The majority of the species flower during the end of winter or the beginning of spring. The largest Arcacias is the Blackwood Wattle (Arcacias melanoxylon), which is found within the eastern and southern parts of Australia. The most common Arcacias is the Golden Wattle (Arcacias pycnantha), which is found in the South Eastern parts of Australia, as well as the hotter and drier climates.

Banksias (Banksia spp)
There are 76 different species of Banksia, with a total of 75 found naturally in Australia. The greatest range of Banksias are found in South Western Australia, with a number of others found within the Eastern parts of Australia. However, Banksias are generally not found within the rainforests along Australia's Eastern Coast or within the more arid regions of Australia. Banksias can survive in poor quality soils unsuitable for most other plants. The Banksias branches spread upwards, and hold spikes topped with orange, red and yellow flowers. Sir Joseph Banks (1743-1820) was the first European to collect specimens of Banksias in 1770, which is where these plants got their name. The sweet nectar from Banksias, was also used by the Aboriginal people to make a drink.

Boabs are relatively small in comparison to other trees found around Australia, with their height reaching upto about 20 metres.
Bunya Pine (Araucaria bidwillii)
The Bunya Pine is endemic to Queensland, Australia. The natural habitat of the Bunya Pine is within the ranges and rainforests around Brisbane and Southern Queensland. However, the Bunya Pine can grow in many places around Australia and the world.
The Bunya Pine is a large tree with a straight trunk, which can grow to around 45 metres high. It carries prickly leaves, male pine cones, and female pine cones which contain edible seeds and can weigh upto 10kg. Although the Bunya Pine only harvests cones every three years, the cones are plentiful and were traditionally used by Aborigines as a food source.
Cabbage Palms (Livistona mariae)
Cabbage Palms are unique to Central Australia, in particular the area surrounding Alice Springs. They have tall thin trunks, which can reach heights of about 30 metres, with short branches of rich green leaves sprouting from the top.

Eucalyptus (Eucalyptus spp)
Eucalypts are one of Australia's most well known trees, and often referred to as Gum Trees. There are about 700 species of Eucalypts, which can be found all over Australia. The different species vary greatly in size and shape and require various environments to survive.

Grevilleas is a shrub, and 230 of the 250 different species are native to Australia. Grevilleas range in colour, although all have thin spreading petals. One of the smaller species of Grevilleas includes the Banks Grevillea (Grevillea banksii), while one of the large includes the Silky Oak Grevillea (Grevilliea robusta), which grows to about 30 metres tall.
Kangaroo Paw (Anigozanthos spp)
Kangaroo Paw is often seen in gardens in eastern Australia, although grows in the wild in Western Australia.

Melaleucas are commonly referred to as Paperbarks due to their paper like bark which peels from the trunk. The dead peeling bark enables moisture to stay within the trunk, at the same time as protecting the tree from extreme weather conditions. There are several different varieties of Melalucas with the most commonly seen being the Bracelet Honey-Myrtle (Melaleucas armillaris), Long-Leaved Paperbark (Melalucas leucadendron), and the Swamp Paperbark (Melalucas ericifolia). Melalucas have also traditionally been used by Aborigines in a water source (from within the trunk) and as a building material for various objects (the bark itself).
