Abstract	Putative PISTILLATA genes were generated in nine species of Neillia, to examine the phylogenetic relationships among the species, and to test the hypothesis of hybrid origin within the genus. The PI genes determined in Neillia have two introns in the I-box region, which is consistent with PI genes in other Rosaceae. Phylogenetic analyses of the I-box region, including the introns, indicated that the species formerly classified in Stephanandra were nested within Neillia, supporting the taxonomic merger of the two genera. The PI data do not have a sufficiently strong signal to reject the hypothesis that Stephanandra is a hybrid in origin. The PI data, in conjunction with nuclear LEAFY, ribosomal DNA, and chloroplast DNA data, suggest that N. affinis might have been derived from hybridization between N. thibetica and N. gracilis. The phylogenetic position of N. affinis in the N. thibetica clade is supported by the PI and rDNA data, whereas N. affinis is also supported as a sister to N. gracilis in the LEAFY and cpDNA data. The pattern of phylogenetic placements of N. affinis in two different clades in two different sets of data suggests that the genome of the species might be comprised of a combination of the putative parental species.
