Cactaceae on-line
 

With the recent overhaul of the Opuntioid genera as well as the naming of a
number of new species, all the available field guides are now completely
out-of-date. Its about time for something newer than Lyman Benson's 1983
monograph anyway.

Do not use the internet as your primary source of information either. Most
of the pictures on-line are posted by amateur entusiasts and many are either
with obsolete names or misidentifed.

American cactus? hard to tell online if the illustrations are any good
before i buy.
