Gerhard, in Brian Mathew's 'The Iris' he has Iris humilis as a synonym of I. pontica.
"Dwarf tuft forming species about 10cm in height when in flower but with over-topping grassy leaves 2-4cm wide and upto 20-40cm long. Solitary flowershave stems only 1-4cm long and about 5-6cm in diameter with nearly orbicular blades to the falls, separated from the winged claw by a definite constriction. Flower colour is violet with whitish or pale greenish-yellow, vilet-veined area on the haft and the centre of the blade of the falls, and the whole flower is finely darker-veined. Capsule produced at or justabove ground level. It occurs in dryish steppe country in central and north-eastern Roumania, western Ukraine and the Caucuses, possibly extending eastwards into Russian Central Asia although it's exact distribution does not seem to be well known"
I hope this helps.

The BIS Species group book A Guide to Species Irises says:
I. humilis Georgi syns I arenaria Waldst. & Kit., I flavissima Pall., I. falvissima subsp. stolonifera, I pineticola
Extensive from Austria east through central Europe to south-east Russia, Siberia, Rumania and Mongolia.
Flower: buds sometimes greeen touched with bronze; 3-4cm diameter; falls to 3.5cm long, 1.2cm wide, bright yellow; oblong blade rather shorter than halft, which is veined browish purple, haft horizontal; beard orange, club-shaped hairs tipped brown; standards to 3cm long, about 0.3cm wide, oblong, unguiculate, yellow brown-purple edging on haft and shorter than falls; styles to 2.5cm, narrow, crests short, triangular, acutely tipped; stigma entire; filaments colourless, same length as anthers; anthers cream with green-black edging; pollen greenish.
Now please don't ask me to type out the rest of the description!! :)
It does say at the end that Mathews has not found the plant easy.
Iris humilis Beechy is also a synonym of I. douglasiana Herbert,
I. pontica Zapalowicz has I humilis Bieb., as a synonym
I unguiculars subsp,cretinsis has I humilis Sieber ex Baker [nom.in schaed.] as a synonym too
