What makes a plant rare?

Questions from our readers:
Sully, from Arcadia, asks, "What makes a plant rare?"
I am glad you asked that question, Sully. This reminds me of the words of Pierre Loupgarou, the acclaimed botanist from Mendication University in Skandia. In his classic work, The Growth and Management of Dreams, he wrote: "Rarity is not a condition but a perception that progresses until one is unable to identify anything at all." I would have to agree, although lately, I am not so sure. Have you noticed how the plants in the guidebooks don't always look like the one you have in your hand? Have you noticed that the phenomenon increases as the years go by? There is a simple, elegant explanation. It is your evolutionary process hard at work in the academic community! Yes, although once shielded from the forces of natural selection and genetic drift by a system of entitlements, professional societies, tenure, grants, and mutualism, academia is now rife with adaptations. Like a flood of Norway rats spilling over the gunwale of the Mayflower and swimming toward shore, evolution has invaded the community, resulting in a massive speciation and extinction. Eusocialty, theory diversity, and critical resistance is on the rise. Trophic cascade has impacted pensions, internships, research, funding, staffing, office furniture, even publications. So, it is no surprise to find studies showing that, while plants in the field will stay morphologically and functionally equivalent over time, plants in the professional journals will exhibit gradual changes in morphology over the same period, particularly in reproductive structures. Current theory holds that the rapidly changing conditions now found on campus are a prime factor. Many new species are appearing in the journals; some report as many as one an hour. As a result, it is inevitable that a species will become completely unrecognizable. So take heart, you are not seeing things, in fact, you are not seeing anything at all.
