Phylogeny and historical biogeography of the small, intercontinentally disjunct genera Epigaea and Rhodothamnus.
Within the tribe Phyllodoceae (Ericaceae: Ericoideae), a strongly-supported clade comprised of Epigaea and Rhodothamnus occurs. Epigaea includes three species: Epigaea repens occurs in Eastern North America, E. gaultherioides occurs in the Caucusus, and E. asiatica occurs primarily in Japan. Rhodothamnus includes two species, R. sessilifolius and R.chamaecistus, which are found in the Alps and Caucasus. A phylogeny was generated within the context of the broader Phyllodoceae using Bayesian,Maximum Likelihood and Maximum Parsimony analyses. An examination of the historical biogeography of the group was conducted using multiple approaches,including a newly available program, RASP (Reconstruct Ancestral State inPhylogenies) using the Bayesian phylogeny.
