From the above data we may conclude : 



(1) That the production of individuals by bud propagation 

 on the leaves of Dioiuea and Drosera occasionally occurs. 



(2) That the condition described above in Dioniea is a case 

 of non-sexual reproduction supplanting the ordinary sexual 

 process. 



(3) That the bud axis may be considerably elongated, and 

 provided with evident roots and leaves previous to separation 

 from the parent axis.
