Flora of Australia - Vascular Plants

Vascular Plants

Australia has over 30,000 described species of vascular plants, these include the angiosperms, seed-bearing non-angiosperms (like the conifers and cycads), and the spore-bearing ferns and fern allies. Of these about 11% are naturalised species; the remainder are native or endemic. The vascular plant flora has been extensively catalogued, the work being published in the ongoing Flora of Australia series. A list of vascular plant families represented in Australia using the Cronquist system is also available.

At the higher taxonomic levels the Australian flora is similar to that of the rest of the world; most vascular plant families are represented within the native flora, with the exception of the cacti, birch and a few others, while 9 families occur only in Australia. Australia's vascular flora is estimated to be 85% endemic; this high level of vascular plant endemism is largely attributable to the radiation of some families like the Proteaceae, Myrtaceae, and Fabaceae.

Famous quotes containing the word plants:

    What I did not yet know so intensely was the hatred of the white American for the black, a hatred so deep that I wonder if every white man in this country, when he plants a tree, doesn’t see Negroes hanging from its branches.
    Jean Genet (1910–1986)
