Cotyledons orbicular to obovate, about 2.2 x 1 mm, petioles about 1.2 mm long. First pair of leaves about 4.5-5 x 2 mm. Oil dots small, closely spaced. At the tenth leaf stage: leaf blade about 40 x 3 mm, lateral veins about 5 or 6 on each side of the midrib. Petiole about 2.5 mm long.
Distribution and Ecology
Endemic to Australia, occurs in WA, NT, CYP, NEQ and southwards as far as coastal and inland central Queensland. Altitudinal range in northern Australia from near sea level to 400 m. Grows as a rheophyte in riparian and gallery forest on sandy creek banks.
Although this tree can grow large, it will flower as a shrub. It is a very useful ornamental for moist areas in larger gardens. Its foliage is silvery, the cream, perfumed 'bottle brush' flowers attract numerous bird species.
This species may have been used as fish poison. (http://share.geocities.com/Athens/Delphi/2970/poi son.htm)
