 The Hatchet cactus is a little gem 

 from Mexico, so-called trom the shape 

 of the tubercles. It bloomed in San 

 Diegro on May day, scarce V^ inch in 

 length and breadth, with thirteen 

 bright magenta colored petals and 

 seven or eight pale lavendar sepals, 

 the four stigmata white, style and fi a-

 earlier days they were literally wo.-th 

 their weight in gold. The flowers are 

 open onlv in sunlight.
