UC Irvine maintains an archive of about 75 classification
problems including the iris database.

The iris data can be retrieved by anonymous ftp from ics.uci.edu
It is in pub/machine-learning-databases/iris/*

I suggest also retrieving pub/machine-learning-databases/OVERVIEW
for a descrription of the files.

We are always looking for additional datasets that can be used to test
various algorithms.
