Couple more plants for id/confirmation please!

[JennyS]

Still sorting through the last couple of days photo's and came across (surprise,surprise!) a couple more I'd be glad of confirmation or suggestions on.....

1. Hemlock, Conium maculatum, but are there any other white-flowered umbellifers that can also have purple/purple-spotted stems?



2. Heath/Wood Groundsel, Senecio sylvaticus?



3. Groundsel, S.vulgaris, but very bulbous bases.....



4. A much bigger than usual Trefoil, and the ground where it was growing didn't seem excessively fertile from the size of other plants there. It was the elongated fruit that caught my attention?

Agree with your first 3 IDs; not so sure about trefoil from photo! A possibility could be Large Trefoil, T.aureum, but it's not a plant I've seen - it's naturalised in some places.

The last is Black Medick, Medicago lupulina.
Tiny tooth in the angle at the tip of the leaf, and fruits losing the covering of the dead flowers and starting to turn black.

Other IDs fine.

Thank you both - I had been hoping that last one might have been Large Trefoil - the difference in growth and appearance on different soils keeps throwing me ..... at least this time I had the sense to check first!
