​”A Manual of Poisonous Plants, Part 2″ by L.H. Pammel is a comprehensive continuation of his earlier work, focusing on the identification and classification of toxic flora, particularly those found in eastern North America. Published in 1911, this volume serves as an extensive reference for botanists, agriculturists, and medical professionals concerned with plant toxicity. Pammel’s meticulous approach includes detailed descriptions, illustrations, and notes on the economic and medicinal aspects of various plants, reflecting the scientific rigor of the early 20th century.​

The book systematically catalogs poisonous plants, providing insights into their botanical characteristics, habitats, and the nature of their toxic properties. Pammel emphasizes the importance of understanding these plants not only for academic purposes but also for practical applications in agriculture and medicine. His work underscores the necessity of recognizing and managing plant-related risks to both humans and livestock, a concern that remains relevant today.​

In addition to the detailed plant profiles, Pammel includes a global catalog of poisonous plants, arranged alphabetically by family. This section offers a broader perspective on plant toxicity, highlighting the universal nature of the issue. The inclusion of a comprehensive bibliography with over a thousand entries further enhances the book’s value as a scholarly resource, providing readers with avenues for deeper exploration into the subject matter.​

Pammel’s work stands as a testament to the enduring importance of botanical studies in understanding and mitigating the risks associated with poisonous plants. By combining scientific detail with practical insights, “A Manual of Poisonous Plants, Part 2” continues to be a valuable resource for those interested in plant toxicology and its implications for health and agriculture.​
