Tripleurospermum maritimum subspecies

I notice that both ssp nigriceps and ssp phaeocephalum are listed on the database, both with a handful of records in British Isles, including one of each for VC111. I understand that ssp nigriceps is the current name for the BI taxon formerly named ssp phaeocephalum, and that ssp phaeocephalum now correctly applies to a different, Arctic, taxon. Hence older records (except one) in DDb go by the older name and more recent records by the new one. Should the taxonomy not be up-dated in DDb? The one exception is a record from Harris in 2003 that goes by both names!

your interpretation matches Sell's Flora (as well as Stace).

I've updated the entry for subsp. phaeocephalum to mark it as a synonym of subsp. nigriceps (and changed it's authority to auct. non)
