|Family||Fabaceae, Subfamily Mimosoideae|
"Single-stemmed shrub or tree 6–12 m high." (WorldWideWattle ver. 2)
"...common in eucalypt woodlands and open forests, varying from single trees to a dominant component of the understorey." (WorldWideWattle ver. 2)
Although it may not be worth distinguishing between Acacia crassa subspecies on minesites we do nonetheless find subsp. longicoma commonly on reddish soils within its range and moisture availability may be higher. The seed collector may find the seed can be collected very efficiently in years when subsp. crassa may not have sufficient moisture to produce. The plant is common near Monto, Qld.
Distinguishing the subspecies may be done through studying of young plants. The phyllodes of subsp. longicoma are straight, measure to 20cm long, and are pubescent (downy, soft hair) whilst subsp. crassa is notable for its strongly falcate phyllodes to 30cm, which tend more to glabrous (no hair).
Acacia crassa subsp. longicoma has a distribution extending from the Sunshine Coast to Marlborough on the coastline and to Roma and Canarvon further inland.
