Abstract
Summary: A second, post‐Linnean, edition of Hill, “A history of plants”, is described.For purposes of botanical nomenclature Wiggers, not G. H. Weber, should be considered as the author of the “Flora holsatica”.The names published as “species naturales” by Necker are to be considered as validly published generic names.A lectotype species is chosen for the genus Conicephala Hill and the genus Conocephalum Wiggers, a substitute name for the former. The common lectotype species of these genera, and the species Marchantia conica L., are in turn provided with a lectotype, the same lectotype serving for both.Conocephalum Wiggers is proposed for conservation against Conicephala Hill.
