Common names for trees are the scourge of plant taxonomists, botanists, foresters and ecologists. Being one trained in a biological/natural science, not knowing the scientific name of all local trees is akin to having only half an education. However, many folks are not schooled in the binomial system for plant taxonomy. This systematic method of naming plants dates back to the Ancient Greek philosopher Theophrastus, approximately 2,000 years ago and subsequently improved upon by the Swedish naturalist Carolus Linnaeus (1707-1778). Linnaeus sought to bring order to the naming of plants by giving them one botanical name and thus avoid the problem of having many common names for the same species, or, even worse, a common name that may refer to more than one species.

At the UT Arboretum I am constantly challenged to identify plants by verbal description and/or reference by a local common name. For example, I was asked, “what’s the name of the tree that looks like it’s dead in the winter . . . My dad called it the dead tree.” Well, I say, your dad was correct!

This questioner could have equally supplied other common names, of which I may not have been so certain, such as chiot, chico du Canada, chiot tree, American mahogany, mahogany, geweihbaum, nettle-tree, nicker-tree, and stump tree. (I’m probably driving the botanists nuts by now!) However, if he had referred to it as the coffeebean-tree, coffeenut, coffeetree, or Kentucky coffeetree, then perhaps you, too, could have conversed with the questioner on his footing.

Interestingly, behind most common plant names, there is usually a story, and a lesson in natural history. These names may have their roots in the historical uses of a plant; describe the characteristics of the leaves, flower, or wood; or describe the habitat or geographical location where it might be found. Ponder the common names of some trees with which we are most familiar – dogwood, silverbell, sugar maple, mountain maple, honey locust, yellow-poplar, slippery elm, and pignut hickory. If you really want to become an aficionado of the common names of plants, you might want to trace them to their Gaelic origin (reference: http:www.unc.edu/home/reddeer/gaelige/plants.html)

Oh, how I relish the challenge of the common names!
