Grevillea dilatata is a species of plant in the protea family that is endemic to Australia. It is native to south-eastern South Australia, including Kangaroo Island as well as the Eyre and Yorke Peninsulas.
Grevillea dilatata is a shrub that grows up to 0.3–2 metres (0.98–6.56 ft) tall and up to 3 metres (9.8 ft) across. Leaves appear 'fan-shaped' with margins appearing more 'toothed' than lobed and noticeably pungent. The upper surface of the leaf is either glabrous or with sparse indumentum. The lower surface is always covered in subsericious (straight, silky) hairs. [1] [3]
This species was once considered part of Grevillea ilicifolia, where it was known as Grevillea ilicifolia var. dilatata. [4] A morphological study published in 2004 resulted in G. ilicifolia being separated into three species and four subspecies. [3] The specific epithet (dilatata) is a Latin word meaning "expanded" or "widened". In some publications, it is still referred to as Grevillea ilicifolia var. dilatata. [1]
This species can be found in mallee, heath and shrubland habitats in south-eastern South Australia, including the York and Eyre penninsulas and Kangaroo Island. [1]
Grevillea dilatata is listed as Vulnerable on the IUCN Red List of Threatened Species, as it has lost 30% of its habitat from the 1980s to now due to land clearing for agriculture. It is currently threatened by habitat loss and fragmentation for agriculture and competition with invasive weeds. The population ia likely to be currently stable and it appears to be locally common within its distribution. [1]
Grevillea banksii, commonly known as Banks' grevillea, Byfield waratah, red flowered silky oak and dwarf silky oak, and in Hawaii as kāhili flower, is a species of flowering plant in the family Proteaceae and is endemic to Queensland. It is an erect shrub or slender tree with divided leaves with four to twelve narrow lobes, and creamy white to bright scarlet and yellow flowers.
Banksia ilicifolia, commonly known as holly-leaved banksia, is a tree in the family Proteaceae. Endemic to southwest Western Australia, it belongs to Banksia subg. Isostylis, a subgenus of three closely related Banksia species with inflorescences that are dome-shaped heads rather than characteristic Banksia flower spikes. It is generally a tree up to 10 metres (33 ft) tall with a columnar or irregular habit. Both the scientific and common names arise from the similarity of its foliage to that of the English holly Ilex aquifolium; the glossy green leaves generally have very prickly serrated margins, although some plants lack toothed leaves. The inflorescences are initially yellow but become red-tinged with maturity; this acts as a signal to alert birds that the flowers have opened and nectar is available.
Grevillea juniperina, commonly known as juniper- or juniper-leaf grevillea or prickly spider-flower, is a plant of the family Proteaceae native to eastern New South Wales and southeastern Queensland in Australia. Scottish botanist Robert Brown described the species in 1810, and seven subspecies are recognised. One subspecies, G. j. juniperina, is restricted to Western Sydney and environs and is threatened by loss of habitat and housing development.
Actinostrobus arenarius is a species of conifer in the cypress family, Cupressaceae. Its common names include sandplain cypress, Bruce cypress, Bruce cypress-pine, and tamin. It is endemic to Western Australia.
Grevillea baueri, commonly known as Bauer's grevillea, is a species of flowering plant in the family Proteaceae and is endemic to the coastal ranges of south-eastern New South Wales. It is a low, spreading to erect shrub with mostly oblong to egg-shaped leaves with red to pink and cream-coloured or yellow flowers.
Grevillea caleyi, also known as Caley's grevillea, is a critically endangered species of flowering plant in the family Proteaceae and is endemic to a restricted area around the Terrey Hills and Belrose area in New South Wales. It is an open, spreading shrub, growing up to 4 m (13 ft) tall with deeply divided leaves with linear lobes, and fawn flowers with a maroon to red style.
Grevillea montis-cole, commonly known as Mount Cole grevillea, is a species of flowering plant in the family Proteaceae and is endemic to central-western Victoria, Australia. It is a shrub with divided leaves with 5 to 15 lobes, the end lobes more or less triangular to narrowly oblong and sharply-pointed, and clusters of greenish to fawn and dull purplish flowers.
Grevillea acropogon is a species of flowering plant in the family Proteaceae and is endemic to a restricted part of southwestern Western Australia. It is a prostrate to erect shrub with pinnatisect leaves with five to seven sharply-pointed lobes, and red flowers.
Grevillea ilicifolia, commonly known as holly grevillea or holly bush, is a species of flowering plant in the family Proteaceae and is endemic to southern continental Australia. It is a spreading to prostrate shrub with holly-like leaves with sharply-pointed triangular to egg-shaped teeth or lobes, and clusters of green to cream-coloured and mauve flowers with a pink to red style.
Grevillea angustiloba, commonly known as dissected holly-leaf grevillea, is a species of flowering plant in the family Proteaceae and is endemic to southern continental Australia. It is a prostrate, low-lying or erect shrub with deeply divided pinnate leaves and usually red, sometimes orange or pale yellow flowers.
Grevillea cyranostigma, commonly known as Carnarvon grevillea or green grevillea, is a species of flowering plant in the family Proteaceae and is endemic to the Carnarvon Range and adjacent areas of central Queensland. It is a spreading shrub with woolly-hairy to silky-hairy branchlets, narrowly oblong leaves, and pale green flowers.
Grevillea aspera, commonly known as the rough grevillea, is a species of flowering plant in the family Proteaceae and is endemic to Australia, occurring mainly in South Australia. It is low, spreading to erect shrub with oblong to egg-shaped leaves with the narrower end towards the base, and pinkish to red and cream-coloured, green, yellow or white flowers.
Grevillea scortechinii, commonly known as black grevillea, is a species of flowering plant in the family Proteaceae and is endemic to eastern Australia. It is a prostrate to sprawling shrub with serrated to pinnatifid leaves, the end lobes broadly triangular and often sharply-pointed, and clusters of brown flowers with a dark purplish-black style. There are two subspecies, subsp. scortechinii found in Queensland and subsp. sarmentosa, found in New South Wales.
Lomatia arborescens, commonly known as smooth lomatia or tree lomatia, is a shrub or small tree that grows at high altitudes, in and near rainforests. It is found north from the Barrington Tops area in eastern Australia.
Grevillea anethifolia, commonly known as spiny cream spider flower, is a species of flowering plant in the family Proteaceae and is endemic to continental Australia. It is an erect shrub with hairy branchlets, lobed leaves, the lobes sharply pointed, and white to pale yellow or cream-coloured flowers.
Grevillea brachystylis, also known as short-styled grevillea, is a species of flowering plant in the family Proteaceae and is endemic to the south-west of Western Australia. It is a low, spreading to erect shrub with linear to narrow egg-shaped leaves with the narrow end towards the base, and wheel-like clusters of hairy red flowers.
