Acacia longifolia is a species of Acacia native to southeastern Australia, from the extreme southeast of Queensland, eastern New South Wales, eastern and southern Victoria, and southeastern South Australia. Common names for it include Acacia Trinervis, Aroma Doble, Golden Wattle, Sallow Wattle and Sydney Golden Wattle. It is not listed as being a threatened species,[1][2] and is considered invasive in Portugal and South Africa.[3] It is a tree that grows very quickly reaching 7-10 m in five to six years.[4]

Standard Cyclopedia of Horticulture

Acacia longifolia, Willd. Sydney Golden Wattle. A tall shrub or small tree: phyll. oblong-lanceolate, either acute or obtuse, narrowed to the base, 2-3 in. or even 4-6 in. long and from 1/4-1/2in. wide; 3 or 4 longitudinal nerves, reticulately veined between; gland very near base: fls. in spikes 3/4-2 1/4 in. long, 4-merous: pods l 1/2-3 3/4 in. long or more, about 1/4in. broad, coriaceous, terete until fully ripe when their valves flatten, separate, become dark and curled and persist on the tree; seeds longitudinal, black, fat and shining; funicle silvery, not enfolding seed but bent upon itself several times, dilated and fitted like a cap over one end of the seed; ripe Aug, Sept. Fls. Feb., March.—A valuable ornamental as well as a good tree for narrow streets; also used as a tan for heavy leathers.

Var. Sophorae, F. v. M. (A. Sophorae, R. Br.). Phyll. shorter, and with rounded apex, 1 1/2-3 1/2in. long, 3/4-1/12in. broad: spikes generally shorter, l-l 1/2in.; blooms later and seed matures later than type. Brown, Fl. of S. Austral.—Under cult, it becomes difficult to distinguish this from the type, but in general its foliage is shorter and more rounded at apex.

Var. floribunda, F. v. M. A tall shrub or small tree, with the foliage all at the ends of the branches, giving the tree a thin, delicate appearance: phyll. 2 1/2-31/4 in. long, 1/8-1/4in. wide, or more, linear-lanceolate, ending in oblique point, acuminate, striate, several nerves more prominent than others: spikes 1 l/2 in. long, flowering to base; fls. whitish yellow: pods contracted and long-constricted between seeds; seed longitudinal; funicle silvery, not encircling seed but folded like a cap; ripe July, Aug. Fls. Feb., March. B.M. 3203 (as A. intermedia).—This varies so much from the type that it is difficult to conceive of its relationship, but since all variations between this and the type can be traced, it can be given only varietal rank.
