Read it through once

When the white man came the continent was nearly as poor, in variety of vegetation, as the desert of Sahara; now it has everything that grows on the earth. In fact, not Australia only, but all Australasia has levied tribute upon the flora of the rest of the world; and wherever one goes the results appear, in gardens private and public, in the woodsy walls of the highways, and in even the forests. If you see a curious or beautiful tree or bush or flower, and ask about it, the people, answering, usually name a foreign country as the place of its origin—India, Africa, Japan, China, England, America, Java, Sumatra, New Guinea, Polynesia, and so on.
