Isopogon longifolius is a species of flowering plant in the family Proteaceae and is endemic to the southwest of Western Australia. It is a shrub with simple, linear, or deeply divided leaves and sessile, spherical heads of silky-hairy, yellow flowers and spherical to oval cone.
Isopogon longifolius is a shrub that typically grows to a height of up to 2.5 m (8 ft 2 in), its branchlets brownish to grey and hairy when young. The leaves are simple, linear to narrowly egg-shaped with the narrower end towards the base, sometimes deeply divided with two or three lobes, about 155 mm (6.1 in) long on a petiole about 30 mm (1.2 in) long. The flowers are borne in a spherical, sessile cluster up to about 25 mm (0.98 in) in diameter, each flower up to 15 mm (0.59 in) long, yellow and silky-hairy with a spindle-shaped pollen presenter up to 3.5 mm (0.14 in) long. Flowering occurs from November to January, and the fruit is a shaggy-hairy nut 3–4 mm (0.12–0.16 in) long, held in a more or less spherical to oval cone up to 26 mm (1.0 in) in diameter. [2] [3]
Isopogon longifolius was first formally described by botanist Robert Brown in Transactions of the Linnean Society of London in 1810. [4] [5]
In 1891, German botanist Otto Kuntze published Revisio generum plantarum , his response to what he perceived as a lack of method in existing nomenclatural practice. [6] Because Isopogon was based on Isopogon anemonifolius , [7] and that species had already been placed by Richard Salisbury in the segregate genus Atylus in 1807, [8] Kuntze revived the latter genus on the grounds of priority, and made the new combination Atylus longifolius for this species. [9] However, Kuntze's revisionary program was not accepted by the majority of botanists. [6] Ultimately, the genus Isopogon was nomenclaturally conserved over Atylus by the International Botanical Congress of 1905. [10]
This species often grows on sandstone hills in heath or shrubland and is found on the Stirling Range, the Porongurup Range, near Albany, Walpole and Cranbrook and on the coast towards Bremer Bay. [2] [3]
Isopogon longifolius is listed as "not threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions. [3]
Banksia grandis, commonly known as bull banksia or giant banksia, is a species of common and distinctive tree in the south-west of Western Australia. The Noongar peoples know the tree as beera, biara, boongura, gwangia, pira or peera. It has a fire-resistant main stem with thick bark, pinnatisect leaves with triangular side-lobes, pale yellow flowers and elliptical follicles in a large cone.

It has greyish brown bark, hairy stems, deeply serrated leaves with triangular lobes and lemon-yellow flowers in an oval flower spike that grows on the end of branches.
Banksia candolleana, commonly known as the propeller banksia, is a species of shrub that is endemic to Western Australia. It has shiny green, deeply serrated leaves with triangular lobes and spikes of golden yellow flowers on short side branches.
Banksia littoralis, commonly known as the swamp banksia, swamp oak, river banksia or seaside banksia and the western swamp banksia, is a species of tree that is endemic to the south-west of Western Australia. The Noongar peoples know the plant as pungura, boongura or gwangia. It has rough, crumbly bark, linear, more or less serrated leaves arranged in whorls, yellow flowers and up to two hundred follicles in each head.
Banksia meisneri, commonly known as Meisner's banksia, is a shrub that is endemic to a small area in the south-west of Western Australia. It has crowded, more or less linear leaves and in winter and spring, spikes of golden brown flowers followed by furry fruit which usually only open after fire.
Isopogon anemonifolius, commonly known as broad-leaved drumsticks, is a shrub of the family Proteaceae that is native only to eastern New South Wales in Australia. It occurs naturally in woodland, open forest, and heathland on sandstone soils. I. anemonifolius usually ranges between one and two metres in height, and is generally smaller in exposed heathland. Its leaves are divided and narrow, though broader than those of the related Isopogon anethifolius, and have a purplish tinge during the cooler months. The yellow flowers appear during late spring or early summer and are displayed prominently. They are followed by round grey cones, which give the plant its common name drumsticks. The small hairy seeds are found in the old flower parts.
Isopogon dawsonii, commonly known as the Nepean conebush, is a shrub of the family Proteaceae and is endemic eastern to New South Wales. It has pinnate leaves with narrow segments and spherical heads of creamy yellow to greyish white flowers.
Isopogon cuneatus, commonly known as coneflower, is a species of plant in the family Proteaceae and is endemic to the south-west of Western Australia. It is a shrub with oblong to egg-shaped leaves with the narrower end towards the base, and flattened-spherical heads of glabrous pale to purplish pink flowers.
Isopogon anethifolius, commonly known as narrow-leaf drumsticks or narrow-leafed drumsticks, is a shrub in the family Proteaceae. The species is found only in coastal areas near Sydney in New South Wales, and to the immediate west. It occurs naturally in woodland, open forest and heathland on sandstone soils. An upright shrub, it can reach to 3 m (9.8 ft) in height, with terete leaves that are divided and narrow. The yellow flowers appear in the Spring, from September to December, and are prominently displayed. They are followed by round grey cones, which give the plant its common name of drumsticks. The small hairy seeds are found in the old flower parts.
Banksia stuposa is a species of shrub that is endemic to the southwest of Western Australia. It has hairy stems, broadly linear pinnatifid leaves, golden yellow and white flowers in heads of one hundred or more, and hairy, egg-shaped follicles.
Isopogon ceratophyllus, commonly known as the horny cone-bush or wild Irishman, is a plant of the family Proteaceae that is endemic to the coast in Victoria, South Australia and on the Furneaux Group of islands in Tasmania. It is a small woody shrub that grows to 100 cm high with prickly foliage. It is extremely sensitive to dieback from the pathogen Phytophthora cinnamomi
Telopea truncata, commonly known as the Tasmanian waratah, is a plant in the family Proteaceae. It is endemic to Tasmania where it is found on moist acidic soils at altitudes of 600 to 1200 m (2000–4000 ft). Telopea truncata is a component of alpine eucalypt forest, rainforest and scrub communities. It grows as a multistemmed shrub to a height of 3 metres (10 ft), or occasionally as a small tree to 10 m (35 ft) high, with red flower heads, known as inflorescences, appearing over the Tasmanian summer and bearing 10 to 35 individual flowers. Yellow-flowered forms are occasionally seen, but do not form a population distinct from the rest of the species.
