'Sturtevant's edible plants' is Victorian ethnocookery listmania in hyperdrive. It is a collection of notes on what plants and what part of plants are eaten where and how. You can take almost any plant, look it up and learn how the Greeks or the Indians used it. The information was collected by US Botanist Sturtevant in the late 19th century but only edited for publication after his death in 1919. It is an outdated collection of lore but a fascinating place filled with all sorts of exotic factoids of interest to contemporary foragers. It is out of print but you can find copies of the Dover reprint, however this book that makes more sense as a searchable PDF.
