Thankyou for the correction Jim, I confused the Pseuduregelias with the
I do have a couple more Psammiris  species but this is the only picture
which I have at this moment -
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?

There are also a couple of Iris here which I would like to identify....
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!
Again... thanks
