Persoonia linearis [SEP] Taxonomy
English botanist and artist Henry Cranke Andrews described "Persoonia linearis" in 1799, in the second volume of his "Botanists Repository, Comprising Colour'd Engravings of New and Rare Plants". He had been given a plant in flower by J. Robertson of Stockwell, who had grown it from seed in 1794. The species name is the Latin "linearis" "linear", referring to the shape of the leaves. Meanwhile, German botanist Karl Friedrich von Gaertner had coined the name "Pentadactylon angustifolium" in 1807 from a specimen in the collection of Joseph Banks to describe what turned out to be the same species. The genus name derived from the Greek "penta-" "five" and "dactyl" "fingers", and refers to the five-lobed cotyledons.
