Yes, mine do look like iris-foetidissima, the "stinking" iris your link shows.
After someone earlier suggested Montbretia I googled them and saw something with red berries that looked a bit like my mystery iris-like plant.
I then dug up several more plants which had both the leaves and roots in my two photos but this time attached to each other.
whilst the leaves and the root do clearly belong together I guess my mistake is In wrongly attributing both to the wrong name.
i just don't know enough about plants to recognise wrong information. Thanks for everyone's help.
However, I did also dig up today these clusters of corms. Are those Montbretia?
