Abstract

Phylogenetic analyses of the five extant species of Chamaecyparis (Cupressaceae) based on mDNA ITS sequences yield a single most parsimonious tree in which C. pisifera (Japan) and C. formosensis (Taiwan) form a clade that is sister to a clade including C. lawsoniana (western North America) and C. obtusa (Japan and Taiwan) plus C. thyoides (eastern North America). Dispersal-vicariance analyses (DIVA) suggest a minimum of two dispersal events between eastern Asia and North America.
