basal eudicot

The term "basal eudicot" refers to plants that are more primitive within the eudicot group, which is one of the two major divisions of flowering plants (angiosperms). Eudicots are characterized by having two embryonic leaves, or cotyledons, in their seeds.12

Unlike the more derived "core eudicots," basal eudicots and monocots share a simpler pollen structure with a single furrow or pore (monosulcates). In contrast, eudicots typically have pollen with three furrows or pores (tricolpate). While core eudicots often exhibit a more standardized floral structure with parts in multiples of five, basal eudicots show greater variation in their floral morphology.12
