Occurrence data from AVH |
Acacia havilandiorum, also known as Haviland's wattle or needle wattle, [2] is a shrub of the genus Acacia and the subgenus Plurinerves. It is native to areas in South Australia, New South Wales and Victoria.
The bushy shrub or small typically grows to a height of 1.5 to 4 metres (5 to 13 ft) [3] and has glabrous and terete branchlets. Like most species of Acacia it has phyllodes rather than true leaves. The grey to green, inclined to ascending and straight or slightly incurved, rigid phyllodes are 3 to 9 cm (1.2 to 3.5 in) in length and 0.8 to 1.5 mm (0.031 to 0.059 in) wide and are quite brittle and tend to break easily. [2] It blooms between July and October producing simple inflorescences which occur in group of one to three in the axils and have spherical flower-heads with a diameter of 3 to 7.5 mm (0.12 to 0.30 in) and contain 20 to 30 bright yellow coloured flowers. Following flowering it produces glabrous and firmly papery seed pods which are straight to curved and raised over each seed and slightly constricted between them and have a length of 3 to 9 cm (1.2 to 3.5 in) and a width of 2 to 3 mm (0.079 to 0.118 in). [4]
The species was first described by Joseph Maiden in 1920 as Acacia havilandi, [5] [6] despite the specific epithet honouring both Edwin Haviland and his son, [4] who " specialised in the fertilisation of Australian plants and (have) also worked at taxonomy and other branches of botany" [5] [6] The epithet was changed to a genitive plural (havilandiorum) to accord with ICN Art. 60.8 (Shenzhen Code, 2018). [5]
The plant has a scattered and discontinuous distribution from as far west as the Eyre Peninsula in South Australia where it is common, to further north in the Flinders Range through to Griffith and Cobar but the range extends as far as Gilgandra in the east. It is only known around Horsham in the north west region of Victoria. [2] In New South Wales the plant is mostly found in the Pilliga Scrub between Gilgandra and Milgee as a part of mallee and box woodland communities. [4]
Acacia longifolia is a species of Acacia native to southeastern Australia, from the extreme southeast of Queensland, eastern New South Wales, eastern and southern Victoria, southeastern South Australia, and Tasmania. Common names for it include long-leaved wattle, acacia trinervis, aroma doble, golden wattle, coast wattle, sallow wattle and Sydney golden wattle. It is not listed as being a threatened species, and is considered invasive in Portugal, New Zealand and South Africa. In the southern region of Western Australia, it has become naturalised and has been classed as a weed by out-competing indigenous species. It is a tree that grows very quickly reaching 7–10 m in five to six years.
Acacia myrtifolia, known colloquially as myrtle wattle, red stem wattle or red-stemmed wattle, is a species of Acacia native to coastal areas of southern and eastern Australia.
Acacia bakeri, known as the marblewood, white marblewood, Baker's wattle or scrub wattle, is one of the largest of all acacias, growing to 40 m (130 ft) tall. It is a long-lived climax rainforest tree from eastern Australia. Unlike most acacias, fire is not required for seed germination. This tree is considered vulnerable to extinction. Its former habitat is lowland sub tropical rainforest which has been mostly cleared in the 19th and 20th centuries.
Acacia bynoeana, known colloquially as Bynoe's wattle or tiny wattle, is a species of Acacia native to eastern Australia. It is listed as endangered in New South Wales and as vulnerable according to the Environment Protection and Biodiversity Conservation Act 1999.
Acacia linifolia, known colloquially as white wattle, or flax wattle, is a species of Acacia native to eastern Australia.
Acacia burkittii is a species of wattle endemic to Western Australia, South Australia and western New South Wales, where it is found in arid zones, and is a perennial shrub in the family Fabaceae. Common names for it include Burkitt's wattle, fine leaf jam, gunderbluey, pin bush and sandhill wattle. It has also been introduced into India. Previously this species was referred to as Acacia acuminata subsp. burkittii, but is now considered to be a separate species. Grows in mallee, eucalypt and mulga woodland or shrubland, often on sandhills.
Acacia jibberdingensis, also known as Jibberding wattle or willow-leafed wattle, is a shrub or tree belonging to the genus Acacia and the subgenus Juliflorae that is endemic to Western Australia.
