A few words about the maps, photos and scans on these pages.


The distribution areas show in green on the maps are not are to be taken too literally. These maps simply show the states or provinces where each species can be found. Irises don't easily follow these political boundaries.For example a green State of Texas for I. brevicaulis means that this speciesis reported SOMEWHERE in Texas. You'll be disappointed if you expect to find any native Irises when you visit San Antonio. (Go East young man!) I would like to provide more detailed maps but the information is not readily available. There are links to more detailed information where available. Special thanks to Ian Efford for information about the distribution of the Canadian species, and too all those who have sent their comments and corrections.


Thanks to the individauls who have contributed photos. Below is a list of the photographers linked to web sites or e-mail address (I've grouped them to make keeping the links current easier.) Please contact to request use of their photos.

Special thanks to the BerkeleyDigital Library Project for use of the PCNI photos from the BrousseauCalifornia Flora Pictures. These photos are copyrighted, but most are available for nonprofit use.

The photos with no credit given are taken in my garden in North Central Texas. The quality has improved since aquiring my digital camera, but some older photos are still here. My photos are also available for nonprofit use. Please ask.

Please make a contribution to this effort by sending me quality photos of any of the species. Photos of flowers, various color forms, foliage, seed pods and iris in their native habitat are all of interest.

Direct  Scans

These are flowers from my garden scanned directly on my Epson scanner. The scale is 1 to 1 except were noted.  The images may not appear life size due to your monitor resolution setting.  The colors have been corrected to the closest match I can manage on my monitor.  The color may appear different on your monitor due to it's calibration.  Generally there is one scan of the intact flower attempting to make the flower parts visible while retaining the basic flower form.  Another scan is done with one set of flower parts removed, as you might find on a herbarium sheet, to make the individual parts more visible.

Your comments and questions are welcome!
