Worth buying just for Ott's detailed notes and bibliography. Although it almost duplicates the Ayahuasca information in Pharmacotheon, Ayahuasca Analogues has the advantage of being pocket sized - in price and dimensions. A reference book for over 1000 flowering bulbs, corms, tubers and rhizomes from all over the world. Text is minimal, but useful. The plant photographs illustrate the most distinctive features of each species or variety.
Text is minimal - species are listed by genus name in alphabetical order.
