Was Iris collina - now Little yellow iris & more

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 -

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

Dear Peter and all,

There's a number of topics here so

1. You should read Brian Mathew's article in the BIS year book called
"Little Yellow Iris' or simlar. There's a number of such plants from China
to E. Europe that have been confused in the literature, but seem quite
distinct in life. I have seen most of these in the wild. I. mandschurica is
a Pseudoregelia, I flavissima is a Psammiris, Iris arenaria is also a
Psammiris and may be the western form of I flavissima. I humilis has been
applied to various species from PCN to spuria to bearded. The latest BIS
version calls it the same as I arenaria.

There is no comparison with I sintenisii.

2, The dwarf yellow flowered spuria that is superficially similar to the
true I sintenisii is probably I kerneriana. It is a very delicate spuria
with clear yellow flowers. Fairly easy from seed.
