Like many species in the mint family, Monarda fistulosa L. (Lamiaceae), commonly known as wild bergamot, bee balm or horse mint, produces small volatile chemicals called monoterpenes in tiny sacs (trichomes) located on leaves, calyces and even flower petals. When one rubs bee balm leaves, these trichomes are broken and almost immediately one detects the scent of escaping monoter- penes. Also known as essential oils, monoterpenes have been used by humans for thousands of years as fragrances and flavors; however, plants use them for a variety of functions, including: suppres- sion of plant competitors, repelling herbi- vores or attracting pollinators and seed dis- persers (Harbome 1993). Monoterpenes are widely distributed among a variety of plant families and their variation in natural plant populations has been extensively studied. Many labiate species contain individuals with distinct chemical pheno- types, called chemotypes, which are con- trolled by simple Mendelian genetics (Vernet et al. 1986, Vokou et al. 1993). Plants of a particular chemotype usually produce one monoterpene that dominates their total essential oil composition. This means that individuals of the same species can have very different smells, tastes and interactions with other organisms, such as herbivores and pollinators. Prior to my work, three chemotypes had been identi- fied in Monarda fistulosa, containing either geraniol, carvacrol or thymol as their main monoterpene (Marshall and Scora 1972, Weaver et al. 1995, Johnson et al. 1998). The smell of geraniol is sweet or lemony - it is a major component of lemon oil, whereas carvacrol and thymol remind one of thyme or oregano, both of which have these chemotypes. While the exis- tence of these three chemotypes in M. fis- tulosa has been known since the early 1970s, only one study presented detailed information on the distribution of chemo- 1972). I have discovered that two of the known M. fistulosa chemotypes, carvacrol and thymol, occur in Colorado in pure and mixed populations. Additionally, in one population in southern Colorado, I have found a previously unknown chemotype for this species with essential oil composed almost entirely of the monoterpene linalol. With the support of a Colorado Native Plant Society research grant from the John Marr Fund, I have been characterizing the chemotype variation of M. fistulosa over the landscape and trying to understand how these patterns arose and how they are maintained. The first step to understanding chemical polymorphism in M. fistulosa was to map chemotype patterns of populations. The methodology I used was simple. Using historic herbarium records, information from locals and by just driving around, I located about 50 populations of wild berg- amot throughout the state. At each site I randomly collected a single leaf from an average of 20 plants, soaked them in pure ethanol for one week to extract the monoterpenes and then analyzed the solu- tion by gas chromatography, a technique that allows separation, identification and quantification of monoterpenes. Chemical analyses of over 900 Colorado plants revealed variation ranging from populations comprising only carvacrol plants to populations comprising only thy- mol plants, as well as populations com- prising various mixtures of the two. So, what factors are responsible for these pat- terns? One explanation may be tempera- ture. In Boulder County, where almost half of the populations analyzed occur (Figure 1), it appears that populations high in thymol plants are found at higher eleva- tions or in colder areas, such as deep canyons. These micro site differences may be important in M. fistulosa, since in Colorado it has a large geographical range over most of the state with diverse habitats from prairies to high mountain meadows. Also, the idea that plants of a particular to temperature has been shown for com- mon thyme {Thymus vulgaris) in the south of France. In the case of thyme, certain chemotypes were absent from the floor of an enclosed basin that regularly experi- enced much colder temperatures than the surrounding uplands (Amiot et al. 2005). To unravel this question in M. fistulosa, I plan to monitor temperature, humidity and other abiotic parameters at sites with dif- ferent chemotype compositions. Another factor that may shape the chemo- type composition of populations is her- bivory. At a few sites, I have found plants being fed upon by a small tortoise beetle {Physonota unipunctata Coleoptera: Chrysomelidae) that specializes only on M. fistulosa. The larvae of this beetle have a curious defense mechanism; they accu- mulate their feces on two projections on the rear end of their bodies, which they curl upward, holding the "fecal shield" over their bodies. Since their diet consists exclusively of M. fistulosa, the fecal shield is rich in plant monoterpenes, adding a chemical dimension to their defense strate- gy. While the beetle larvae will readily feed on both chemotypes, my preliminary data show that when fed only carvacrol foliage they have lower survival and longer development times. Thus, in popu- lations where these herbivores feed, thy- mol plants may experience more damage and reproduce less than carvacrol plants. Another interesting find along my chemi- cal odyssey was the discovery of what appears to be a new chemotype of M. fistu- losa. On a lonely stretch of highway west of Trinidad, Colorado, I spotted an isolated roadside population. Initially, the plant leaves I collected all seemed to have the familiar smell of carvacrol or thymol chemotypes found at many other sites. Suddenly, the scent of one plant was com- pletely different from any other I had pre- viously encountered. Upon returning to my laboratory, I immediately started my gas chromatograph and eagerly watched the monitor as the sample ran. The results Vol. 30 No. 2 Page 4 Aquilegia showed one main peak, which was the monoterpene linalol. While linalol has been identified in a closely related species, M. didyma, no one has ever reported this compound in M. fistulosa. As grandiose as it may sound, I felt I was witnessing an evolu- tionary event, where a new mutant phenotype had appeared, and if it had some heritable advantage over the resident chemotypes, the linalol chemotype may increase. Then again the plant may get mowed by the road maintenance crew before setting seed, a fate for which its new mutation would be useless. Anyway, the next time you are hiking and encounter wild bergamot in the wild, don't forget to stop and give it a sniff. You may not find a new chemotype, but you will sample just a little of the olfactory genet- ic diversity that makes up M. fistulosa in Colorado. References Amiot, J., Y. Salmon, C. Collin, and J. D.
