Gerardia

== Translingual == === Etymology === From English Gerard (surname) +‎ Latin -ia. The botanical genera are named after English herbalist John Gerard (1545–1612). === Proper noun === Gerardia f (obsolete) Several taxonomic genera: (botany) [1753-1836] A taxonomic genus within the family Acanthaceae – a type of purple flower, see Stenandrium. (botany) [1836-1956] A taxonomic genus within the family Orobanchaceae – a type of purple flower, see Agalinis. (zoology) [1864] A taxonomic genus within the family Parazoanthidae – a type of hexacoral, see Savalia. (zoology) [1954-2015] A taxonomic genus within the family Tenebrionidae – a type of darkling beetle, see Piccula. ==== Usage notes ==== In botany, Linnaeus' original 1753 description of Gerardia included one specimen of Stenandrium and four of Agalinis; this error was first established in 1810, but disagreement over the rules of nomenclature resulted in the name Gerardia being officially rejected for either taxon in 1956 and 1959, respectively. In zoology, Gerardia was accepted as the name of Piccula for over 60 years before taxonomists realized the name hadn't been available, already discarded as a superfluous name of Savalia almost a century earlier. === References === Gerardia on Wikipedia.Wikipedia Gerardia on Wikispecies.Wikispecies
