Taxonomy and geographic distribution of Carex lucorum var. austrolucorum (section Acrocystis, Cyperaceae)
Poindexter DB and Naczi RF. 2014. Taxonomy and geographic distribution of Carex lucorum var. austrolucorum (section Acrocystis, Cyperaceae). Brittonia
Carex lucorum currently comprises two morphologically similar varieties. We revise the taxonomy of C. lucorum, and map the distribution of the taxa. Based on multivariate analyses and analyses of variance of measured characters, allopatry, and previous studies revealing differences in achene micromorphology, chromosome differences, and flavonoid chemistry, we elevate C. lucorum var. austrolucorum to species status as C. austrolucorum. We provide an identification key to C. lucorum and its closest relatives.
