[200] Huxley. A. The New RHS Dictionary of Gardening. 1992. 1992.
Excellent and very comprehensive, though it contains a number of silly mistakes. Readable yet also very detailed.
[257] Moerman. D. Native American Ethnobotany 1998.
Very comprehensive but terse guide to the native uses of plants. Excellent bibliography, fully referenced to each plant, giving a pathway to further information. Not for the casual reader.
