A Peculiar Monstrosity in the Seedling of Zea Mays. 



By D. M. Mottier. 



(Abstract.) 



A seedling of Zea Mays Avas exhibited, which consisted of two per- 

 fectly deA'eloped shoots about eight centimeters long and two primary 

 roots. Each primary root bore several secondary roots, and secondary 

 roots had also put in an appearance at the loAver nodes of each slioot. 

 The double membei's arose just above and below the first node of the 

 embryo, and apparently by the resjiective bifurcation of the shoot and 

 in-imary root.
