THE AMERICAN NATURALIST [Vol. XLII 



vulgare (Chrysanthemum leucanthemum), of which the 

 stems had been cut, bore heads on which at least a part 

 of the ligulate flowers had been changed to tubular flow- 

 ers, as well as heads, which in the axils of the bracts, bore 

 secondary ligulate florets. Life 27 mentions the case, of a 

 plant of Ambrosia art emisice folia which, having been run 

 over by a wagon and badly injured in consequence, bore 

 both staminate and pi still ate flowers in an abnormal con- 

 dition. A hedge composed of plants of Cereus margi- 



natum, which, under the name Organo, is largely used as a 

 hedge plant in Mexico, which was partly injured, prob- 

 ably because of securing cuttings for planting, shows 

 numerous fasciations. 28 Klebs 29 mentions the observa- 

 tions of Krasan, who noted fasciation caused by a loss of 

 leaves through the action of june bugs or spring frosts.
