Build Botany for National Security

Let's see, the dwindling of botany as a field of study among the biological sciences seems to suggest that no one worries about being miserable, naked, or hungry. So let's try this.
Wake up America! As botanical knowledge declines, our national security is threatened as so aptly demonstrated by this cartoon. All those alien trees creeping into our landscape could be harboring terrorists, socialists, or even tree-hugging liberals! But would you ever know, native versus indigenous? The Phactor has long wondered if the Princess Tree invasion might be at the root of China's successful espionage efforts in the USA. Didn't you notice how many and how quickly they have sprung up around the Pentagon? The camera lens protruding from the tree holes, it's a dead give away, but first you have to cure the tree blindness of our security community! Just a billion or two would give my taxonomy and plant identification class a real shot in the arm, and none of it would be wasted either, but a Phytophactor logo will be needed for the doors of the Hummer field vehicles.
