A new taxon of Ilex is described from Wando Island, Province Jeonnam, Korea. Ilex x wandoensis C. F. Miller & M. Kim hybrid nov. originates from the natural hybridization of the parent species, I. cornuta Thunb. and I. integra Thunb. Leaves of the new taxon have smooth, spinose margins, a condition that is intermediate between the twisted, spinose leaf margins of I. cornuta and the smooth, entire margins of I. integra. The new hybrid species shares several characters with its two parents, including evergreen leaves, dioecy, and red drupes.

We performed the numerical analyses of thirty two morphological characters for twenty four populations of eight Korean Ilex L. taxa. Principal component analyses showed that the first three principal components were related to the total covariance by 67.0%, and the proportions of PCl, PC2 and PC3 were 31.5%, 21.1%, and 14.4%, respectively. And the closely related characteristics to the PCl, PC2 and PC3 were some reproductive characters such as the morphology of sepal, petal, anther, pistil and fruits and vegetative characters such as the morphology of petiol and leaf margin, the trichomes on the twigs, the leaf duration. From the two dimensional plottings by the eigenvalues of PCl, PC2 and PC3, six grouped were clustered as Ilex integra, I cornuta, I x wandoensis, I. rotunda, I. macropoda and I. macropoda for. pseudomacropoda, I. crenata and I. crenata var. microphilla. The numerical analysis was useful for the taxonomy of Korean Ilex because it clearly seperated the populations of taxa included in this study. The identification key was provided with the diagnostic characters.
