This volume serves as a comprehensive taxonomic reference for the diverse tree species found within the borders of Nigeria. Author R. W. J. Keay, a recognized authority in tropical botany, synthesizes decades of research to update the nomenclature and classification of nearly one thousand tree species. By consolidating previous multi-volume works into a single, accessible text, the book provides a streamlined resource for identifying both native and introduced flora through a rigorous botanical framework.

Botanists and researchers frequently cite this work as the definitive reference for Nigerian dendrology. Experts highlight the text for its technical precision and its utility in bridging the gap between local vernacular naming conventions and formal scientific taxonomy.
