See it in a sentence

Early botanists grouped palms and grasses together as endogens because of how their stems grow.

The textbook's outdated chapter still divides plants into endogens and exogens.

A note on using this word

The endogen/exogen classification, based on Greek endon ('within') and exo ('outside'), was largely replaced by the modern monocot/dicot system, so the term now appears mostly in historical botanical texts.
