Plant taxonomy is the science that finds, describes, classifies, identifies, and names plants. It thus is one of the main branches of taxonomy. It is closely allied to plant systematics, and there is no sharp boundary between the two. In practice, "Plant systematics" is involved with relationships between plants and their evolution, especially at the higher levels, whereas "plant taxonomy" deals with the actual handling of plant specimens.

The book is well illustrated and is comprehensive and dependable text for undergraduate and postgraduate students of botany. Students will find information on important herbaria and botanical gardens useful.
