That's Not a Cactus!
All cacti are succulents, but not all succulents are cacti. If you are having a hard time identifying your
"cactus" plant, be sure to use the Cacti or Not? page to rule out
other succulents. You might be surprised when you find out that your very cactus-looking plant turns out not to be
cactus at all.

Updated Terminology Page
Check out the all new Glossary of terms that is full of useful
words and definitions that are related to cacti. Also find out "What's in a name" by visiting the Cacti
Etymology pages. Learn how a cactus plant got it's name or what the name means. One page covers the different
genera while the other handles the
species names.

The overall function of this site will be simply a cataloging
of the different species in the family Cactaceae. The primary purpose
is to include detailed photos as accurately as possible for the positive
identification of a particular species. As a cacti enthusiast, I found
that sometimes identifying a particular cactus species can be very difficult.
Many sources have a limited number of photos or the photos are mostly
close-ups of flowers. To add to the challenge, many sources have conflicting
information on nomenclature. Therefore
it is my hope that this site will not only be a rewarding hobby for
me, but also serve as a useful resource for other cacti enthusiasts.
Note: I try not to post a picture unless I am relatively
positive that I've identified it correctly. This does not mean that
this site is free from mistakes. If you see a mistake, please don't
hesitate to send me an e-mail
and I will fix it.
Fun Feature: We have cactus picture contests on the CactiForum. Be sure to at least
take a look at the first place winners on this page.
