ECHINOCACTUS JOHNSONII Engelm, 



Johnson's hedghog cactus was named 

 for J. E. Johnson, an early Mormon 

 naturalist, who discovered it about S. 

 George in southern Utah. It is a 

 rare and handsome plant, 4 to 7 inches 

 high, oval, 3 to 5 inches in diameter, 

 densely covered with stout reddish- 

 gray spines — turning deep red when 

 wet. The flower is about 2V4 inches 

 broad, of a rose purple normally, but 

 some plants which opened their flowers 

 while packed in a box away from the 

 light leave light yellowish-green petals 

 marked with deep maroon at base. 

 Anthers pale primrose yellow; fiila- 

 ments y 2 inch lond, the inner ones; 

 white, outer ones reddish. Growing in 

 out-of-the-way desert places in Ne- 

 vada, Arizona, and California, it costs 

 much trouble to secure this beautiful 

 species.
