Description

Acacia obtusifolia is an upright or spreading perennial tree which grows from 1.5m to 8m in height and it is native to Australia. It is closely related to Acacia longifolia . Acacia obtusifolia can be distinguished by it having phyllode margins which are resinous, it usually blooms later in the year and it has paler flowers than Acacia longifolia. [2] It flowers usually from December through February. Some populations of Acacia obtusifolia can survive winters to −6 °C and possibly a light snow, however plants from populations in areas that are frost free such as the coastal ranges of Northern NSW are susceptible to cold and will be killed by frosts lower than −3 °C. These populations avoid the valley floors and occur mainly on sandstone ridges well above the frost line.

Phytochemicals

Teracacidin, a flavan-3,4-diol, can be isolated from A. obtusifolia heartwood. [3]

No formal scientific publishing of phytochemistry, several chromatographs show 0.3% alkaloid consisting 2:1 N-Methyltryptamine, dimethyltryptamine, plus trace betacarbolines, [4] another found gramine. It is highly variable in composition, sometimes devoid of tryptamines. Also findings of 5-MeO-DMT, DMT and bufotenine. [5] Some internet sources claim a 0.45% average dimethyltryptamine in the bark and 0.3% in the dried young leaves. Similarly, late 90s internet researchers have figures ranging from 0.4% to 0.5% in the dried material, noting there to be some variability. [6]

<i>Acacia sensu lato</i> Genus of legumes

Acacia s.l., known commonly as mimosa, acacia, thorntree or wattle, is a polyphyletic genus of shrubs and trees belonging to the subfamily Mimosoideae of the family Fabaceae. It was described by the Swedish botanist Carl Linnaeus in 1773 based on the African species Acacia nilotica. Many non-Australian species tend to be thorny, whereas the majority of Australian acacias are not. All species are pod-bearing, with sap and leaves often bearing large amounts of tannins and condensed tannins that historically found use as pharmaceuticals and preservatives.

<i>N</i>,<i>N</i>-Dimethyltryptamine Chemical compound

N,N-Dimethyltryptamine is a substituted tryptamine that occurs in many plants and animals, including humans, and which is both a derivative and a structural analog of tryptamine. DMT is used as a psychedelic drug and prepared by various cultures for ritual purposes as an entheogen.

<i>Acacia baileyana</i> Species of shrub

Acacia baileyana or Cootamundra wattle is a shrub or tree in the flowering plant family Fabaceae. The scientific name of the species honours the botanist Frederick Manson Bailey. It is indigenous to a very small area in southern inland New South Wales, comprising Temora, Cootamundra, Stockinbingal and Bethungra districts. However, it has been widely planted in other Australian states and territories. In many areas of Victoria, it has become naturalised and is regarded as a weed, outcompeting indigenous Victorian species.

<i>Acacia acuminata</i> Species of legume

Acacia acuminata, known as mangart and jam, is a tree in the family Fabaceae. Endemic to Western Australia, it occurs throughout the south west of the State. It is common in the Wheatbelt, and also extends into the semi-arid interior.

<i>Acacia maidenii</i> Species of legume

Acacia maidenii, also known as Maiden's wattle, is a tree native to Australia. It has been introduced into India, and Argentina, and it grows on plantations in South Africa.

<i>N</i>-Methyltryptamine Chemical compound

N-Methyltryptamine (NMT) is a member of the substituted tryptamine chemical class and a natural product which is biosynthesized in the human body from tryptamine by certain N-methyltransferase enzymes, such as indolethylamine N-methyltransferase. It is a common component in human urine. NMT is an alkaloid derived from L-tryptophan that has been found in the bark, shoots and leaves of several plant genera, including Virola, Acacia, Mimosa, and Desmanthus—often together with the related compounds N,N-dimethyltryptamine (DMT) and 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT).

<i>Acacia phlebophylla</i> Species of legume

Acacia phlebophylla, a type of acacia also known by the names Buffalo sallow wattle and Mount Buffalo wattle, is a straggling shrub to small, twisted tree reaching up to 5 m in height. It is a close relative of Acacia alpina. It has large, elliptic, flat, commonly asymmetrical phyllodes 4–14 cm long, 1.5–6 cm wide, with coarse veins, a leathery feel, prominent nerves and reticulated veins. Deep yellow rod-like flowers appear in spring, widely scattered on spikes 4–7 cm long, followed by 7–10 cm long legumes in November–March, narrow, straight or slightly curved, releasing 5–10 elliptical seeds, 5–7.5 mm long. Solitary or twinned spikes, to 6 cm long. Only known from the high altitude granite slopes of Mount Buffalo National Park, Victoria, Australia, where it occurs above 350 meters in woodlands and heathlands often amongst granite boulders.

<i>Acacia mearnsii</i> Species of flowering plant

Acacia mearnsii, commonly known as black wattle, late black wattle or green wattle, is a species of flowering plant in the family Fabaceae and is endemic to south-eastern Australia. It is usually an erect tree with smooth bark, bipinnate leaves and spherical heads of fragrant pale yellow or cream-coloured flowers followed by black to reddish brown pods. In some other parts of the world, it is regarded as an invasive species.
