nHeterauxesis(Bot) Unequal growth of a cell, or of a part of a plant.
Century Dictionary and Cyclopedia
nheterauxesisIn botany, irregular or unsymmetrical growth. It is a condition observed in the apex of growing organs of plants, superinduced by certain irregularities in the conditions upon which growth depends, such as variations in the osmotic properties of the cell-sap, in the physical properties of the primordial utricle, or in those of the cell-wall itself, giving rise to inequalities in the rate of growth of different parts of the organ, which in turn changes the direction of its growth.
