Iris collina resurrection

I find the local forms of Iris fascinating, so much information is lost
when the names of regional variants are sunk as synonoms!

Many of the plants in circulation in Britain as Iris humilis are in fact a
small spuria which I presume is Iris sintenisii, but may be pontica?  (Iris
humilis is also a small yellow Iris, varying in size across its
distribution and not a spuria).
Iris pontica does not appear to be in circulation in Britain judging by the
comments below, as all the plants I have seen, and that I have grown from
seed, have narrow, upright leaves about 12 inches high, amongst which are
buried the flowers. The leaves of these plants do bend over to make a
cushion effect at the end of the growing season.
