Branched flowering stems, leaves with very few hairs so appearing smooth.
No interactions present.
flowering stems look like L. autumnalis as you have it, but leaves more like L. hispidus to me
Whatever they are they are all over the place! Hairs don't bifurcate and stems are branched so I ruled out Rough Hawkbit. I think there is both Rough and Lesser Hawkbit elsewhere but not so apparent at the moment.
Scorzoneroides autumnalis (as it is now) is variable, with a number of named varieties. These leaves, however, are to me virtually typical of the species - certainly well within the range of variation.
Indeed, it is very good S. autumnalis var. autumnalis on leaf and capitulum characters.
Thanks for confirming that Alan. It's very helpful because I can now estimate how abundant they are and they are an indicator species for Priority Habitat Lowland Meadow.
