This is one of many species which I suspect I would overlook even if I was lucky enough to see it. As far as I know we have no recent Glamorgan records but there are several historic ones, so perhaps as a group we are guilty of passing it over as O. hians (unless it's declined, or is just very rare in the county).
Any tips on where to look and what to look for would be appreciated. I'd imagine the underground stems, mentioned as a key feature in the field guide, would not always be easy to extract in the field.
Information and photos would be welcome, thanks!
