About Persicaria maculosa-type

I recently found a pollen of Persicaria maculosa-type. I didn’t know about this type before, and as the grain was not well preserved and folded, at first I thought about Armeria. But I wasn’t convinced about that, specially given the details provided by the Flora Helvetica, which didn’t fit with the study site at all, even long time ago. Hopefully, thanks to colleagues, we came to identify it as the old Polygonum persicaria-type. Looking in tela botanica, I found that Polygonum persicaria is now known as Persicaria maculosa, and is common at my study site. And finally, I found the Persicaria maculosa-type in Beug (2004)!
