the leaves had begun to dry, on 
the Jornada Range “Reserve, some 45 miles northeast of Las Cruces, 
N. Mex., at an altitude of about 4,300 feet, October 14, 1914, con- 
tained, on an air-dry basis, 4.2 per cent of moisture, and, on a 
water-free basis, 13.4 per cent of ash, 2.2 per cent of ether extract, 
27.9 per cent of crude fiber, 43 per ‘cent of nitrogen-free extract, 
13.5 per cent of protein, and 16.5 per cent of pentosans. 
Cattle eat the plant freely, along with other similar species that 
grow with it, especially after it is mature and covered with seed. 
CHENOPODIUM INCANUM (S. Wats.) Heller 
Chenopodium incanum is an ash-gray annual herb of spreading 
habit, sometimes 18 inches high, but ‘usually lower. It has the 
general mealiness common to “the genus, developed to a greater 
degree than in most other species, Which gives the peculiar gray 
color. When young and growing vigorously, the broadly triangular 
leaves are rather thick and have a cool or clammy feel. 
This plant grows freely on the dry plains and hillsides of the 
semiarid Southwest, from western Nebraska, Kansas, and Texas, 
westward to Utah, New Mexico, and Arizona, southward into 
northern Mexico. It requires s less water than the other species of 
this genus so far mentioned, and will also endure relatively large 
quantities of alkali in the soil. 
Department sample 7198 (W), consisting of plants in flower, cut 
just above the ground, on th: Jornada Range Reserve, about 35 
miles north of Las Cruces, N. Mex., at an elevation of about 4,100 
feet, May 31, 1914, contained, on an air-dry basis, 3.8 per cent of 
moisture, and, on a water-free basis, 27.4 per cent of ash, 1.8 per 
cent of ether extract, 16.9 per cent of crude fiber, 32.8 per cent of 
nitrogen-free extract, 21.1 per cent of protein, and 12.3 per cent of 
pentosans. 
Cattle and sheep eat it freely, along with the grasses and other 
herbage common where it grows. <As a species adapted to places in 
which many other forage plants are at a disadvantage, this species 
is important. 
CHENOPODIUM PRATERICOLA Rydb. 
Vhenopodium pratericola (Pl. VII, fig. 1) is an annual, with 
greenish, mostly erect stems that turn reddish in the fall. Its leaves 
are undivided, 1 to 2 inches long, and a fourth as wide. It is only 
slightly mealy on the younger parts. It produces an abundance of 
seeds. 
This is one of the several closely-related species of goosefoot that 
are widely distributed in the Western States, from Saskatchewan to 
northern Mexico, and from the Pacific eastward to Missouri. It 
grows in dry or sandy soils, or in the cultivated areas as a waste- 
eround or fence-corner weed. It rarely if ever forms a complete 
stand over any large area, but grows under the protection of low 
shrubs. 
Both department samples consist of plants in full leaf, with ripe 
seeds. Sample 7207 (W) was collected on the sagebrush land, 
above irrigation level, at an elevation of about 6,200 feet, at Craig,
