To examine the differentiation and transition of vascular system in Prunus davidiana FR., the mature embyro and developing seedlings were embedded in paraplast and treated by clearing method. In mature embryo, the procambium was connected with the epicotyl-hypocotyl-radicle axis and cotyledons, whereas protophloem and protoxylem were restricted primarily to the mid-vein and two lateral veins of the cotyledonary base. With the onset of germination, protophloem and protoxylem were differentiated both acropetally and basipetally from the cotyledonary base. The first and second leaf traces appeared in the cotyledonary node, and then differentiated bidirectionally toward the epicotyl and the root tip. The 3rd to 6th leaf traces were connected with the cotyledonary traces in hypocotyl. At the part of the root tip, the xylem was a diarch. As the first and second leaf traces were superimposed at the middle part of the root, the diarch xylem was changed to a tetrarch. As the cotyledonary traces were diverged below the root base, the tetrarch xylem was changed to an octarch. It was suggested that the vascular system of the epicotyl might be superimposed on that of the cotyledon-hypocotyl-root during the formation of the primary vascular system of Prunus davidiana.

This study was to establish the floristic composition of vascular plants of Mt. Hwangjang (1,077.3m). Floristic composition of vascular plants were conducted during April 2006${\sim}$August 2007. Vascular plants were composed of 97 families, 257 genera, 357 species, 5 subspecies, 42 varieties and 9 formae, totaling 413 taxa. Among the investigated resources plants, 6 taxa were Korean endemic species. The special plants based on floral region by Ministry of Environment (2006) were 55 taxa. A naturalized plants were 15 species, correspond to 5.2% of totaling 290 species (Kim and Lee, 2006) appeared in South Korea.

Specific plant species by floral region were total 40 taxa; 2 taxa(Crypsinus hastatus, Prunus yedoensis) in class V, Patrinia rupestris in class IV, 6 taxa(Elymus mollis, Carex laticeps, Poncirus trifoliata, Melia azedarach var. japonica, Koelreuteria paniculata, Crepiastrum lanceolatum) in class III, Cirsium schantarense in class II, 30 taxa(Lygodium japonicum, Pteris multifida, Phacelurus latifolius, Asparagus cochinchinensis, Ficus erecta, Machilus thunbergii, Zanthoxylum planispinum, Euphorbia esula, Mallotus japonicus, Cayratia japonica, Camellia japonica, Glehnia littoralis, Lysimachia fortunei, Messerschmidia sibirica, Ixeris repens etc.) in class I. The naturalized plants in this site were 14 families, 34 genera, 41 species, 1 varieties, 42 taxa and naturalization rate was 20.3% of all 207 taxa vascular plants. Based on the list of the rare plants by the Forest Research Institute, 2 taxa were recorded in the studied areas; Phacelurus latifolius, Crypsinus hastatus and based on the list of Korean endemic plants, 7 taxa were recorded; Populus tomentiglandulosa, Filipendula glaberrima, Prunus yedoensis, Forsythia koreana, Paulownia coreana, Weigela subsessilis, Carpinus coreana. So, wild plants disturbing ecosystem like Solanum carolinense and Ambrosia artemisiifolia var. elatior have been increasing, it needs continuing control and conservation measures on the plant ecosystem.

This study was carried out to investigate the flora of Is. Gageo (Jeollanam-do). The vascular plants were collected 13 times (from June 2008 to September 2011), and 465 taxa in total were identified, including 112 families, 301 genera, 402 species, 3 subspecies, 49 varieties, 9 forms and 2 hybrids. 171 taxa were first records for the region. Among them were seven taxa of Korean endemic plants and the Ministry of Environment-designated plants, which should be protected by the wildlife protection law, were identified as three taxa. There were 54 taxa of the flora with the levels III, IV, V in the floristic indicator plants which was designated by Ministry of Environment. The naturalized plants were identified as 29 taxa, and their naturalization ratio and urban index were found to be 6.2% and 9.0% respectively. There existed many kinds of plants resources having conservational value like $Loxogramme$ $salicifolia$, $Sarcandra$ $glabra$, $Osmanthus$ $insularis$, $Saussurea$ $polylepis$, $Carex$ $ligulata$ var. $austrokoreensis$, $Hosta$ $jonesii$, $Cyrtosia$ $septentrionalis$, etc., in this area. As therefore clear that appropriate plans to conserve the natural habitat of Is. Gageo must be made immediately.

Distributional pattern of vascular plant species in terms of species-area relationship and distances from their species pool on the 53 islands selected in the South Korea were studied. From the relationship between vascular plant species and area the equation of species-area was established as the follow: S=cA2 c=135.52 z=0.226 S; number of species A; area of island In the equation the Z value 0.226 is lower than those of any other localities reported in the world. Z value increased with the increasing distance from the species pool while C value decreased. The relationships of Z and/or C and distance from species pool, D, were established; Z=0.002D+0.176 C=-39.5logD+178.5 The tendency of common species decrease of them with the increasing islands was fifted to the Fisher's logarithm series. Common species 50% above was 39 species, including the most common species, Pinus thunbergii. Quotient of Similarity value by Sorensen (1948) on common species was relatively low i.e. 0.27∼0.47. It is noticeable for their vegetation conditions that the naturalized plant as a indicator of disturbance, for example Erigeron canadensis, was widely distributed.
