The sagebrush habitat, where it was studied three miles east of 

 Wallula, is not entirely homogeneous. The dominant plant is the 

 common sagebrush (Artemisia tridentata). Commonly mixed with 

 this are two species of rabbit brush (Chrysotkamnus viscidiflorus and 

 Chrysothamnus nauseosus graveolens). In places one or other of 

 these shrubs may be more abundant than the sagebrush. The hop sage 

 (Grayia spinosa) and the antelope brush (Kunzia tridentata} occur in 

 lesser abundance. In sandy areas a cactus (Opuntia polyacantha) is 

 often found. The wheat bunchgrass (Agropyron spicatum) is found 

 very sparingly, but under native conditions was evidently much more 

 abundant than at present. Where there has been extensive pasturage 

 and tramping by stock the yarrow (Achillea mille folium lanulosa) is 

 common.
