Abstract

Pieris is an eastern Asian (EA)-eastern North American (NA) disjunct genus with P. cubensis in the West Indies (WI). In this study, we inferred interspecific relationships within the genus using nucleotide sequences of nuclear (nrDNA ITS and ETS) and chloroplast (matK, trnL-F, and psbA-trnH) markers. Pieris nana is sister to the clade comprising the rest species of Pieris, i.e., Pieris subg. Pieris. The species of subg. Pieris diverge consecutively in the order of Pieris cubensis, P. swinhoei, P. floribunda, P. phillyreifolia, and P. formosa plus P. japonica. Neither section Phillyreoides nor section Pieris is monophyletic, and P. phillyreifolia of NA is more closely related to EA species (P. formosa and P. japonica) than to the other NA species (P. floribunda). Morphological characters (such as inflorescence position, testa cell shape, and placenta attachment) used to define the sections are homoplasious, having evolved more than once in Pieris. Dispersal and vicariance analyses suggest that ancestral populations of Pieris were widespread in EA+NA+WI, and two dispersal events may have occurred from the New World to the Old World. Pieris cubensis may have originated as the result of a dispersal event from NA+EA during the early diversification of Pieris in the late Eocene.
