Could someone direct me to a good site for identifying cactus and succulents? I have tried search but haven't found much. Thank you.

Try the site below. The on-line catalog has lots of pictures & names. Join the Cacti & Succulent Society http://www.cssainc.org; they have excellent materials and a great magazine.
