Persoonia micranthera, commonly known as the small-flowered snottygobble, is an endangered prostrate shrub with yellow flowers and thin bark. It grows only on two peaks, Bluff Knoll and Isongerup Peak, in the eastern section of the Stirling Range, Western Australia. A slow-growing plant, it takes more than six years to produce flowers and seed.
An endangered species is a species which has been categorized as very likely to become extinct. Endangered (EN), as categorized by the International Union for Conservation of Nature (IUCN) Red List, is the second most severe conservation status for wild populations in the IUCN's schema after Critically Endangered (CR).
A prostrate shrub is a woody plant, most of the branches of which lie upon or just above the ground, rather than being held erect as are the branches of most trees and shrubs.
Bluff Knoll is the highest peak of the Stirling Range in the Great Southern region of Western Australia (WA). It is 1,099 metres (3,606 ft) above sea level, and is one of only a few places to experience regular snowfalls in Western Australia, with some snow reported in most years. The last heavy snowfall was on 6 October 1992 when 20 centimetres of snow was recorded and light snow was seen at the base, 450 metres (1,480 ft). Snow fell on three occasions in 2016 after only falling once in 2015. Although Bluff Knoll is sometimes claimed to be the highest point in Western Australia, the highest peak is actually Mount Meharry in Karijini National Park in the Hamersley Range, which is 1,249 metres (4,098 ft) above sea level.
Prior to 1980, Persoonia micranthera was also present on Coyanerup Peak, but none were found there in 1990, and that population is now believed extinct. In April 1991 an intense bushfire burnt all known populations except for three adult plants on Isongerup Peak. A 1997 survey noted three adults and 150 seedlings on Isongerup Peak, but a 1999 survey of Bluff Knoll found no adults and only two seedlings there.
In biology, extinction is the termination of an organism or of a group of organisms (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" after a period of apparent absence.
Persoonia is a genus of about one hundred species of shrubs and small trees in the subfamily Persoonioideae in the large and diverse plant family Proteaceae. In the eastern states of Australia, they are commonly known as geebungs, while in Western Australia and South Australia they go by the common name snottygobbles. While their flowers are small and not prominent, persoonias are best known in the Australian bush for the striking bright green foliage of many species.
Banksia oligantha, commonly known as Wagin banksia, is an endangered species in the plant family Proteaceae endemic to south west Western Australia. It belongs to Banksia subg. Isostylis, a subgenus of three closely related Banksia species with dome-shaped heads as inflorescences, rather than characteristic Banksia flower spikes. A shrub or small tree up to 4 m (13 ft) high, it has prickly foliage and pink and cream flowerheads which appear in late Spring.
Banksia verticillata, commonly known as granite banksia or Albany banksia, is a species of shrub or (rarely) tree of the genus Banksia in the family Proteaceae. It is native to the southwest of Western Australia and can reach up to 3 m (10 ft) in height. It can grow taller to 5 m (16 ft) in sheltered areas, and much smaller in more exposed areas. This species has elliptic green leaves and large, bright golden yellow inflorescences or flower spikes, appearing in summer and autumn. The New Holland honeyeater is the most prominent pollinator, although several other species of honeyeater, as well as bees, visit the flower spikes.
Persoonia longifolia, the upright snottygobble, also known as the long-leaf persoonia or just snottygobble, is a species of tall shrub or small tree in the plant genus Persoonia, reaching 1 to 5 metres (3–17 ft) in height. It is found in the Jarrah forests of southwest Western Australia. This species is characterised by its long narrow dark green leaves, dark yellow to orange flowers and distinctive flaky dark red bark.
Banksia montana, commonly known as the Stirling Range dryandra, is a shrub of the family Proteaceae endemic to Western Australia, where it grows only in the Stirling Range. It was known as Dryandra montana until 2007.
Persoonia levis, commonly known as the broad-leaved geebung, is a shrub native to New South Wales and Victoria in eastern Australia. It reaches 5 m (16 ft) in height and has dark grey papery bark and bright green asymmetrical sickle-shaped leaves up to 14 cm (5.5 in) long and 8 cm (3.2 in) wide. The small yellow flowers appear in summer and autumn, followed by small green fleshy fruit, which are classified as drupes. Within the genus Persoonia, it is a member of the Lanceolata group of 58 closely related species. P. levis interbreeds with several other species where they grow together.
Persoonia lanceolata, commonly known as lance-leaf geebung, is a shrub native to New South Wales in eastern Australia. It reaches 3 m (9.8 ft) in height and has smooth grey bark and bright green foliage. Its small yellow flowers grow on racemes and appear in the austral summer and autumn, followed by green fleshy fruits which ripen the following spring. Within the genus Persoonia, P. lanceolata belongs to the lanceolata group of 58 closely related species. It interbreeds with several other species found in its range.
Persoonia laurina, commonly known as the laurel-leaved or laurel geebung, is a shrub of the family Proteaceae native to central New South Wales in eastern Australia. Found in sclerophyll forest, it grows to a height of 2 metres. The yellow flowers appear in late spring.
Persoonia myrtilloides, commonly known as myrtle geebung, is a shrub species that is endemic to New South Wales in Australia. It grows to between 0.5 and 2.5 metres in height and has leaves that are between 12 and 50 millimetres long and 4 to 30 millimetres wide. Yellow flowers appear between December and April in the species native range.
Persoonia hirsuta, commonly known as the hairy persoonia or hairy geebung, is a shrub native to New South Wales in eastern Australia.
Persoonia marginata, commonly known as the Clandulla geebung, is a plant in the family Proteaceae and is endemic to New South Wales. It is low, spreading shrub with elliptic to egg-shaped leaves and small groups of cylindrical yellow flowers.
Persoonia gunnii, commonly known as the mountain geebung, is a slow-growing shrub endemic to wet forests and subalpine shrubberies in Tasmania. It forms a bush ranging from 0.6 to 3 m in height with short, up-curved leaves and scented cream-yellow flowers in summer giving way to small dark purple fruit. It is a common shrub in subalpine areas of the state and is occasionally confused with P. muelleri.
Persoonia muelleri, commonly known as Mueller’s geebung, is a shrub endemic to Tasmania. It forms a shrub in open areas of wet forests in the west and northeast of the state. It is occasionally confused with P. gunnii though it has larger flowers and longer, straighter leaves.
