homogonous

Having all the flowers alike in terms of the stamens and pistils.

In Hottonia, a Primulaceous genus of two species, the European one has heterogonous dimorphism for cross-fertilization: the American one has homogonous showy flowers with only the general chance for intercrossing, and earlier flowers which are cleistogamous for self-fertilization.

Existing on a continuum; able to be transformed one into another by means of continuous change.

Time and an instant, space and a point, boundary and the bounded, are not homogeneous, but nevertheless cognate or "homogonous".

This concept of "change as homogonous variation” is arguably the most profound and most problematic for Plato.
