area for insects attending to the stigma, which is located at the tip of the style. The smooth fleshy fruit, known as a drupe, is green and more or less round, measuring 1 cm (0.4 in) by 0.8 cm (0.3 in) in diameter. It contains two seeds, and has a spike at the end. The drupe is juicy but stringy when unripe, and the seeds and skin are inedible. Taxonomy and classification Persoonia levis was described and given the name Linkia levis by Antonio José Cavanilles in 1798. His description was based on plant material collected by Luis Née in the vicinity of Port Jackson (Sydney) in April 1793 during the Malaspina Expedition. The species was placed in the genus Persoonia by Karel Domin in 1921. The genus names Linkia and Persoonia had been coined in 1798, but the latter was officially conserved. The species name is the Latin adjective , meaning "smooth", and refers to the hairless foliage. Christiaan Hendrik Persoon coined the name Persoonia salicina for it in his 1805 work Synopsis Plantarum, and queried whether Cavanilles' Linkia levis was in fact P. lanceolata. Robert Brown used Persoon's name in his 1810 work Prodromus Florae Novae Hollandiae et Insulae Van Diemen, and echoed Persoon's thoughts on Cavanilles' original name and specimen. In the 1995 Flora of Australia revision of the genus, Peter John Weston reviewed the mounted material of Linkia levis, and found that Cavanilles had mounted material from both P. levis and P. lanceolata. He set one specimen of the three, which was clearly P. levis, as the lectotype, which aligned the material with the description. Common names include broad-leaved geebung, willow geebung and smooth geebung. The term geebung is derived from the Dharug language word geebung. Like most other members of the genus, Persoonia levis has seven chromosomes that are large compared to those of other Proteaceae. In 1870, George Bentham published the first infrageneric arrangement of Persoonia in Volume 5 of his landmark Flora Australiensis. He divided the genus into three sections, placing P. levis (which he called P. salicina) in P. sect. Amblyanthera. The 1995 Flora of Australia revision of the genus saw it classified in the Lanceolata group, a group of 58 closely related species with similar flowers but very different foliage. These species will often interbreed with each other where two members of the group occur, and hybrids with P. acerosa, P.
