Edible and Useful Plants of the Southwest
All around us there are wild plants useful for food, medicine, and clothing, but most of us don’t know how to identify or use them. Delena Tull amply supplies that knowledge in this book, which she has now expanded to more thoroughly address plants found in New Mexico and Arizona, as well as Texas. Extensively illustrated with black-and-white drawings and color photos, this book includes the following special features: Recipes for foods made from edible wild plantsWild teas and spicesWild plant dyes, with instructions for preparing the plants and dying wool, cotton, and other materialsInstructions for preparing fibers for use in making baskets, textiles, and paperInformation on wild plants used for making rubber, wax, oil, and soapInformation on medicinal uses of plantsDetails on hay fever plants and plants that cause rashesInstructions for distinguishing edible from poisonous berriesDetailed information on poisonous plants, including poison ivy, oak, and sumac, as well as herbal treatments for their rashes

Poison arrows : North American Indian hunting and warfare
Biological warfare is a menacing twenty-first-century issue, but its origins extend to antiquity. While the recorded use of toxins in warfare in some ancient populations is rarely disputed (the use of arsenical smoke in China, which dates to at least 1000 BC, for example) the use of “poison arrows” and other deadly substances by Native American groups has been fraught with contradiction. At last revealing clear documentation to support these theories, anthropologist David Jones transforms the realm of ethnobotany in Poison Arrows. Examining evidence within the few extant descriptive accounts of Native American warfare, along with grooved arrowheads and clues from botanical knowledge, Jones builds a solid case to indicate widespread and very effective use of many types of toxins. He argues that various groups applied them to not only warfare but also to hunting, and even as an early form of insect extermination. Culling extensive ethnological, historical, and archaeological data, Jones provides a thoroughly comprehensive survey of the use of ethnobotanical and entomological compounds applied in wide-ranging ways, including homicide and suicide. Although many narratives from the contact period in North America deny such uses, Jones now offers conclusive documentation to prove otherwise. A groundbreaking study of a subject that has been long overlooked, Poison Arrows imparts an extraordinary new perspective to the history of warfare, weaponry, and deadly human ingenuity.

Poisonous Plants Species Prediction Using a Convolutional Neural Network and Support Vector Machine Hybrid Model
The total number of discovered plant species is increasing yearly worldwide. Plant species differ from one region to another. Some of these discovered plant species are beneficial while others might be poisonous. Computer vision techniques can be an effective way to classify plant species and predict their poisonous status. However, the lack of comprehensive datasets that include not only plant images but also plant species’ scientific names, description, poisonous status, and local name make the issue of poisonous plants species prediction a very challenging issue. In this paper, we propose a hybrid model relying on transformers models in conjunction with support vector machine for plant species classification and poisonous status prediction. First, six different Convolutional Neural Network (CNN) architectures are used to determine which produces the best results. Second, the features are extracted using six different CNNs and then optimized and employed to Support Vector Machine (SVM) for testing. To prove the feasibility and benefits of our proposed approach, we used a real case study namely, plant species discovered in the Arabian Peninsula. We have gathered a dataset that contains 2500 images of 50 different Arabic plant species and includes plants images, plant species scientific name, description, local name, and poisonous status. This study on the types of Arabic plants species will help in the reduction of the number of poisonous plants victims and their negative impact on the individual and society. The results of our experiments for the CNN approach in conjunction SVM are favorable where the classifier scored 0.92, 0.94, and 0.95 in accuracy, precision, and F1-Score respectively.

Relationship Between the Endophyte Embellisia spp. and the Toxic Alkaloid Swainsonine in Major Locoweed Species (Astragalus and Oxytropis)
Locoweeds (Astragalus and Oxytropis spp. that contain the toxic alkaloid swainsonine) cause widespread poisoning of livestock on western rangelands. There are 354 species of Astragalus and 22 species of Oxytropis in the US and Canada. Recently, a fungal endophyte, Embellisia spp., was isolated from Astragalus and Oxytropis spp. and shown to produce swainsonine. We conducted a survey of the major locoweeds from areas where locoweed poisoning has occurred to verify the presence of the endophyte and to relate endophyte infection with swainsonine concentrations. Species found to contain the fungal endophyte and produce substantial amounts of swainsonine were A. wootoni, A. pubentissimus, A. mollissimus, A. lentiginosus, and O. sericea. Astragalus species generally had higher concentrations of swainsonine than Oxytropis. Swainsonine was not detected in A. alpinus, A. cibarius, A. coltonii, A. filipes, or O. campestris. The endophyte could not be cultured from A. mollissimus var. thompsonii or A. amphioxys, but was detected by polymerase chain reaction, and only 30% of these samples contained trace levels of swainsonine. Further research is necessary to determine if the endophyte is able to colonize these and other species of Astragalus and Oxytropis and determine environmental influences on its growth and synthesis of swainsonine.
