Polysporangiophytes are plants with a structure of branching axes terminating in sporangia. This includes most land plants (embryophytes) except for the bryophytes. Its definition is independent of the presence of vascular tissue. The earliest known polysporangiophytes are genera such as the famous "Cooksonia" and "Aglaophyton".
