Shrub, 4 to 10 dm. high, the numerous branchlets leafy: 

 herbage minutely pubescent on all but the older parts, the foliage 

 sometimes resinous-punctate: principal leaves flat, linear, acute, 

 .5 to 2 cm. long, especially the lower commonly with minute fas- 

 cicled ones in their axils : inflorescence cymose ; the cymes round- 

 topped, terminating the branchlets : involucre narrowly campanu- 

 late, 4 or 5 mm. high ; bracts loosely imbricated, chartaceous with 

 dull-green midrib, rather obtuse but the small outer ones often 

 acute : rays one or two or entirely lacking in some heads, occa- 

 sional plants with all the heads discoid : disk-flowers 5 to 8 : 

 style-appendages flat, ovate or narrower, acute : achenes white- 

 villous. 



Upper portion of the Lower Sonoran Zone: Mohave Desert 

 from the Providence Mts. on the east to Tejon Pass on the west, 

 north to Owens Valley and south through Cajon Pass as far as 

 West Riverside; also in Rubio Canon, back of Los Angeles, ace. 

 to McClatchie. 8 Most plentiful from the Mohave River westward 

 through Antelope Valley. Apr.-Jun. Perhaps not distinct from 

 E. larici folia of Arizona, etc., but that has narrower more acute 

 bracts and more slender style-appendages.
