Since there is a page for each Iris name The Table below provides a good estimate of all irises named.
|All types of Iris||63,223|
|Total Beardless, and all species||10,156|
|Aril + Arilbred||2227|
These numbers are compiled by counting the pages for each in the Encyclopedia for each category:
Surprisingly a few are still alive and well in gardens and even have images attacged.
So what is the bottom line? As the wiki becomes more and more developed The numbers will probably be slightly greater than actual based on the number of pages, but for now the numbers probably balance out and provide a good estimate.
