Peak on the Mohave Desert (Hall & Chandler, nos. 6856, 6873. 

 6941, 7092), and reappears on the Colorado Desert at Palm 

 Springs, where the receptacle is nearly or quite smooth (Parish. 

 nos. 4120,. 6088; Hall, no. 5760). This is perhaps the normal 

 form of the species, it being common and widely distributed. In 

 it the number of rays is normally 8.
