Epilobium obscurum Short-fruited Willowherb CC DD N
We spent some time looking for the glandular hairs on the hypanthium (the funnel shaped bit of the flower above the ovary but below the open petals) because this is supposed to be the determining characteristic of Epilobium obscurum according to our expert. At first I couldn't see any but persistent examination revealed a few - these willowherbs can be difficult. The ovaries which become fruits don't seem particularly short-fruited to me but what do I know?
It is found just about everywhere in the British Isles and I have to admit I've never noticed it before. But then without a x 20 hand lens you wouldn't be able to confirm identification.
