Acacia asparagoides

Acacia asparagoides is a shrub to 2 metres tall.

It has a restricted distribution, occurring only in NSW, confined to the Blue Mountains, between Newnes Junction and Lawson. Here, it grows in dry sclerophyll forest and heath on sandstone. One specimen has been collected from the North Coast on the Boonoo Boonoo River (which likely requires more investigation).

Australian Wattles at least, can be broadly placed into 1 of 3 recognisable groups:

• Group 1: Those that produce juvenile compound-bipinnate leaves and then change to producing adult-phyllodes which are modified-flattened petioles which form the foliage. This is combined with flowers produced in globular balls or heads (or ovoid heads). The heads can be singular in leaf/phyllode axils or arranged in groups.
• Group 2: As for Group 1 but flowers are produced in longer rod-like spikes.
• Group 3: Those that never produce phyllodes and retain the juvenile compound-bipinnate foliage into adulthood. These always produce flowers in globular balls (which are secondarily arranged into panicle or raceme-like groups in many cases).

This wattle belongs to Group 1.

Phyllodes (modified leaves) sometimes clustered, linear, to 1.5 cm long and to 0.2 cm wide.

Flowers are produced in globular heads, to 6 mm in diameter, bright yellow, mainly with one head produced per leaf axil. Each head can contain up to 30 very small, staminate flowers. It flowers mainly in August–October, but also other times of the year.

Seed pods are shallowly to strongly curved, usually slightly constricted between seeds, to 5 cm long, and about 0.5 cm wide.
