Parsimony analysis (cladistics) has long been one of the most widely used methods of phylogenetic inference, in the fields of systematic and evolutionary biology. Moreover it has mathematical attributes that lend itself for use with complex, genomic-scale data sets. This book demonstrates the potential that this powerful hierarchical data summarization method, also has for both structural and functional comparative genomic research.

This volume provides a comprehensive review of the family, Gentianaceae, covering phylogeny, classification, biogeography, palynology, phytochemistry, and morphology, and also presents the first classification of the entire family to be published for over 100 years, generated using modern molecular- and morphology-based phylogenetic data. The volume places the Gentianaceae in context with its relatives in the order Gentianales and subclass Asteridae; presents an updated, phylogenetic classification of tribes, subtribes, and genera; investigates the corroborative value of morphological features in phylogenetic diagnoses; and comprehensively summarizes palynology, seed morphology, and phytochemistry.
