The general form and flowers (size and number) don't seem right for F. muralis.
I'm leaning towards F. officinalis, but it's an awkward genus; the fine details of the sepals, leaves and fruits often need to be examined to be confident of the species.
not easy to make a confident call. I've looked at the others that are linked - what do you think of them?
The first looks good for F. muralis and I've agreed. I'm not familiar with F. parviflora, but wouldn't go off leaf shape alone.
There is a good key here:
Also, Fumitories of Britain and Ireland by Rosaline J. Murphy provides a good account, but I don't own a copy.
I'm now based in London and hoping to find time to get back to the enjoyment of lichen hunting. Trust you'll be able to advise as before.
Good to hear from you, and happy hunting. I'll certainly keep an eye out.
but I seem to have trouble reading PDF files directly off the Internet - shall try to find a solution.
Identifying fumitory's down to species level requires close observation of the plants sepals. Size and shape are key factors. Also useful though not diagnostic is the plants location, e.g arable, coastal etc and where in the country it was found. Some species are extremely local.
