Branching tree

Definition

noun

A branching identification key where the structure of the decision tree is displayed graphically as a branching structure, involving lines between items.


Supplement

Depending on the number of branches at a single point, a branching key may be dichotomous or polytomous.

"Branching key" may therefore occasionally be used as a synonym for single-access key.
