The Acaulescent Blue violets (subsection Boreali-Americanae (W. Becker) Gil-ad) are a taxonomically challenging group in Viola due to their frequent hybridization and polymorphic variation, causing debate and resulting in divergent species delimitations among taxonomic specialists over the past century. One of these species, Viola subsinuata (Greene) Greene, is a homophyllous violet that expresses a wide range of morphological variation causing confusion among specialists. Recent fieldwork in the mountains of western Virginia, as well as common garden observations and laboratory studies, have suggested that V. subsinuata is a complex containing several distinct evolutionary species. This investigation used an integrative taxonomic approach to generate morphological, environmental, genetic, and reproductive data on the study taxa in Virginia, and applied the Unified Species Concept to detect and delineate distinct evolutionary species in the V. subsinuata complex. In most cases, the data sets supported recognition of five distinct evolutionary species: V. subsinuata sensu stricto, V. “Blue Ridge”, V. “tenuisecta” (a closely related species studied by Bethany Zumwalde), and two other species included for comparison or potential parents of hybrid plants, V. palmata L. and V. sororia Willd. The study highlighted the narrow regional endemic nature of V. “Blue Ridge” in Virginia's (and North Carolina's) Blue Ridge province. 2018-10-01 English text Ohio University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ohiou153185551690636 http://rave.ohiolink.edu/etdc/view?acc_num=ohiou153185551690636 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
