Acacia leptocarpa, commonly known as north coast wattle,[1] is a shrub or small tree native to New Guinea and coastal regions of northern Australia.

the glabrous phyllodes have a visible gland on the upper margin with longitudinal and parallel veins, three of which are more prominent than the others.

[2] It blooms from Autumn to Spring[1] and produces pleasantly perfumed yellow coloured inflorescences on spikes that are around 5 to 7 cm (2.0 to 2.8 in) and found in groups of two in the leaf axils.

The shiny dark brown to black seeds within the pods are arranged longitudinally and have a length of around 4 mm (0.16 in)[2] with a large yellow-orange aril.

The natural range extends from Carlton Hill Station in the Kimberley region of Western Australia eastwards across the Top End of the Northern Territory to Cape York Peninsula and southwards to Southern Central Queensland where it is found along the margins of watercourses and swampy areas[2] growing in sandy or rocky soils occasionally around laterite as a part of open Eucalyptus or Melaleuca woodland communities.
