Field note. — Salazaria mexicana is an 

 erect intricately branched shrub, the indi- 

 viduals commonly somewhat scattered and 

 often associated with Atriplex conferti- 

 folia. Cassia armata, Larrea tridontata, 

 Franscria dumosa, Krameria parvifolia 

 and Lj'cium andersonii. Occasionally, as 

 in the New York Mountains, it forms dense 

 colonies four feet high and ten feet broad. 

 The flowering branches at the top of the 

 shrub die the following winter and become 

 indurated and spiny. Next season the new 

 flowering branches are developed mostly 

 below the spiny fringe of old growth.
