First, let's talk about Irids.
The Family Iris contains about 80 genera, one of which is the Genus Iris. The other genera are collectively refered to as Irids -- which means "Iris-like plants". With only a few exceptions they are geographically restricted rather than widespread across the globe like Iris. These genera are sometimes small and subject to reclassification, occasionally being absorbed into larger genera. The list below includes those larger more stable genera.
