Acacia victoriae és una espècie de planta de la família de les lleguminoses nativa d'Austràlia.^[3] És un arbre perenne que es troba sobre gran varietat de sòls al llarg de rius i rierols, i a planures salines. És una espècie que té usos culinaris, forratgers i anticancerosos.

Descripció

Acacia victoriae és un arbust o arbre petit que normalment fa uns 5 metres d'alçada però pot arribar fins als 9m. La capçada és desordenada i difusa. Presenta un tronc curt únic o escassament ramificat més aviat tort amb les branques les quals sovint inverteixen en estípules espinoses (especialment evident quan són joves, habitualment absent en plantes madures), arrelen fàcilment i a vegades formen matolls. L'escorça és prima, llisa o finament fissurada. ^[4]

Taxonomia

Acacia victoriae va ser descrita per Bentham, George i publicada a Journal of an Expedition into the Interior of Tropical Australia 333. 1848. (J. Exped. Trop. Australia)^[5]

Etimologia

• Acacia: nombre genérico derivado del griego ακακία (akakia), que fue otorgado por el botánico Griego Pedanius Dioscorides (A.C. 90-40) para el árbol medicinal A. nilotica en su libro De Materia Medica.^[6] El nombre deriva de la palabra griega, ακις (akis, espinas).^[7]
• victoriae: epítet específic que fa referència al riu Victòria (ara riu Barcoo). Thomas Mitchell va collir el tipus en 1846 a prop de l'actual població de Tambo al riu Barcoo.

Acacia victoriae, commonly known as gundabluie or bardi bush, is a shrub-like tree native to Australia.^[1] Subspecies: A. victoriae subsp. arida Pedley^[1]

Distribution and ecology

Found in arid and semi-arid areas,^[2] the Acacia victoriae is generally found in alkaline soils including clayey alluvials, grey cracking clays and saline loams on floodplains, alluvial flats, rocky hillsides and ridges.^[3] Animals such as birds and small mammals are known to use the tree as protection. The seeds and foliage also offer a source of food to animals.^[4]

Description

Mature Acacia victoriae grow into a shrub-like tree with multiple trunks. They reach a height of about 5–6 meters and are moderately fast growing. It has a life-span of about 10–15 years. The tree has a large root system, known to extend to 20 metres (66 ft). It is able to survive drought fairly well, however not in severe drought, though it can regenerate from suckers. Flowering begins in August and continues into late December; depending on the region the tree is found. As with the variation of flowering, the maturation of the seeds is also variant.

Foliage and seeds

The branches of Acacia victoriae are covered in small spines that are about 1 cm in length. During flowering, the branches are full clustered, yellowish, and strong scented flowers. Each flower is in a pair within the 12–12 cm cluster. Seeds are found in 8 cm pale coloured pods. The seeds themselves are about 0.5 cm and brown in colour.

Uses

Food

The nitrogen-containing seeds are used in breads as well as ground up as a meal. Aboriginals are helping to apply their methods to using the seeds from Acacia victoriae for food. The seeds have also been used as fodder, being a good source of protein.

Land uses

The Acacia victoriae is useful when used as a windbreak and also helps with soil stabilization. Because it is able to grow at a moderate rate, it has also been used as site rehabilitation.
