Polymorphic

I refer to those genera which have sometimes been called "protean" or "polymorphic," in which the species present an inordinate amount of variation; and hardly two naturalists can agree which forms to rank as species and which as varieties.

1897, Grant Allen, An African Millionaire Dr. Beddersley came -- a dapper little man, with pent-house eyebrows, and keen, small eyes, whom I suspected at sight of being Colonel Clay himself in another of his clever polymorphic embodiments.

Polymorphic redefinition in C++ is achieved by the use of virtual functions.

A polymorphic call looks like a procedural call, but where a procedural call has only one possible target subroutine, a polymorphic call can result in the execution of one of several different subroutines.

The fact that polymorphic equilibrium is not a dynamic equilibrium is significant with respect to the random distribution of velocity of temperature agitation among the molecules.
