Botanical history and taxonomy

On 8 July 1805,
Jacques Labillardière Jacques-Julien Houtou de Labillardière (28 October 1755 – 8 January 1834) was a French biologist noted for his descriptions of the flora of Australia. Labillardière was a member of a voyage in search of the La Pérouse expedition. He pub ...

Polypodiaceae Polypodiaceae is a family of ferns. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), the family includes around 65 genera and an estimated 1,650 species and is placed in the order Polypodiales, suborder Polypodiineae. A broade ...

, so the suffix should not be changed with different gender generic names. Later,
Ferdinand von Mueller Baron Sir Ferdinand Jacob Heinrich von Mueller, (german: Müller; 30 June 1825 – 10 October 1896) was a German-Australian physician, geographer, and most notably, a botanist. He was appointed government botanist for the then colony of Vic ...
insisted on using the illegitimate genus ''Candollea'' and shifted the ''Stylidium'' species back in the late 19th century. Those moves, however, were not widely adopted. In 2001, Raulings and Ladiges recognized several synonyms.
