shape of the flower is much the same as that of E. umbellatum, 

 2 lines long, lobes oblong-oval, rounded, equal, outer three winged 

 on the midrib; anthers exserted, purple; flowers woolly within 

 at base. This probably belongs with the E. racemosum group, 

 but is unique. Dedicated to Miss Stokes of Salt Lake City who 

 has done much work on the genus. Pleasant Canyon, Panamint

Atriplex draconis n. sp. Annual, with the habit of A- 

 argentea and Amarantus albus, 1 to 2 feet high, much branched, 

 stems stout and thick, central one erect, lower lateral ones pros- 

 trate, whole plant forming rounded ovate tufts, slightly mealy; 

 leaves all alternate, on petioles from y z to as long as the blades> 

 about 2 inches long, ovate to triangular, cuneate at base, sharply 

 acute, palmately 3-nerved, moderately thin; fruit in dense clusters 

 in the axils of all the leaves, some flowers in fruit on slende 

 pedicels 6 to 8 lines long, and thickened above, others sessile in 

 the same cluster; bracts united nearly to the top, almost linear, 

 acute, not toothed, 3 to 4 lines long, at the base produced into 

 unequally laciniate lobes 1 to 2 lines long which also sometimes 

 have green ridges or teeth on their sides, this gives the fruit a 

 fantastic appearance, of halberd shape. Dioecious. Wadsworth

 wide; seeds in 2 rows, very broadly winged, 2 lines wide from edge
