Veryhachium polygonale Appendix A

"polygonale" (Eisenack, 1931, p.113, pl.4, figs.16-20; pl.5, fig.18 ex Eisenack, 1938a, p.12) Eisenack, 1963b, p.209.  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.  Combination not validly published: basionym not fully referenced.  NOW Polygonium polygonale (Appendix A).  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), fifthly Goniosphaeridium polygonale (Appendix A), sixthly (and now) Polygonium polygonale (Appendix A).  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 also not validly published in Deflandre and Deflandre-Rigaud (1964, fiche 2061), since these authors did not fully reference the basionym.  Age: Silurian (erratic).
