Talk:Vitrella

Chlorophyll a
Forms having only chlorophyll a might be linked taxonomically, but the taxon would be polyphyletic, as the trait is plesiomorphic, and such forms are not rare, as red algae have 4000 species. The sentence in question in the Introduction should be removed. --Capt. Ciel (talk) 16:56, 26 September 2020 (UTC)
