Description

A. latzii is a shrub or tree which grows to a height of 3 to 7 m (9.8 to 23.0 ft). The branchlets may be smooth or have a sparse covering of minute flat lying hairs. The phyllodes (5 to 10 cm (2.0 to 3.9 in) long by 2 to 4 mm (0.079 to 0.157 in) wide) are narrowly linear and generally with a shallow incurving. They are leathery and a khaki to greyish green and like the branchlets may be smooth or have a sparse covering of fine hairs. They have many closely parallel veins. The inflorescences are two to five headed racemes with the raceme axes being 1.5 to 5 mm (0.059 to 0.197 in) long. The flower stalks are 5–9 mm long and have a covering of fine hairs. The heads are globular (4 mm (0.16 in) in diameter) with 13 to 18 flowers. The flowers are 5-merous and the sepals are free. The smooth, leathery pods are up to 15 cm (5.9 in) long. The dull, brown-black, oblong seeds are 5.5 mm (0.22 in) in length. [4] It flowers from April to August and fruits from February to November. [1]

Habitat

It is found growing in skeletal alkaline soil in gullies and on minor hill slopes. [4] [6]

Conservation status

It has been declared "vulnerable" under both Commonwealth and Northern Territory legislation. [1] [7] It is threatened by

Taxonomy

It was first described by Bruce Maslin in 1980 [2] and named A. latzii to honour Peter Latz whose "fine" collections were the basis of Maslin's descriptions. [3] An isotype, CANB 267113.1, was collected by Latz in the Beddome Range, New Crown Station, on 21 April 1977 [8]
