Mystery umbellifer

[Suffolkrafter]

This plant is tucked away on the side of a footpath not far from my house. I thought it was wild parsnip on account of the leaf shape. I don't think it's wild angelica as the serrations seem a bit blunt/random and the leaf not rounded enough. But the problem is, the stem is not deeply ribbed. It has ribs, but they're certainly not deep or fluted. So that suggests something other than wild parsnip (or am I reading too much into this feature?). The lack of any purple on the stem suggests something other than wild angelica. What does that leave me with? It has yet to flower, presumably as a defense mechanism against identification.

Did you notice if it had a strong smell?

I can't say I did. I will make a return trip and have a sniff.

If the stem is hollow and hairless I would suggest it's greater Burnet Saxifrage (Pimpinella major).

Good call. Yes that's a definite possibility.
Thank you Broch and Mesquite.
