Thankyou for the correction Jim, I confused the Pseuduregelias with the Psammiris. I do have a couple more Psammiris species but this is the only picture which I have at this moment - http://flickr.com/photos/organize/… of what I believe is Iris humilis. I did once grow a very small form from seed but it died out after about five years. It was identified by Brian at the RHS/Iris committe. As you point out, it is very hard to get these plants accurately identified when one is unable to reference a range of material Perhaps you might confirm or otherwise this spuria? http://flickr.com/photos/organize/… There are also a couple of Iris here which I would like to identify.... http://flickr.com/photos/66380714@N06/… http://flickr.com/photos/66380714@N06/… http://flickr.com/photos/organize/… I do not have a picture of Iris kerneriana as I grow it, but I am confident of its identity and it has much larger, more spindly flowers than the other small spurias which I know. I do have the booklet you refer to, and shall be referring it as these plants come into growth!
