Hello Ian,
I doubt there is any possibility to mix up Iris ruthenica and Iris lactea:
1) first have grassy shining wilting leaves, second have rigid upright mat
bluish-green leaves
2) first is plant of clear forests and mountain meadows, second grow on
salt-ridden meadows on the banks of rivers and lakes
3)traditional areal of Iris lactea is South Siberia east of lake Baikal,
Russian Far East, North-east Mongolia and North China (sorry I don't know
much about new researches of Zhao in China), so it could not be found at
Altai Mountain far western of lake Baikal
4)I don't compare near round boll of ruthenica and spindle-shaped boll of

I think too there is possibility to mix up the flowers of lactea and some
sibiricas at first sight, but never very chracteristic flowers of spurias.

I add a link to photo of siberian Iris lactea:
