  • Morphological characters of section Acutae of the genus Carex (Cyperaceae) were reexamined. The epidermal patterns of perigynium, achene and leaf were investigated using by a scanning electron microscope (SEM) and a light microscope (LM). Morphological characters such as length and width of stem. leaf, bract, spike, scale, perigynium and achene, and shape of cross-sectioned stem, spike, scale, apex of scale, perigynium, beak of perigynium and achene, and epidermal pattern of perigynium, achene and leaf (shape of fundamental epidermal cell and cell wall, type of silica body, shape of beak epidermal cell and cell wall in perigynium, subsidiary cell shape. size and frequency of stomatal complex of leaf were useful for the identification of the observed 11 taxa. C. cinerascens, C. heterolepis and C. forficula have been confused due to similar morphological characters. C. cinerascens, C. heterolepis and C. forficula were distinct. however with respect to from width of leaf, shpae of scale, apex of scale, perigynium, beak of perigynium, and epidermal patterns of achene and leaf.

  • A survey of syntaxa of vegetation of evergreen broad-leaved forests in Korea, class Camellietea japonicae is presented. 399 releve's were arranged two phytosociological tables, each representing an alliance. A synoptic table comprising all alliances is presented. The vegetation of evergreen broad-leaved forests is divided into three alliances including twelve new associations: (1) Querco - Castanopsion all. nov., split into four associations, Castanopsietum sieboldii, Quercetum acutae, Quercetum myrsinaefoliae and Litseetum japonicae; (2) Machilo-Camellion all. nov., separate into ten associations, Machiletum thunbergii, Pittosporetum tobirae, Aucubetum japonicae, Neolitsetum sericeae, Euryetum emarginatae, Elaeagnetum macrophyllae, Camellietum japonicae, Theo-Camellietom japonicae, Raphiolepietum umbellatae and Daphniphylletum macropodae; (3) Dendropanaco-Castanopsion sieboldii including one association, Hosto minoris-Castanopsietum sieboldii. The alliances are floristically and ecologically characterized and their distribution in Korea shown on the map.

  • The Camellia japonica vegetation in the Korean Peninsula was investigated by the methology of the Z-M school. The synthesis table of Camellion japonicae were arranged for association classification from 263 quadrats. The vegetation of Camellia japonica forest, classfied as an alliance includes nine new associations : Camellietum japonicae typicum Jin et Kim 2005, Machilo thunbergii-Camellietum japonicae Jin et Kim 2005, Pino thunbergii-Camellietum japonicae Jin et Kim 2005, Castanopo cuspidatae var. sieboldii-Camellietum japonicae Jin et Kim 2005, Lito japonicae-Camellietum japonicae Jin et Kim 2005, Castnnopo cuspidatae var. thunbergii-Camellietum japonicae Jin et Kim 2005, Querco acutae-Camellietum japonicae Jin et Kim 2005, Neolito sericae-Camellietum japonicae Jin et Kim 2005, Cinnamomo japonicae-Camellietum Japonirae Jin et Kim 2005.
