A Tale of Two Pygmy Pipes: Quantifying Variation in Monotropsis (Ericaceae).
Monotropsis is a genus of uncommon mycoheterotrophic plants endemic to the southeastern United States. Most recent taxonomic treatments treat the genus as monotypic, but past authors have recognized up to three species, based on variation in floral characters and differences in flowering time. No explicit quantitative analyses have previously been performed to assess this variation. We examined morphological and molecular variation across the range of the genus and conclude that while entities that were defined based on differences in phenology are not distinct, there is a significant pattern of variation to warrant recognition of two species, M. odorata Schwein., found in the Appalachian Mountains from Maryland to northern Georgia, and M. reynoldsiae (A. Gray) Heller, restricted to north-central Florida. Recognition of the latter, which is a very uncommon species, has conservation implications.
