First published in: Enum. Pl. Austral. Occ.: 3. (1930).
Etymology: Honoring Anselme Riedlé (1775–1801), former head gardener at the Jardin des Plantes in Paris and friend of the great French explorer Nicolas Baudin, who he accompanied on a scientific expedition (1800–1804) to chart the coast of New Holland (Australia) and collected the type of this species. (Hill & Osborne 2001, Jones 2002) [source]
Nomenclature notes: Gardner published the combination as Macrozamia reidlei. Australian Plant Name Index notes that Gardner did not cite a basionym directly, but included Macrozamia fraseri Miq. in synonymy. Gardner's preface explains that bracketed synonyms refer to names as used in Bentham's Flora Australiensis, where Cycas riedlei is treated under M. fraseri. The combination is therefore based by indirect reference on Cycas riedlei Fisch. ex Gaudich.
The basionym Cycas riedlei Fisch. ex Gaudich. was conserved against the earlier homonym C. riedlei Dum. Cours. following Calonje & Clugston's 2022 proposal (Taxon 71: 1113–1115). The Nomenclature Committee for Vascular Plants recommended conservation 16–1 in 2024 (Report 75), and the General Committee accepted it 25–2 later that year (Report 31). This preserves the basionym and the familiar name and authorship of Macrozamia riedlei; full typification details are given on the basionym record.

Location Privacy Notice: This map is provided to show a rough estimate of the distribution of this species based on georeferenced localities on the WLoC database. The points may not be comprehensive of the species distribution and may contain errors. To protect the precise locations of populations of this highly threatened plant group, coordinates displayed on this map have been denatured to 0.1 degree precision (approximately 11 km accuracy). Map zoom levels are also limited for conservation purposes.
