Plant Biology Violaceae Viola virginiana new species phenetic microsatellites The genus <i>Viola</i> (Violaceae) encompasses 1,000-1,100 species and includes one of the largest North American groups, the "acaulescent blue" violets (subsection <i>Boreali-Americanae</i>). In the subsection, the <i>Viola pedatifida</i> species group is distinctive in producing only divided leaf blades. Presently the group consists of <i>Viola pedatifida</i> G. Don., <i>Viola brittoniana</i> Pollard, and <i>Viola subsinuata</i> (Greene) Greene. Recent fieldwork in the mountains of Virginia suggested that disjunct populations of <i>V. pedatifida</i> were different than Midwestern populations. Macromorphological, micromorphological, genetic, and ecological data were analyzed to compare taxa. Phenetic analyses of leaf, flower, cleistogamous capsule and seed variables and scanning electron microscopic examinations of seed coats and petal trichomes distinguished four species. Genetic studies using four microsatellite loci and microhabitat data indicated genetic and ecological differentiation among the four species. All evidence support recognition of the Virginia violet as a narrowly endemic species, <i>Viola virginiana</i> Zumwalde & H. E.
