A simple characterization of well ordering?

A linear order with no infinite descending subsequences (i.e. infinite no subsequences of the form a_0 > a_1 > a_2 > ...)?

The simplest way to answer this, of course, is to crowdsource the net and seek out hits on the combined keywords "infinite descending" and "well order". This, of course, leads straight to the term "well-quasi-ordering" and everything else related to it.
