Please do not write to us about Prorocentrum compressum (J.W.Bailey) Abé ex J.D.Dodge, supposedly a dinoflagellate, being a taxonomic synonym of Tryblionella compressa (J.W.Bailey) Poulin, supposedly a diatom. It is indeed an unusual case, but there was a difference of opinion as to the identity of the basionym Pyxidicula compressa J.W.Bailey, some authors treating it as a diatom and other as a dinoflagellate; the consensus now is that it is a diatom.
Please do not write to us about the change of spelling of Zostera noltii to Zostera noltei. The orthography "Noltii" was originally used by Hornemann to honour Ernst Ferdinand Nolte (1791-1875). Under the current International Code of Nomenclature the genitive singular honorific for a name ending in "e" is to add an "i" and not to delete the "e" and to add "ii". There is no point in writing to me to complain about this. All four higher plant names honouring Nolte are currently spelled "noltei".
