Acacia aphylla, commonly known as the leafless rock wattle(오스트레일리아에서 부르는 아카시아속),[1] twisted desert wattle or live wire,[2] is a species of Acacia which is endemic to an area around Perth in Western Australia.
Description
A. aphylla is spiny and leafless erect and widely branching shrub that grows to 0.9 to 3 metres (3 to 10 ft) in height[3] and with a width of approximately 2 metres (7 ft).[4] The generally bright green branchlets are rigid, terete and obscurely ribbed. They are smooth, glaucous, glabrous and coarsely pungent (뾰족한). Unlike most Acacia the phyllodes are absent for A. aphylla'.[5]
The thickened blue-green wiry stems have the ability to photosynthesize like leaves so giving the plant an evolutionary adaptation that greatly reduces the total surface area for water loss through transpiration.[2]
A. aphylla produces yellow spherical flowers between August and October (late winter to mid spring) in its native range.[3] The inflorescences have a simple structure with one per axil. The peduncles are 7 to 10 millimetres (0.28 to 0.39 in) long and glabrous with globular heads. They hold 20–30 flowers that are a bright light golden colour. The flowers are 5-merous with free sepals. Seed-pods form later that are linear, 3 to 9 cm (1.2 to 3.5 in) long and 3 to 4 mm (0.12 to 0.16 in) wide containing black seeds that are longitudinal and oblong and about 4 mm (0.2 in) long.[5] Pods are mature from December to March.[citation needed]
Plants are mostly killed by fire but populations will regenerate from the soil seedbank.[1]
