Rugelia nudicaulis

Rugelia nudicaulis (Rugel's Indian plantain [1] or Rugels ragwort), the sole species of the genus Rugelia, blooms in summer. It is a wildflower endemic to higher elevations in the Great Smoky Mountains. [2] It is a rare species in Tennessee. [3] First placed in the genus Senecio , then moved to Cacalia it was finally placed in a genus of its own, Rugelia. Genetic diversity in this plant, assessed using allozymes, is so low that the species may not survive changing environmental conditions. [4]

Many species of wildflowers are native to New England. There are four important community types which show considerable diversity and blending across this United States physiographic region. These are: alpine, coniferous forests, northern hardwood forests, and wetlands. Wetlands may be further subdivided into bogs, swamps, and bottomlands. This article lists some of these Wildflowers of New England and references sites for further research.
