Baltisphaeridium trifurcatum subsp. procerum Appendix A
From dinoflaj2
"subsp. procerum" (Sannemann, 1955, p.332, pl.5, fig.8; text-fig.18) Downie and Sarjeant, 1965, p.98. Holotype: Sannemann, 1955, pl.5, fig.8. NOW Multiplicisphaeridium procerum (Appendix A). Originally Hystrichosphaeridium trifurcatum subsp. procerum, subsequently Baltisphaeridium trifurcatum subsp. procerum, thirdly (and now) Multiplicisphaeridium procerum (Appendix A). This combination was not validly published in Downie and Sarjeant (1963, p.90), since these authors did not fully reference the basionym. Age: Devonian (Late Givetian). Parent: Baltisphaeridium trifurcatum
