Chris, I've read 4-5 ethnobotony books but feel they aren't much use for people starting out in edible wild plants. The books are very regional-specific and don't give much information on identifying the plant. For the same reasons I steer novices away from euell Gibbon's books. The only ethnobotony book I've included on my rec-list is Tull's Edible and Useful Plants of Texas and the Southwest: A Practical Guide. It covers all sorts of Native Texan use of local plants (food, dyes, fiber, fish poison, etc). This book is poorly written and hard to use but it's the only one specific for my area.

My recommended references link seems to be flakey. Some people can see the books, others can not. I'm not sure why. I contacted Amazon as it is their widget, but they said "We can see the list so it's not our problem."
