"Plant Systematics with Practical Angiosperm Systematics" by Swapnil Yadav is a comprehensive and syllabus-aligned textbook meticulously crafted for undergraduate students of Botany pursuing their 3rd-semester minor and 4th-semester major courses at Dibrugarh University and 5th-semester major courses at Gauhati University and Other Indian Universities under the FYUGP NEP and CBCS frameworks.

The book provides a scientific understanding of plant taxonomy, with a strong focus on the classification, nomenclature, and identification of angiosperms (flowering plants). It combines both theoretical knowledge and hands-on practicals, making it especially beneficial for students preparing for lab-based work and field studies.
