Phylogeography Of CAREX EBURNEA (CYPERACEAE) And The Systematics Of The CAREX EBURNEA Complex

The Carex eburnea complex (Carex Section Albae) is comprised of two named species, C. eburnea Boott and C. mckittrickkensis Ball. Carex eburnea is widely distributed on limestone in North America and C. mckittrickkensis exists at a single station in the Guadalupe Mountains of Texas. The purposes of the current study were 1) to generate a distribution map of the C. eburnea compolex, 2) to test the validity of the segregate C. mckittrickkensis, 3) to determine if past migratory routes can be inferred for the complex, and 4) to describe the genetic and morphometric structure of the C. eburnea complex within the context of competing species concepts.
