The Origin of New Natural hybrid, Goodyera × maximo-velutina (Orchidaceae) from Jeju Island, Korea

JI-HYEON SO, NAM-SOOK LEE

Abstract


We describe a new taxon of Goodyera (Orchidaceae), G. × maximo-velutina from Jeju Island. This taxon is presumed to be a natural hybrid between G. maximowicziana and G. velutina based on morphological characteristics, i.e., leaf margin, leaf venation, hairiness and color of floral bract, pedicel and ovary. We analyzed ITS of nuclear DNA and three noncoding regions of chloroplast DNA (trnH-psbA, trnS-trnG, trnL) for elucidating the hybrid origin of the new species, G. × maximo-velutina, and two putative parental species. The morphological characteristics and illustrations of the species based on the holotype and other specimens from natural populations are provided together with photographs of the habitat.
