SPECIALTY PLANTS
The Genus Arisaema (by Guy and Liliane Gusman) Timber Press, 2006.
 

  For those who want to know everything about the fascinating world of this genus (that includes our native Jack-in-the-pulpit, Arisaema triphyllum), this is the book you need.  The authors have trekked across the world viewing these plants in their varied habitats and have spent years growing them and studying their biology. The 474 pages include excellent photographs and extensive information.  Although academic in tone, it is accessible to plant lovers of any kind.  Highly recommended.
