There are many beautiful volcano caves in Je-ju island which is biggest volcanic island in Korea. The typical volcano caves are ManJang-gul, HyupJe-gul and MiCheon-gul, etc. Among them the MiCheon-gul name is originated from the beautiful things of cave which were more than thousands in there. This MiCheon-gul cave has another feature in special. It is about a native plant bracken living among the various live creatures and plants in MiCheon-gul cave, however, it is growing contrary under the vertex of the cave grown at retro-gravity, as one of the famous things of the proud cave. Therefore, it was contemplated and investigated on the habitat of a mode of life and ecological adaptation on the native plant of bracken include the geomorphic and geographic features of the MiCheon-gul cave.

Distribution of Viola inconspicua is newly discovered in Korea. This species was collected from grassy fields and roadsides in Jeju-si and Seogwipo-si, Jejudo Island. V. inconspicua shares several characteristics (i.e., purple or pale purple flowers, triangular leaf blades, winged petioles, and a linear-lanceolate stipules) with the related species V. mandshurica and V. yedoensis. However, V. inconspicua can be easily distinguished from other species by the following characteristics: leaf base (cordate vs. truncate to attenuate), and spur (short, 2-4 mm long vs. longer, 5-8 mm long). Here, we describe and illustrate of V. inconspicua. In addition, the identification key to allied species, photographs in its habitat, distribution, ecology, and phenology are provided as well. The Korean name for the species is given as 'Hwa-sal-ip-je-bi-kkot', considering the shape of its leaves.

The International Committee for Taxonomy of Viruses (ICTV), which was formed over 30 years ago, aims to develop a single, universal taxonomic scheme for all viruses or, in other words, "the classification of viruses and the assignment of names to taxa". Plant Virus taxonomy is in charge of Plant Virus Subcommittee, a substructure of the ICTV. The ICTV has been most successfully pursuing that aim and its mammoth 'Seventh Report' records details of the names it has collated and approved, and of the classification, it has devised. The current 7th ICTV report published in 2000 contains plant viruses of 951 species in 79 genera in 17 families, though 24 of the 79 genera are floating genera, that is, they are not included in any established families. Proposed name of new or existing viruses are vote for the accepted taxonomic proposals by ICTV Executive Committee meeting. The approved results have been published as the ICTV reports providing standard names and taxa of viruses all over the world. A number of new plant viruses have been identified or reclassified in the genus or species level, and new genera and families have been proposed.(중략)

We found Diplachne fusca subsp. uninervia (J. Presl) P.M. Peterson & N. Snow, an unrecorded alien plant, in Gimpo-si, Gyeonggi-do and Ganghwa-gun, Incheon Metropolitan City. Diplachne fusca subsp. uninervia is native to North America (the USA and Mexico), Central America (Belize, Costa Rica, Honduras, and Nicaragua), the Caribbean (the Bahamas, Cuba, Jamaica, and Puerto Rico), and South America (Venezuela, Brazil, Bolivia, Ecuador, Peru, Argentina, Chile, Paraguay, and Uruguay). It is reported as an invasive species worldwide. Diplachne fusca subsp. uninervia is closely related to D. fusca subsp. fascicularis (Lam.) P.M. Peterson & N. Snow (Gaet-deu-reong-sae in Korean), an invasive species in Korea, and both are infraspecific taxa of the species D. fusca. Diplachne fusca subsp. uninervia is distinguished from D. fusca subsp. fascicularis by the small size of its spikelets, glumes, and lemmas, with apex awnless. Its common name is "Jom-gaet-deu-reong-sae" based on the short spikelets. We found that D. fusca (≡Leptochloa fusca), previously known as "Gaet-deu-reong-sae", was misapplied. It is morphologically different from D. fusca subsp. fascicularis. Therefore, we changed the scientific name of Gaet-deu-reong-sae from D. fusca (≡L. fusca) to D. fusca subsp. fascicularis based on the type specimens, original descriptions, and recent studies.

The nation-wide medicinal plants list is prepared on the basis of the collected plant samples from 22 places of 9 regions where the authors possiblely surveyed and the references on field survey reported by others. No one has reported this kind of list before and the Engler's classification system is applied in this list instead of the previously applied Nakai's classification system. And also Korean name, occurrence, distribution, medicinal part, and name of crude drugs are described in the list. According to the results of this study, the number of the natural and cultivated medicinal plants in Korea are 950 kinds presently; i.e., 719 species, 1 subspecies, 209 varieties, 1 subvariety and 20 formas which belong to 142 families and 437 genera. Out of the 950 medicinal plants, cryptogamae are 22, herbs 550 and woodies are 278. The usual common drugs are 284 kinds and the allied plants are estimated 160 kinds. And there are some folk medicines and un-utillized medicinal plants.

The Korean name "Bizooki" tree was named by the shape of winter bud which is like a slim bow. There are four scientific names in the tree which are Cleyera japonica Thunberg, Cleyera ochnacea DC, Sakakia ochnacea Nakai, and Ternstroemia gymnanthera. And the English name are Japanese Ternstroemia and Japanese Cleyera. "Bizooki" tree has planted at Buddhist temples in Japan for the ritual. The best result of stem cutting in "Bizooki" tree, 100 percent of rooting, could be accomplished in July when cuttings were done on the mixture-soil containing the same rates by volume of vermiculite, peatmoss and perlite with cuts processed with IBA 1,000 mg/l under the circumstances that 70% of shade, plastic mulching, and mist were conditioned.

