Several of Borneoâs plants challenge the senses-Rafflesia arnoldii, a parasitic species, produces the largest flower in the world, while the titan arum (Amorphophallustitanum) sporadically blooms into the largest unbranched inflorescence in the world.
Now, with territory up to the Mississippi River claimed and settled and the Louisiana Purchase explored, Americans headed west in droves. Newspaper editor John O'Sullivan coined the term manifest destiny in 1845 to describe the essence of this mindset.
O'Sullivan himself had earlier expressed some of these ideas, notably in an 1839 essay entitled The Great Nation of Futurity. O'Sullivan was not the originator of the concept of manifest destiny, but he was one of its foremost advocates. At first, O'Sullivan was not aware that he had created a new catch phrase. The term became popular after Whig opponents of the Polk administration criticized it.
