A. semibaccata is for the most’ part a cultivated crop wherever it 
is of any importance, so that it can not be classed among the native 
forage plants. Reports from Australia credit the quality of the wool 
produced there in part to the saltbush eaten by the sheep. 
ATRIPLEX THORNBERI (Jones) Standl. 
Atriplex thornberi is a low, branching ‘annual, similar in most 
respects to A. elegans and A. fasciculata, “and growing in much the 
same area. This species is known as yet only from the low, hot, 
and dry plains of southern Arizona, although it probably extends 
into southern California and northern Mexico. 
Department sample 8572 (G), consisting of mature fruiting plants, 
from which the seed had begun to fall, collected at Phenix, Ariza 
September 24, 1906, contained, on an air-dry basis, 1.4 per cent of 
moisture, and, on a water-free basis, 17.8 per cent of ash, 2.2 per 
cent of ether extract, 22.6 per cent of crude fiber, 46.2 _per cent of 
nitrogen-free extract, 11.2 per cent of protein, and 17.3 per cent 
of pentosans. 
A. thornberi is one of the annuals which doubtless could be used 
most seasons to obtain a crop of usable forage from land that other- 
wise would produce nothing. 
ATRIPLEX TRIDENTATA Kuntze * 
Atriplex tridentata is a low perennial, very similar in general 
appearance to Nuttall’s saltbush or the saltsage of the Red “Desert 
region of south-central Wyoming. It is usually a little larger, being 
10 inches to 2 feet high, with longer and narrower leaves, and 
geverally not so yellowish, looking almost white when young, from 
the thick, white, scurfy covering on leaves and stems. The leaves 
are longer (often 2 inches) and mostly narrower, sometimes not 
more than one-sixteenth of an inch wide, and the bracts of the 
abundant fruit are different. Otherwise it resembles the saltsage 
and goes without distinction under that name in Wyoming. 
It is known only from the plains of southern Wyoming, north- 
western Colorado, and northeastern Utah. 
Department sample 7220 (W), consisting of the growth of a year, 
with the stems in full leaf and nearly mature fruit, collected at. 
Rawlins, Wyo., August 17, 1914, contained, on an air-dry basis, 4.4 
per cent of moisture, and, on a water-free basis, 21.9 per cent of
