Unclogging the Pipes: Integrative Species Delimitation in Monotropsis (Ericaceae).
The genus Monotropsis belongs to the myco-heterotrophic subfamily Monotropoideae of the Ericaceae. As currently circumscribed,the genus contains only one species, Monotropsis odorata Schweinitz, a taxon endemicto the southeastern Unites States. It is found in the Appalachian Mountains from Maryland to Alabama, as well as occurring as a disjunct in central Florida. However, several species have been recognized in the past, most notably the Floridian endemic, Monotropsis reynoldsiae (A. Gray) Heller. Morphological, phenological, anatomical and preliminary molecular data have shown that more than one taxon exists within the genus. Molecular data using a broader sample of populations and loci shows continued support for conclusions drawn from the analysis of the other data sources. Taken together: geographic, morphological, ecological, and molecular data provide robust and compelling evidence for two species within Monotropsis by using a holistic approach to species delimitation. This is of particular interest as few of the genera within the subfamily are not monotypic. In addition, these genera often show highly discontinuous patterns of morphological, ecological, and molecular variation.
