Records found on labels of specimens deposited at University of Tokyo herbarium (TI) and references about Japanese naturalist, Tamezo Mori (1884-1964) were assembled to produce collector's itineraries from 1909 to 1916 in Korea. Mori collected large numbers of botanical specimens from different parts of the country. In August 1911 and 1912, Mori conducted botanical collections in Jeju and southern parts of Korean Peninsula. In 1913 major collections in North Korea by Mori took place in Mt. Baekdusan, Hamkyongnam-do. Following this exploration, in August 1916 Mori conducted another major collections in Pyeongannam-do and Hamgyeongnam-do. It is estimated that approximately 966 Korean specimens collected by Mori are currently held within the collections of The University of Tokyo herbarium (TI). Significantly these holdings also contain 46 type specimens (11 holotypes, 23 syntypes and 12 paratypes).

An unrecorded species, Carex benkei T. Shimizu, was found in Is. Jaewondo, Jaewon-ri, Imja-myeon, Sinan-gun, Jeollanam-do and Dongbaik-dongsan, Seonheul-ri, Jocheon-eup, Jeju-si, Is. Jeju-do, South Korea. C. benkei is closely related to C. transversa Boott and C. brownii Tuck., and C. benkei is distingushied from the pistillate scales length, excluding the awn, similar to the achene and the beak of the achene with an annular appendage. A new Korean name, 'Gin-Hwa-Sal-Sa-Cho', was given based on its long pistillate scales excluding the awn compared with Carex transversa Boott. We provide here its redescription, illustrations, photographs, and a key to species of the sect. Confertiflorae Franch. ex Ohwi.

This study aims to define the phylogenetic relationship within Korean section sabina and find molecular markers which resolve the phylogenetic relationship in genus Juniperus and section sabina. cpDNA matK and psbA-trnH were used as molecular markers. The combined analyses of two genes suggested that section sabina was a clade supported by 100% BP. The relationships of [J. chinensis var. sargentii+J. davurica] clade and [J. chinensis var. chinensis+J. chinensis var. procumbens+J. chinensis var. horizontalis] clade were supported by 91% BP and 100% BP, respectively. Thus, the classification of Korean section sabina would be appropriate at follows, (1) J. chinensis var. sargentii+J. davurica, and (2) J. chinensis var. chinensis+J. chinensis var. procumbens According to the results of separate analyses, matK seems to work better resolving power to clarify the phylogenetic ambiguity in Juniperus and section sabina than psbA-trnH.

A new leaf variegated cultvar 'White Edge' was developed by ethyle methane sulfonate(EMS) treatment on seed of Hosta minor. Among induced leaf variegated plant, some with white color on the edge of the leaves was selected. They were cultivated via vegetative propagation. 'White Edge' was finally selected through the test of characteristics from 2003 to 2005. Assessment of botanical characteristics was conducted for three years. The major characteristic of these cultivar is that they maintain uniformly all year round. 'White Edge'(Grant No.1880) was registered to the Korea Seed and Variety Service(KSVS) for commercialization in 2007. These cultivar are useful as materials for pot or as ground cover plants.

We report Polygonum plebeium R.Br. (Polygonaceae) as an unrecorded species from the Geumgang River, Buyeo-gun; Galmae-dong, Guri-si; the Chungju Reservoir, Jecheon-si; the Daecheong Reservoir, Okcheon-gun; and the Daecheong Reservoir, Daejeon, in Korea. It is distinguished from P. aviculare by pedicels that articulate in the middle and by its smooth and shiny achenes. The new Korean name, 'Ae-Gi-Ma-Di-Pul', is given considering the small-sized plant. In this study, a description and illustrations of the species and photos of the habitat are provided.

To identify the flora of the vascular plant on Chujado Island in Chuja-myeon, Jeju-si, Jeju Province, Korea, eleven field surveys were conducted between April to September of 2013 and from May to September of 2018. The results of the surveys identified 558 taxa, with 97 families, 311 genera, 481 species, two subspecies, 65 varieties, and ten forms of vascular plants on Chujado Island. Of the 558 taxa identified, seven were endemic species and eight were rare plants according to the Korea Forest Service. Furthermore, 109 of the taxa identified were from floristic environments, while 62 were considered to be naturalized plants, with three of these considered to be invasive and causes of ecosystem disturbances. The highest degree of similarity among the plants from seven sites adjacent to Chujado Island was found on Saengil Island, at 51.7%.

For the variant identification of Korean dogwood, Cornus kousa Buerg., we investigated useful genetic marker using the ISSR primer. The overall amplicons was 58 in six primers and the mean number of amplicons per primer was 9.67. The UPGMA dendrogram based on the genetic distance showed two major clusters composed of pink-bracted and white-bracted groups respectively. And white-bracted group was divided to two groups, island and inland groups. This result showed that ISSR analysis provides useful markers for the variant identification even in the seedling or young tree of Cornus kousa, especially pink-bracted individuals of Isl. Oenaro.

In this study, we 1) identified the damaged areas along the south limit line (SLL) of the demilitarized zone (DMZ) by the military's 'DMZ barren land campaign', and 2) categorized the identified damaged areas into a few ecological types. Using high-resolution satellite images, we delineated the total damaged areas to be 1,183.2 ha, which accounted for 50.1% of the 100-m northern buffer regions from the SLL. Of the total damaged areas, 16% were severely damaged, i.e., they had been damaged until recently and so remained barren without vegetation cover. In other areas, the levels of damage were either moderate (59.9%) or slight (24.1%), due to natural succession that turned those areas to grassland or forest. Using satellite image-derived land cover maps and climatic and topographic data, we categorized the damaged areas into seven types: lowland grassland (19.8%), western lowland forest (21.4%), low-altitude forest (25.5%), mid-altitude forest (18.4%), high-altitude forest (6.8%), vicinity in east coast (7.9%), and waterbody (0.2%). These types can be used to identify proper measures to restore ecosystems in the DMZ for now and after Korean reunification.

To provide the basic information on the excavation, conservation, and systematic management plan for preservation of valuable forested wetlands, a field survey was analyzed at public and private forests in Daegu city, 2010. The expected points of FGIS were identified, and buffer zones for the protection of forested wetlands were derived. According to the results from the 11 points of forested wetland, the flora of wetlands in Daegu city were consisted of a total of 169 taxa; 63 families, 131 genera, 148 species, 2 subspecies, 14 varieties, and 5 forms. The species diversity of shrubs in forest wetlands was highest at 1.560, and the evenness was highest in shrub trees at 0.913. Considering the type of wetland, topography, etc., the buffer zone was set at 20~50m from the core area boundary.

Cyrtomium yamamotoi Tagawa is an unrecorded species of perennial Pteridophyta that belongs to the genus Cyrtomium of Dryopteriaceae. It is known as native to Taiwan, China and Japan, but we found it in Jeju-si, Jeju-do and Haenam-gun, Jeollanam-do, Republic of Korea in 2018. This species is very similar to C. fortunei J.Sm. having characters such as 1 pinnate compound leaves, globular indusium, but distinguished from the latter by its lanceolate or lanceolate-ovate shaped lateral pinnates of less than 12 pairs, bicolor indusium with dark brown or blackish in center, and margin incised teeth. Here, we provide its description, photographs and a key of related taxa in Korea.
