The trunk is crooked and the bark vertically fissured. Roots are shallow and spreading. It has dense foliage with an open, spreading crown. Leaves 10–16 cm long and 1.5-2.5 cm wide with 3-8 parallel nerves, thick, leathery and curved. Flowers are 8 cm long and in pairs, creamy yellow and sweet scented. Pods are about 6.5 x 1.5 cm, flat, cartilaginous, glaucous, transversely veined with undulate margins. They are initially straight but on maturity become twisted with irregular spirals. Seeds are transversely held in the pod, broadly ovate to elliptical, about 4-6 x 3–4 mm. The generic name acacia comes from the Greek word ‘akis’ meaning a point or a barb and the specific epithet comes from the Latin ‘auricula’- external ear of animals and ‘forma- form, figure or shape, in allusion to the shape of the pod. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Acacia auriculiformis」の詳細全文を読む スポンサード リンク
