Using Morphometrics To Evaluate Taxonomic Relationships In Eleocharis Tenuis (Cyperaceae), Lane D. Gibbons
Masters Theses, 2010-2019
North America is host to multiple complex taxa, and unresolved relationships in the genus Eleocharis (Cyperaceae). Of noteworthy significance, are lasting taxonomic uncertainties involving plants referable to E. tenuis (var. tenuis, var. verrucosa, and var. pseudoptera) of the E. tenuis species complex. Morphology of E. tenuis is traditionally recognized as being widely variable, and intermediate among taxa along a broad geographic gradient. Cytological and morphometric data however, indicate that the varieties of E. tenuis are unique in cytology, and are consistently delimited by five morphological characters. Furthermore, this study shows that cytological data correlates with unique morphological …
