SummaryBotanists have used Styrax in all genders. The etymology of Styrax, the problems with its classical and dictionary genders, and arguments for and against the various botanical genders are evaluated. We find that the Linnaean adoption of neuter was a simple error, the use of feminine has only theoretical justification and that masculine gender best fits the wording of our present (Botanical) Code for Styrax, as well as Panax.
