William Austin Cannon's book "Botanical Features of the Algerian Sahara" is a thorough investigation of the flora present in Algeria's Sahara desert region. The book focuses on the local environmental elements that affect plant growth, such as the arid desert climate, different soil types, and water availability. The study of Cannon offers a thorough analysis of the many plant species discovered in the Algerian Sahara, together with descriptions of their physical traits and adaptations to the hard desert environment. He also talks about how local people have traditionally used plants for food, medicine, and other things. Cannon emphasizes the necessity for conservation efforts to secure the survival of these species throughout the book and the significance of preserving the distinctive flora of the Algerian Sahara.
