Umbellifer, grass & thistle for ID

All growing today on the banks of the Thames in Berkshire. Any IDs would be greatly appreciated

this was prolific and was about 4.5 - 5ft high.

I'm sure this is really obvious

4.5 - 5ft high again

I wouldn't swear to either of these ids, but I think the grass is wood small-reed Calamagrostis epigejos and the thistle is welted thistle Carduus crispus (C. acanthoides as was)

Thanks treecreeper

welted thistle Carduus crispus is one name that I'd considered so your suggestion makes it more probable.
I'm not convinced on wood small-reed Calamagrostis epigejos, though. Looking at pictures on the web it looks quite different. Maybe it's at a different stage of it's growth/cycle?

Agree with Welted Thistle.

Unfortunately your other good photos don't show features such as leaves + general appearance of the plants which are useful when IDing from pictures.

The umbellifer flowers look like Coriander to me, which is an increasing casual.

Agreed with Welted Thistle.

The flowers look like the wrong shape for Coriander but look a lot like Common Hogweed

You're right! Just illustrates my point- if the leaves were present it would have been so obvious. I was thinking along more obscure lines rather than looking for the common!
