Word History

Etymology

New Latin Mitragyna, genus of plants from which the substance is obtained (from Greek mítra "woman's circular headdress" + New Latin -gyna, -gynē "female reproductive organ," borrowed from Greek gynḗ "woman") + -ine entry 2 — more at miter entry 1, queen entry 1

Note: The name mitragynine was introduced by the British biochemist Ellen Field (later Stedman, 1883-1962) in "Mitragynine and Mitraversine, Two New Alkaloids from Species of Mitragyne [sic]," Journal of the Chemical Society, Transactions, vol. 119 (1921), pp. 887-91. The genus name Mitragyna was introduced by the Dutch botanist Pieter Willem Korthals (1807-92) in Observationes de Naucleis Indicis (Bonn, 1839), p. 19. The name apparently alludes to the shape of the stigma, described by Korthals as resembling a mitra ("Stigma mitraforme"). Korthals presumably had in mind the circular headband worn by Greek women and associated with the goddess Demeter, though the word has other meanings (see miter entry 1).
