Not sure

Doesn't look hairy enough for E. parviflorum. Could it be E. lanceolatum?

Lanceolatum

Thanks landgirl; wondered about that, but "Rose" suggests it has leaves that taper into long stems, whereas this example appears to have almost no leaf stem. John

Are you sure that ...

... the stigma is 4-lobed (it doesn't look like it in the photograph, but the suberect lobes of E. parviflorum are known to give problems)?

I've got to refresh my Epilobium identification skills, but I would suspect E. ciliatum.

Principal Diagnostics

Obviously no clear answer to this "conundrum", given the range of possible IDs; it seems to me that the example doesn't really fit any of them uniquely.

"lanceolatum" apparently has alternate leaves with tapering bases and longish leaf stems. "parviflorum" is apparently hairier and often seems to have grey-green leaves. "ciliatum" has an undivided club stigma, deeply notched petals and apparently often has darker tips to petals.

On original observation, I was pretty sure that the stigma wasn't club, but unfortunately the specimen has been removed, so can't review that element of the possible ID. Perhaps it is not possible to conclude "safely".
