"The Useful Trees of Northern Nigeria" by Hugh Vandervaes Lely is a guide detailing tree species of Northern Nigeria's savannah forests in the early 20th century. Lely's book, intended for botanists and those interested in ecological conservation, aims to offer practical guidance for identifying 120 different species. Organized alphabetically, each entry describes morphology, habitat, and economic uses and is supported by detailed drawings of leaves, flowers, and fruits with notes on human impacts to the local ecosystem.
