Based on nuclear and chloroplast sequences we resolve species relationships in Calycanthaceae and develop a biogeographic hypothesis that explains their intercontinental disjunctions and intra-continental diversification in eastern Asia. Fossil-calibrated penalized likelihood and Bayesian divergence time estimates indicate that the Northern Hemisphere Calycanthus and Chimonanthus diverged from ...

One of the most remarkable examples of intercontinental disjunction of the North Temperate Flora involves eastern Asia and eastern and western North America. Although there has been considerable interest in this phytogeographic pattern for over 150 years (e.g., Gray, 1859; Li, 1952; Graham, 1972; Boufford and Spongberg, 1983; Wu, 1983; Tiffney, 1985a, 1985b), relationships among taxa displaying...

PREMISE OF THE STUDY Thirty-one microsatellite markers were developed for Sinocalycanthus chinensis (Calycanthaceae), an endemic endangered species in China. METHODS AND RESULTS Twenty-one polymorphic and 10 monomorphic microsatellite markers of S. chinensis were developed using methods of biotin-streptavidin capture and capillary electrophoresis. The number of alleles per locus was one to 20...

Nine species of saprophytic hyphomycetes (anamorphic fungi), collected on plant debris from two different localities of southeast Florida, are recorded for the first time from the United States. They are: Anungitea fragilis, Beltraniella havanensis, Canalisporium caribense, Circinotrichum papakurae, Dictyosporium micronesicum, D. subramanianii, Dischloridium laeense, Gyrothrix verticillata and ...
