A concise aesthetically pleasing numbered copy on the use of plants in the Practice or Craft. The author introduces a fair amount of lore on the subject in this short treatise complete with citations (e.g., footnotes and two page bibliography).
Essentially Boyer adds some bits of information the reader had not known or wets their appetite for more and points them towards the next destination in their botanical journey. Book is well constructed and attractive, though some may wince at its cost in comparison to its size.
