ECHINOCACTUS POLYANCISTRUS EB 

 The Hermit cactus, so-called because 

 It is rare to find more than one in a 

 place, is a strikingly beautiful cactus 

 which I have sen only on the Mohave 

 desert in its wild state. The largest 

 plant I have seen is 18 ijiches high and 

 4 inches in diameter; each tubercle 

 bears three to seven hooked, round, 

 brownish-pink spines, with which are 

 interspersed fewer ivory white spines, 

 not hooked, very pleasing in contrast. 

 Flower over 2 inches long, of equal 

 width, petals bright magenta, green at 

 base, filaments and stigmata green, 

 anthers white. They were once cata- 

 logued at $15 apiece, and are still rare 

 in 'collections, unfortunately seldom 

 long surviving transplanting from 

 their native sands. Too much mois- 

 ture soon proves fatal.
