(2918) Proposal to conserve the name Cycas riedlei Fisch. ex Gaudich. (Macrozamia riedlei) against C. riedlei Dum. Cours. (Cycadaceae)

The name Cycas riedlei was reportedly coined by German botanist Friedrich Ernst Ludwig von Fischer (1782–1854), who served as the Director of the gardens of the Gorenki estate near Moscow, Russia and listed the plant, without any description, as “Cycas? Riedlei H. P.” (Fischer, Cat. Jard. Gorenki: 7. 1812). The acronym “H. P.” refers to “Hortus Parisiensis”, indicating that the relevant plant was obtained from the “Jardin des Plantes”, the botanical garden of the National Museum of Natural History in Paris. German agrostologist Ernst Gottlieb von Steudel (1783–1856) later listed the name, without description, as “Cycas Ridlei. Fisch. H. par.” (Steudel, Nomencl. Bot. 1: 247. 1821), ascribing it to Fischer and indicating the plant was sourced from the Hortus Parisiensis.
