PROLIFERATIONS. 



Proliferations Vivipary Prolepsis Lammas shoots 

 Dormant buds Epicormic shoots Adventitious buds 

 Apospory and apogamy. 



Proliferation consists in the unexpected and 

 abnormal on-growing or budding out of parts 

 stems, tubers, flowers, fruits, etc. which in the 

 ordinary course of events would have ceased to 

 grow further or to bear buds or leaf-tufts directly. 

 Thus we do not expect a Strawberry the swollen 

 floral axis to bear a tuft of leaves terminally 

 above the achenes, but it occasionally does so, and 

 similarly Pears may be found with a terminal 

 tuft of leaves, Roses with the centre growing out as 

 a shoot, Plantains {Planlago) with panicles in 

 place of simple spikes, and so on. 



We regard such cases as teratological, because 

 they are exceptional for the particular species, and 

 as pathological because they appear to be con- 

 nected with over-feeding in soils with excessive
