Originally Hystrichosphaeridium, subsequently Baltisphaeridium, thirdly Hystrichokolpoma (combination not validly published), fourthly Achomosphaera, fifthly Silicisphaera, sixthly (and now) Florentinia. This combination was not validly published in Downie and Sarjeant (1963, p.92), since these authors did not fully reference the basionym. Age: Cretaceous.
