Persoonia linearis, commonly known as the narrow-leaved geebung, is a
Found in dry sclerophyll forest on sandstone-based nutrient-deficient soils, P. linearis is adapted to a fire-prone environment; the plants resprout epicormic buds from beneath their thick bark after bushfires. The fruit are consumed by vertebrates such as kangaroo, possums and currawongs. As with other members of the genus, P. linearis is rare in cultivation as it is very hard to propagate by seed or by cuttings, but once propagated, it adapts readily, preferring acidic soils with good drainage and at least a partly sunny aspect.
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.[2] He had been given a plant in flower by J. Robertson of Stockwell, who had grown it from seed in 1794.[3] The species name is the Latin linearis "linear", referring to the shape of the leaves.[4]
Meanwhile, German botanist
In 1870,
The genus was reviewed by Peter Weston for the Flora of Australia treatment in 1995, and P. linearis was placed in the Lanceolata group,[12] a group of 54 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,[14] and hybrids with P. chamaepeuce, P. conjuncta, P. curvifolia, P. lanceolata, P. media, five subspecies of P. mollis, P. myrtilloides subsp. cunninghamii, P. oleoides, P. pinifolia and P. sericea have been recorded.[12] Robert Brown initially described the hybrid with P. levis as a species "Persoonia lucida",[4] which is now known as Persoonia × lucida,[15] and has been recorded from the southeast forests of the New South Wales south coast.[16]
Bentham wrote in 1870 that the name geebung, derived from the
Description
Persoonia linearis grows as a tall shrub to small tree, occasionally reaching 5 m (16 ft) in height but more commonly around 2–3 m (6.6–9.8 ft) tall.[19] The flaky soft bark is dark grey on the surface,[12] while deeper layers are reddish. Within the bark are epicormic buds, which sprout new growth after bushfire.[14] The new growth is hairy. The leaves are more or less linear in shape, measuring 2 to 9 cm (0.79 to 3.54 in) in length and 0.1 to 0.7 cm (0.039 to 0.276 in) wide, with slightly down-rolled margins.[12]

Ecology
Persoonia linearis is one of several species of Persoonia that regenerate by resprouting from trunks or stems greater than 2 cm (0.79 in) thick after bushfire,[20] an adaptation to the fire-prone habitat where it grows.[14] However, only larger trunks of 12–16 cm (4.7–6.3 in) diameter might survive to reshoot after very hot fires.[25] The thick papery bark shields and insulates the underlying epicormic buds from the flames.[14] The plant can reshoot from the base, but generally only if the stem or trunk is killed.[25]
Colletid bees of the genus Leioproctus, subgenus Cladocerapis exclusively forage on and pollinate flowers of many species of Persoonia. Bees of subgenus Filiglossa in the same genus, which also specialise in feeding on Persoonia flowers, do not appear to be effective pollinators.[14] Weighing 1900 mg (0.07 oz), the fruit are adapted to be eaten by vertebrates, such as kangaroos, possums and currawongs and other large birds.[20] Seeds have been recorded in the faeces of the brush-tailed rock-wallaby (Petrogale penicillata).[26]

A compound with antimicrobial activity was isolated from the ripening drupes of a hybrid of Persoonia linearis and P. pinifolia growing in the Australian National Botanic Gardens in 1994, and identified as 4-hydroxyphenyl 6-O-[(3R)-3,4-dihydroxy-2-methylenebutanoyl]-β-D-glucopyranoside.[28]
