  • 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.

  • This study was conducted to analysis the ecological characteristics of "Wando HolIy"$(llex{\times}wandoensis)$ which is expecting as a possible ornamental tree with its beautiful leaves, flowers and fruits, and to find special breeding material which have particular characteristics and also provide correct environmental information which are required for commercial cultivation. The hill of Galmoon-Ri, Gunoei-Myon, Jeonnam Province, Korea, were reported as a original habitat of native $llex{\times}wandoensis$. The investigation shows that soil pH of native habitat was 6.18, hardness was 2.39, humidity was 38.6%, direction of slope is SSW, and average inclination was $15^{\circ}. The vegetation around $I.{\times}wandoensis$ is occupied by trees like an Quercus variabilis, Q. serrata, Q. acuta and so on. These are mixed forest of deciduous trees. Tree height reached up to about 12m and its coverage is about 30%. Q. salicina, Camellia japonica, I. integra, Cryptomeria japonica account for sub-tree layer. Tree height is around 8m and coverage is about 20%. Shrub layer was taken by Viburnum furcatum, Callicarpa japonica, Styrax japonica, Eurya japonica, Lindera obtusiloba, Ligustrum japonicum, Smilax china, Cornus walteri etc. Tree height reaches around l.2m and coverage is around 20%. Herb layer includes Trachelospermum asiaticum var. intermedium, Cymbidium goeringii, Dryopteris bissetiana, Disporum viridescens, Disporum smilacinum, Sasa borealis var. gracilis etc. Trachelospermum asiaticum var. intermedium, which are observed in southern evergreen zone, are dominant and its coverage is around 20%. The native habitat was in spoiled condition because of artificial thin out.
