Polygonium polygonale Appendix A

polygonale (Eisenack, 1931, p.113, pl.4, figs.16–20; pl.5, fig.18 ex Eisenack, 1938a, p.12) Le Hérissé, 1989, p.182.  Holotype: Eisenack, 1931, pl.4, fig.19, as Ovum hispidum subsp. polygonale, lost according to Eisenack (1959, p.199).  Neotype: Paris and Deunff, 1970, pl.1, fig.4, as Veryhachium splendens, designated by Fensome et al. (1990, p.235), which see.  Originally Ovum hispidum subsp. polygonale (name not validly published, Appendix A), subsequently Hystrichosphaeridium polygonale, thirdly Baltisphaeridium polygonale (Appendix A), fourthly Veryhachium polygonale (combination not validly published, Appendix A), fifthly Goniosphaeridium polygonale (Appendix A), sixthly (and now) Polygonium polygonale.  Taxonomic junior synonyms: Impletosphaeridium? primordiale, according to Eisenack et al. (1973, p.497–498); Veryhachium (subsequently Goniosphaeridium) splendens Paris and Deunff, 1970, an acritarch species, according to Turner (1984, p.113–114), who believed Goniosphaeridium splendens to be the senior name; Hystrichosphaeridium (subsequently Baltisphaeridium) sexradiatum, according to Eisenack (1965c, p.261).  This combination was not validly published in Wright and Meyers (1981, p.28) since these authors did not fully reference the basionym.  The name Ovum hispidum subsp. polygonale was not validly published in Eisenack (1931) since the specific name Ovum hispidum was not validly published.  Age: Silurian (erratic).