Objectives : The purpose of this study is correct the scientific name of Aquilariae Lignum in Korean Herbal Pharmacoepia. Methods : The production areas of Aquilariae Lignum and its trading status with China in Chinese history, Sanscrit-Chinese Translation Sutra, Naming year and the discovered district in main Aquilaria spp., Several nation's Pharmacoepia, The Plant List(TPL), Convention on International Trade in Endangered Species of Wild fauna and flora(CITES) and The International Union for Conservation of Nature(IUCN) were cross-checked. Results : The records in the Jiaozhouyiwuzhi written in the early 2nd century said that Aquilariae Lignum was produced in Vietnam. NanfangCaomuZhuang written in 304 said that Agarwood in Vietnam had white flowers. Vietnam had led production and trading of Aquilariae Lignum until Qing Dynasty. Aquilariae Lignum from Malaysia and Indonesia was not traded with China. In Sanscrit-Chinese Translation Sutra, India Aquilariae Lignum was translated as Vietnam Aquilariae Lignum. Aquilaria malaccensis was discovered from Malay-Peninsular in 1783, and has green or dirty yellow flowers. A. agallocha from North-Eastern India in 1814, white flowers. A. crasssna from Vietnam in 1914, white flowers. A. crassna is different from A. malaccensis in several ways, such as flower, fruit, seed and disribution. In several Nation's Pharmacoepia, A. crassna was a synonym of A. agallocha. But in TPL, CITES and IUCN, A. malaccensis was an accepted name, and A. agallocha was a synonym of A. malaccensis. Conclusions : These results show that the original species of Aquilariae Lignum in Korea Herbal Pharmacoepia should be reversed from A. agallocha to A. crassna Pierre ex Lacomte.

Objectives : Herbal medicines were used a lot in the Northeast Asia, traditionally. However, the pharmacopoeia standards in South Korea, China, Japan, Taiwan, and North Korea including many other Asia are different and cause confusion. If the origins are not belonging to same genus, it should be careful to distinguish. In this study, herbal medicines in the pharmacopoeia were analyzed for different genus of origins in order to identify the disruptive items for each country. Methods : The scientific names of herbal medicines (plant based) was analyzed origins from Pharmacopoeias of Republic of Korea, People's Republic of China, Japan, Taiwan, and Democratic People's Republic of Korea. The origins specified differently were examined. Especially, the items which have different genus were analyzed in detail and confirmed for correct scientific name. Results : The analyzed herbal medicines in Pharmacopoeia were all 753 items. 320 items were in only one country's Pharmacopoeia. 237 items were in more than two countries' Pharmacopoeia, but their origins were same on each other. The items which have different genus were 35 items. Conclusions : In general, species belonging to the same genus have similar ecological, morphological, and pharmacological activity. However, species with different genus may have different medicinal ingredients and pharmacological activity. Thus, the items which have same name but different genus are required to analyze for comparison of pharmacological activity. Also, other species belonging to the different genus should be used for different items.

Of the vast number of plant taxa in the world, the wood is one of the most useful resources. It is important to identify the fibers of wood and pulp for the plant taxonomy and for the uses, but we do not have enough information on them, on them, especially for the computerizd data. The fiber identification is one of the difficult tasks. In addition to the plant taxonomy and the fiber-using industries, such identification is also important in many other fields, including education. document examiners, etc. For these purpose, the fibers should be exactly distinguished. The TISS system I have programed to identify various woods would also be useful in the identification of fibers by the genus and species in the features of unknown samples and in searching the features of a species based on its scientific name. Such searching programs are being developed in many other countries with a view to searching for the species name by using the features of the cells of the woody materials. With the survey of all the available literature, the features of the fibers of 124 species both of softwood and hardwood were examined under the electron and optical microscopies. Each species were coded and carded by the feature, and the databases were built. The microscopic were inputted into a personal computer program called and by a slide film scanner. The new computer program called TISS 2 was developed using C computer language. Korean language fonts were added to the TISS 2. The TISS 2 can be in adding and searching a image of fiber features both of a known fiber and an unknown fiber. The databases were corded for the DELTA system with was developed by Dallwitz and Paine in Australia, 1986.

Two unrecorded species (Sceptridium atrovirens and S. microphyllum), previously known only in Japan, were found in a forest in Dosun-dong, Seogwipo-si, Jeju-do for the first time in Korea. S. atrovirens was distinguished from other related species of the genus Sceptridium in Korea by having the thickest rhizome and root, irregularly crenulate or roughly serrate, and a shorter sporophore blade. The local name was newly given as 'Sup-go-sa-ri-sam' for the species, denoting the habitat. S. microphyllum was distinguished by having the smallest plant height, compact sterile blades, and partly lateritious tropophyll in winter. The local name was newly given as 'Aegi-go-sa-ri-sam' for species, meaning of a small size. To reveal the interspecific relationships within the genus Sceptridium in Korea, cladistic analysis was performed for 27 morphological characteristics. The morphological characteristics and illustrations of the two taxa, as well as photographs at the habitat, are provided with a taxonomic key to the species of Sceptridium in Korea.
