Molecular Phylogeny and Biogeographical History of the Genus Agastache (Lamiaceae): Examining an East Asian-North American Disjunction.

Agastache, composed of 22 species, is a genus of aromatic flowering plants within the Lamiaceae (mints). The distribution of Agastache spans much of North America, but a single disjunct species, A. rugosa, occurs in eastern Asia. Lint and Epling (1945) conducted a thorough revision of Agastache and divided the genus into two sections, Brittonastrum and Chiastandra. Subsequently, Roger Sanders further clarified the taxonomy of the genus. To date, however, the taxonomy and sectional delimitations of Agastache have not been comprehensively investigated using modern molecular methods. Furthermore, the timing and route of the North America/eastern Asia disjunction have not been explored. Examining continental disjunctions and dispersal routes can lend insight into past speciation events and how organisms respond to environmental change. This historical evidence can inform models regarding future speciation events in the face of global climate change. Here, we present the first comprehensive DNA-base phylogeny of the genus Agastache. Additionally, we are using a Next Generation Sequencing approach to better understand species delimitations within the genus.
