Acacia imbricata

There are a great many Australian species of Acacia with flowers like little yellow puff-balls, and these range from shrubs to trees. The one pictured is a shrub named Acacia imbricata, native to South Australia, and it generally attains a height of 3.3 to 7 feet (1 to 2 m). It flowers in winter, with a bright display of yellow. Some people classify Acacia in the family Mimosaceae, while others consider this a subfamily - Mimosoideae - within the Pea Family (Fabaceae).

Acacia imbricata

This shrub from South Australia has narrow deep-green phyllodes (this is the term for leaves which are actually flattened leaf-stalks). When it flowers, it makes a blaze of yellow puff-balls similar to many other Australian acacias. Acacias belong to the family Mimosaceae, sometimes classified as the subfamily Mimosoideae within the larger Pea Family (Fabaceae).

Acacia aphylla

Acacia is a very large genus in the Mimosoideae subfamilly of the Pea Family (some authors prefer to treat this group as a separate family - Mimosaceae), and Australia has more than its share of these. Acacia aphylla is certainly an oddity in the group, with its zig-zaggy spiky leafless branches, but when it comes into flower in late winter it makes its affinity to other species evident, since the little yellow puff-balls look much like those seen in numerous other species. It is native to an inland area to the east of Perth in Western Australia.

Acacia denticulosa

This unusual species of Acacia is notable for its large crinkly leaves with a sandpaper texture, as well as its fingers of bright yellow flowers. It belongs to the Mimosaceae Family (or alternatively to the Mimosoideae subfamily of the Pea Family - Fabaceae), and is native to Western Australia. It reaches a height of up to 12 feet (3.7 m).

Acacia podalyriifolia

Australia has an incredible number of attractive Acacia species, often with yellow flowers. This one is A. podalyriifolia, from the eastern side of the country in Queensland and New South Wales. It makes a bright display in late winter when its yellow puff-ball flowers emerge. The family may be considered as the Fabaceae, or Pea Family, or alternatively the Mimosaceae (for those who favor elevating the sub-families up to the family level).

Acacia chinchillensis

Australia is home to a large number of Acacia species (both shrubs and trees) with puff-ball flowers, often yellow in color. It must be noted that some of these have been a little too successful and have turned into invasive pests in some areas, but this beautiful species has not been a problem. It is a shrub to 6 or seven feet tall (2 m), with finely-dissected leaves. From near Chinchilla, Queensland on the eastern side of Australia. It belongs to the Mimosoideae subfamily of the Fabaceae, or Pea Family (some books treat this group as a separate family - Mimosaceae).
