Dwarf Rock Wattle  |  

Acacia pygmaea

Status: Endangered on the EPBC Act list

Acacia pygmaea, Family Mimosaceae, also known as Dwarf Rock Wattle, is an erect single stemmed shrub, 30–70 cm high with globular flower heads that are cream/white, ageing to orange. The green, leaf-like phyllodes are crowded, erect, 20–30 mm long and 9–13 mm wide, and are 1-nerved or imperfectly 2-nerved. The species flowers from November to March and the flowers are probably pollinated by insects. The species produces relatively few fruits and each pod contains 2–3 seeds. Most acacias fruit and shed their seed a short time after flowering, but the pods of this species take a year to mature. Flower buds and unopened pods may be found on the plant simultaneously. Seed has been collected in late October.
