|Angle leaved wattle|
Acacia truncata, commonly known as the angle leaved wattle or west coast wattle, is a coastal shrub in the family Fabaceae, with a native distribution along the southwest coast of Western Australia. A specimen of this wattle was part of an early European botanical collection, perhaps the first from Australia.
The shrub is a dense and dome shaped plant 0.5 to 2.3 metres (2 to 8 ft) high. It has ribbed and glabrous branchlets. Flowerheads are globe-shaped and composed of 7-16 pale yellow flowers, on stalks between 10 and 25 mm (0.39 and 0.98 in) long. Following flowering it will form blackish curved to linear seed pods that are about 6.5 centimetres (2.6 in) in length and 2 to 4 millimetres (0.079 to 0.157 in) wide with thick yellowish margins. The shiny brown seeds are longitudinally arranged in the pod. They have an oblong to elliptic shape and are 3 to 3.5 mm (0.118 to 0.138 in) long. Like many other Acacia species, A. truncata has phyllodes rather than true leaves. The triangular phyllodes range from 9 to 25 mm (0.35 to 0.98 in) long and 5 to 13 mm (0.197 to 0.512 in) wide.
It was first formally described as Acacia truncata by the botanist Johann Centurius Hoffmannsegg in 1824 as part of the work Verzeichniss der Pflanzenkulturen in der Gräflich Hoffmannseggischen Garten zu Dresden und Rammenau.
A. truncata is found along the west coast of Western Australia extending from the Mid West through the Wheatbelt and Peel and into the South West. It is found as far north as Carnamah and as far south as Harvey. It grows in sandy and skeletal soils and is found among sand dunes and patches of coastal limestone as part of coastal heath communities.
Cultivation and Uses
The plant commercially available as seedlings in seed form. It is easily propagated from seed collected in December or January. The seeds need to be treated with hot water treatment or lightly scarified prior to planting. It grows best in a free-draining seed-raising soil mix. The species is used for restoration work, particularly in coastal areas, in mixed plantings with other low shrubby species such as Olearia axillaris, Lomandra maritima and Scaevola crassifolia. A. truncata requires some protection from strong winds. It is tolerant of frost and salt water spray making it ideal for coastal gardens.
