Acacia caerulescens, commonly known as limestone blue wattle, Buchan blue or Buchan blue wattle is a tree species that is endemic to south eastern Australia.
Description
The tree grows to between {{cvt|10|and|15|m}} in height and has a pyramidal habit with glabrous branchlets that have a fine white powdery coating. Like most species of Acacia it has phyllodes rather than true leaves. The evergreen phyllodes have an obovate to oblanceolate or sometimes narrowly elliptic shape with a length of {{cvt|4|to|8|cm}} and a width of {{cvt|1.5|to|3|mm}}. The lemon yellow globular flowerheads appear in racemes from November to December in the species' native range, followed by seed pods that are 5 to 12 cm long and 1.4 to 2.2 cm wide.{{Flora of Australia Online|name=Acacia caerulescens |id=40909}}
Taxonomy
