List 11 and 12 references

  1. Brockman, C. (2002). Trees of North America: A Guide to Field Identification. New York, NY: St. Martins Press.

This book was helpful in identifying a number of the plants on the last two lists. The descriptions were complete included all the necessary information. Illustrations were clear and helped identify key features of each tree. A good resource that I would recommend.

2. http://www.sfbotanicalgarden.org/

This website from the San Fransisco botanical garden offered a lot of information about the plants that were available. Not all plants on the list were available here however I would recommend this list as it was inclusive with good images.

3. http://www.chicagobotanic.org/plantcollections#plantfinder

This website was particularly well organized and easy to maneuver. It again had a number of the plants listed and was easy to access the various areas of the website. I would recommend this for further use.
