is not brought into play until the rudiments of the
flower are already formed, whereas in the other the influence is exerted
prior to the formation of the flower. So that while the formation of
leaf-buds in place of flower-buds may be and generally is due to an
excess of nutrition, inducing over activity of the vegetative organs,
the production of phyllomorphic or chloranthic flowers may be owing
rather to a perversion of development arising from injury or from some
debilitating agency. The discrepancies in the assigned causes for the
conditions above mentioned may, therefore, in great measure, be
attributed to the different periods at which the causes in question
operate.
