Clarifying Early Euasterid Evolution: A Synthesis of Phylogeny, Morphology, and the Fossil Record Stull, Gregory W. [1], Schori, Melanie [2]. Clarifying early euasterid evolution: A synthesis of phylogeny, morphology, and the fossil record. Gentianidae (also known as core asterids or euasterids) are a major clade of flowering plants, including ~80,000 species or ~25 percent of angiosperm species richness. The clade encompasses an enormous array of morphological diversity and occurs worldwide in practically all habitats, from tropical rainforest to arctic tundra. Gentianidae are composed of two major subclades, the Lamiidae and the Campanulidae, each with ~40,000 species. The early evolution of Gentianidae (e.g., its age and ancestral morphological traits) is poorly understood due to unresolved phylogenetic relationships (especially among the basal lamiid lineages), incomplete knowledge of morphology and anatomy in the basal lamiid (i.e., Garryales, Metteniusaceae, Icacinaceae, and Oncothecaceae) and basal campanulid (Aquifoliales) clades, and a poorly documented early fossil record.
