Objectives : The purpose of this study is to analyze the origin plants, the habitat and the characteristics of the origin-plants of the medicine herbs belong to Araceae. Methods : To achieve the purpose of this study 48 bibliographies about 4 kinds of herbs belong to Araceae were examined. The examination was focused on the origin plants, habitat, the efficacy. Standing on this analysis the list and characteristics of the origin-plants were presented. Results : The results indicated that 1. In the original plants of 4 kinds of herbs, there were 27 species of scientific name totally, 25 species belonged to Araceae, and 2 species didn't. The origin plants of Pinelliae rhizoma were 3 species of different family plant, 16 species for Arisaematis Rhizoma, 2 species for Typhoni Rhizoma, and 6 species for Acori Graminei Rhizoma. 2. In the view of its authenticity, there was one kind of genuine species, 2 species of substitutes in the origin plants of Pinelliae Rhizoma, 14 kinds of genuine species, 2 species of substitutes in the origin plants of Arisaematis Rhizoma, and Whole origin plants of Typhoni Rhizoma, Acori Graminei Rhizoma were genuine species. 3. According to the habitat, there were 15 species distributed in Korea, China and so on. And 16 species were distributed in Korea, 25 species were of foreign origin. 1 species was unknown. 4. The each efficacy of origin plants were reported in the main subject Conclusions : Among the 4 medicinal herbs in the commonly using family Araceae, there were 27 origin plants(25 species belong to Araceae, and 2 species doesn't), so the number of origin plants are almost 6.75 times compared with the cases of the herbal name. Also, according to the habitat, approximately 59.3% of origin plants were producted in Korea, and approximately 92.6% of origin plants were of foreign origin.

We found that the vascular plants in this region comprised 424 taxa belong to 102 families, 281 genera, 390 species, 5 subspecies, 26 varieties, and 3 forma. Five taxa of Korean endemic plants including Weigela subsessilis (Nakai) L.H.Bailey, Lespedeza maximowiczii var. tricolor (Nakai) Nakai, and Clematis trichotoma Nakai were collected. Two least concern (LC) taxa of rare plants (as designated by the Korea Forest Service) were collected: Hydrocharis dubia (Blume) Backer and Platycladus orientalis (L.) Franco. Ten the floristic regional indicator taxa from the third to the fifth grade were identified: two taxa belonged to grade IV, and eight taxa belonged to grade III. Twenty-four taxa of salt-tolerant plants, including Artemisia fukudo Makino, Carex rugulosa Kuk., and Suaeda glauca (Bunge) Bunge, as well as 44 taxa of aquatic plants, including Najas marina L., Nuphar oguraensis Miki, and Nymphoides indica (L.) Kuntze, were investigated in this region. Fifty-nine taxa of naturalized plants were recorded, among which the following six taxa were plants that caused ecosystem disturbance: Ambrosia artemisiifolia L., Humulus scandens (Lour.)

Tonggo-san(1066.5m) is located at 36° 53' 00" - 36" 55' 00" in latitude, at 129° 10' 30" - 129° 13' 00" in longitude and on Seo-myeon, Uljin-gun and Subi-myeon, Yeongyang-gun in Gyeongsangbuk-do. Tonggo-san shows the typical vegetation patterns including the middle area of temperate region of Korea represented by the secondary forests of Quercus mongolica and Q. dentata. There was no detailed result on the flora and vegetation of Tonggo-san until now. Therefore, we tried to discuss on the distribution and availability of vascular plants including economical plants. Also, we could discuss the especialized plants and their distributions according to the criteria by the Ministry of Environment. The results of plant collection and their investigation from April in 2001 to November in 2001 are as follows : The vascular plants consist of total 565 taxa; 17 forms, 82 varieties, 466 species, 297 genera, 94 families,37 orders, 4 classes, 2 subphyla. In this area, there were a lot of useful economic plants such as 232 taxa(41%) of edible source, 222 taxa(39％) of forage source, 183 taxa(32%) of medicinal source, and 72 taxa(12%) of ornamental source, 15 taxa(2.6%) timber source, 7 taxa(1.2%) industrial raw material source respectively. Among them, the Korean endemic plants were 22 taxa(3.9％ among total 565 taxa); 1 forms, 2 varieties, 19 species, 22 genera, 16 families. And rare and endangered plants was 1 taxa; Astragatus membranaceus. Also, the naturalized plants were 19 taxa(3.4% among total 565 taxa and 10.4% among the total naturalized plants in Korea).

(1) Plants in the crater of Halla-San (Mt. Halla), a conical volcano that originated in the Tertiary period, were studied on three different occasions; July 1937, July 1955, and August 1957, and noted 52 familites, 149 species. In the latest study undergone in 1957, the authors collected 108 species. Notable species among them are Geranium Shikokianum Matsum which has not been reported in Korea, Clematis Chiisanensis Nakai, Lactuca Chelidonifolia Makino, and Platanthera Maximowiczana Schelchter which have not been reported in Jeu-Do(Island) so far. (2) Plants in To-Do(Island), territorial island of Jeju-do, were also studied. The authors noted Canavalia lineata D.C.non-reported Species in Korea, usually distributed along Southern Honshu, Shikoku, and Kyushu of Japna, Ryukyu and Taiwan. The overfall flora of the island is composed of 30 families, 44 Species; 5 Species of wood plants and 39 species of herbs, and is mostly of littoral plants.

Species invasions have rapidly increased due to the substantial growth of global trade in the recent past. As the awareness of the negative effects on natural ecosystems derived from alien species has grown, many countries and lawmakers have enacted rules and policies on the conservation of indigenous plants. Unfortunately, in Korea, research on species invasion is seriously lacking despite the growing number of alien species. In the current study, we report alien plants that have intentionally and/or unintentionally been introduced in Korea and also presented a checklist of invasive plants found both in the literature and in field surveys. We reviewed all documented records of alien plants, i.e., scientific papers, illustrated books, and annual reports. We also categorized alien plants by origin, time of introduction, naturalization, and the rate of their spread. The results revealed that there are 619 alien plant taxa (96 families, 353 genera, 595 species, 6 subspecies, 11 varieties, 1 forma, and 6 hybrids) occurring in Korea. Among these, 30 taxa are archaeophytes (Arc.), 214 are potentially invasive plants (PIPs), and 375 are invasive alien plants (IAPs). In addition, IAP taxa consist of grades 5 (widespread, WS) to 1 (potential spread, PS) of alien plants according to the rate of spread in Korea. Our results suggested that the number of alien plants is likely to keep growing; thus, the distribution should be regularly monitored and the list of alien plants must be updated.
