| Isopogon panduratus | |
Isopogon panduratus is a plant in the family Proteaceae and is endemic to the southwest of Western Australia. It is a spreading shrub with narrow egg-shaped leaves and spherical heads of pale pink flowers.
Isopogon panduratus is a shrub that typically grows to about 2 m (6 ft 7 in) high and 1.5 m (4 ft 11 in) wide with smooth brownish branchlets. The leaves are narrow egg-shaped with the narrower end towards the base, 35–125 mm (1.4–4.9 in) long and 3–19 mm (0.12–0.75 in) wide, tapering to a petiole that expands towards its base. The flowers are arranged in spherical, sessile heads about mostly forty to seventy pale pink flowers, the heads 18–30 mm (0.71–1.18 in) in diameter, the heads with three to five whorls of involucral bracts at the base. Flowering mainly occurs from June to August or August to October, depending on subspecies. The fruit is a hairy nut about 3.5 mm (0.14 in) long, fused in a spherical to flattened spherical head 9–16 mm (0.35–0.63 in) long and 10–18 mm (0.39–0.71 in) wide. [2]
Isopogon panduratus was first formally described in 2010 by Michael Clyde Hislop and Barbara Lynette Rye from specimens collected by Hislop in Tathra National Park in 2000. [2] [3] The specific epithet (panduratus) is a reference to the shape of the inner involucral bracts that of a pandura. [2]
Hislop and Rye described two subspecies of I. panduratus and the names are accepted by the Australian Plant Census:
Subspecies palustris grows in heath on the coastal plain between Cervantes and near Cataby and subspecies panduratus is found in heath, sometimes Banksia woodland from near Eneabba to Watheroo National Park. [2]
Isopogon, commonly known as conesticks, conebushes or coneflowers, is a genus of about forty species of flowering plants in the family Proteaceae, and are endemic to Australia. They are shrubs with rigid leaves, bisexual flowers in a dense spike or "cone" and the fruit is a small, hairy nut.
Banksia conferta, commonly known as the glasshouse banksia, is a species of shrub that is endemic to eastern Australia. It has rough, bark on the trunk, elliptic to egg-shaped leaves arranged in whorls, crowded yellow flowers in a cylindrical spike later forming a relatively large number of follicles.
Banksia penicillata is a species of shrub that is endemic to a restricted area of New South Wales. It has smooth bark, serrated, elliptic to egg-shaped leaves, green to bluish flower buds, later yellow flowers in a cylindrical spike, and later still, up to one hundred narrow elliptical follicles in each spike, surrounded by the remains of the flowers.
Banksia drummondii, commonly known as Drummond's dryandra, is a species of shrub that is endemic to Western Australia. It has pinnatifid to pinnatisect leaves, heads of up to one hundred cream-coloured, red and yellow flowers and glabrous fruit.
Banksia rufa is a species of prostrate shrub that is endemic to the south-west of Western Australia. It has broadly linear, pinnatifid or pinnatipartite leaves with between five and twenty lobes on each side, yellow, orange or brownish flowers in heads of forty or more, and glabrous, egg-shaped follicles.
Banksia hirta is a species of shrub that is endemic to Western Australia. It has hairy stems, deeply serrated leaves, pale yellow flowers in heads of about one hundred and shining follicles. It is restricted to the Stirling Range National Park.
Banksia ionthocarpa is a species of shrub that is endemic to Western Australia. It has short, hairy, prostrate stems, pinnatifid leaves, pinkish purple to orange flower in heads of between forty and sixty at the base of leaves, and egg-shaped follicles with a distinctive tuft of hairs on the end.
Banksia dallanneyi, commonly known as couch honeypot, is a species of prostrate shrub that is endemic to Western Australia. It only has a short above-ground stem, pinnatipartite or pinnatisect leaves, between thirty and seventy variously coloured flowers and glabrous, egg-shaped fruit.
Banksia prolata is a species of bushy shrub that is endemic to Western Australia. It has linear, serrated or pinnatifid leaves, yellow flowers in heads of between 150 and 250, and egg-shaped follicles.
Banksia nivea, commonly known as honeypot dryandra, is a species of rounded shrub that is endemic to Western Australia. The Noongar peoples know the plant as bulgalla. It has linear, pinnatipartite leaves with triangular lobes, heads of cream-coloured and orange or red flowers and glabrous, egg-shaped follicles.
Banksia plumosa is a species of shrub that is endemic to Western Australia. It has hairy stems, broadly linear pinnatifid to pinnatipartite leaves with triangular lobes, creamy-yellow flowers in heads of up to eighty, and egg-shaped follicles.
Banksia pteridifolia, commonly known as tangled honeypot, is a species of shrub that is endemic to the southwest of Western Australia. It has short, underground stems, deeply pinnatipartite leaves with sharply-pointed, linear lobes on the sides, creamy white or yellow flowers in heads of about one hundred and later up to five follicles in each head.
Banksia serratuloides is a species of small shrub that is endemic to Western Australia. It has linear, pinnatipartite leaves, yellow and pink flowers in heads of about forty and hairy, wrinkled follicles.
Banksia splendida, commonly known as shaggy dryandra, is a species of shrub that is endemic to the southwest of Western Australia. It has sharply-pointed linear leaves that are woolly on the lower surface, cream-coloured and maroon or yellow flowers in heads of between 65 and 115, and later up to eight egg-shaped follicles in each head.
Banksia squarrosa, commonly known as pingle, is a species of prickly shrub that is endemic to Western Australia. It has linear to narrow lance-shaped leaves with up to ten sharply-pointed teeth on each side, yellow flowers in heads of about sixty and later, up to seven oblong to egg-shaped follicles in each head.
Isopogon adenanthoides, commonly known as the spider coneflower, is a plant in the family Proteaceae and is endemic to the southwest of Western Australia. It is an erect shrub with sharply-pointed, trifid leaves and spherical heads of pink flowers.
Isopogon pruinosus is a shrub in the family Proteaceae that is endemic to southwestern Western Australia. There are two accepted subspecies:
Isopogon gardneri is a plant in the family Proteaceae and is endemic to the southwest of Western Australia. It is a dense, prickly shrub with sharply-pointed, interlocking leaves and hairy, pale pink or yellow flowers.
Isopogon heterophyllus is a plant in the family Proteaceae and is endemic to the southwest of Western Australia. It is a shrub with simple or pinnate, cylindrical leaves and hairy, usually pink flowers.
Isopogon robustus is a plant in the family Proteaceae and is endemic to a restricted area in the southwest of Western Australia. It is a shrub with cylindrical leaves and oval heads of pink flowers.
