Parts of a Dendrogram
dendrogram
A dendogram can be a column graph (as in the image below) or a row graph. Some dendograms are circular or have a fluid-shape, but software will usually produce a row or column graph. No matter what the shape, the basic graph comprises of the same parts:
The clade is the branch. Usually labeled with Greek letters from left to right (e.g. α β, δ…).
Each clade has one or more leaves. The leaves in the above image are:
Single (simplicifolius): F
Double (bifolius): D E
Triple (trifolious): A B C
A clade can theoretically have an infinite amount of leaves. However, the more leaves you have, the harder the graph will be to read with the naked eye.
