Glossary of "Cladistics (2nd ed.)" by Kitching et al. (1998)
- Two character states within a multistate character are adjacent if they are placed next to each other in a transformation series. For example, in the transformation series 0 <-> 1 <-> 2, states 0 and 1, and 1 and 2, are adjacent. Cf. non-additive coding.
