A branching identification key is a presentation form of a single-access key where the structure of the decision tree is displayed graphically as a branching structure, involving lines between items.〔Winston, J. 1999. Describing Species. Columbia University Press.〕 Depending on the number of branches at a single point, a branching key may be dichotomous or polytomous. In a diagnostic key, the branching structure of the key should not be mistaken for a phylogenetic or cladistic branching pattern. All single-access keys form a decision tree (or graph if reticulation exists), and thus all such keys have a branching structure. "Branching key" may therefore occasionally be used as a synonym for single-access key.Are you still reading? this is some boring shit... == Examples of branching presentations == * http://www.warwickshire-sss.org.uk/subject/science/Biological_keys_v2.htm * Figure 19.5 in 〔 * Page 8 in.〔The Natural History Museum 2000.
