A history of bryological studies on the Korean Peninsula
Lee, Ji-Yeon ; Choi, Byoung-Hee ;
Korean Journal of Plant Taxonomy, volume 42, issue 2, 2012, Pages 109~115
DOI : 10.11110/kjpt.2012.42.2.109
This study introduces the bryological history and literature of the Korean Peninsula. The French missionary Urban Faurie was the first person to collect Korean bryophytes at the beginning of the 20th century. Most of his bryophyte collections from Korea were studied and recorded by Jules Cardot (for mosses) and by Franz Stephani (for liverworts). Japanese studies of Korean bryophytes were described in chronological order. Hong Won Shic and Choe Du Mun carried out an inventory and flora research on bryophytes in South Korea. The most recent bryological studies of North Korea are also reviewed here as a reference.

The distribution, vegetation characteristics and an assessment of the conservation status of the Korea endemic species Coreanomecon hylomeconoides Nakai were investigated to collect biological basic data to formulate a conservation strategy. According to the distribution map of C. hylomeconoides based on the literature, specimen information, and local field surveys, natural populations of C. hylomeconoides are intensively distributed in the Southern regions of the peninsula, around Gyeongsangnam-do and Jeollanan-do. C. hylomeconoides was distributed in the middle and low slope adjacent to a valley. The altitude ranged from 227 m to 744 m, with inclinations of
. As a result of a vegetation survey within natural populations, a total of 238 taxa were identified from 29 quadrates in 8 natural populations. The importance value of C. hylomeconoides is 25.34% based on the coverage and frequency of the herbaceous layer with in the populations. The species diversity of the occurrence of the species in 8 natural populations was 1.52, while the averages of species evenness and the dominance values were calculated to be 0.83 and 0.17, respectively. As a result of assessing the conservation status through IUCN Red List criteria, C. hylomeconoides was evaluated as Near Threatened (NT). Conservation strategies are also discussed for the sustainable conservation of C. hylomeconoides.
Numerical taxonomic study of Najas L. (Hydrocharitaceae) in Korea
Na, Hye Ryun ; Choi, Hong-Keun ;
Korean Journal of Plant Taxonomy, volume 42, issue 2, 2012, Pages 126~140
DOI : 10.11110/kjpt.2012.42.2.126
We conducted principal component analyses using the thirty two quantitative characteristics of Najas from South Korea to examine the morphological variation and diagnostic characteristics. As a result of our investigation and the morphometric analyses, each taxon could be identified using the leaf width, shape of the leaf sheath, number of teeth on the leaf margin, number of anther cells, number of areoles in each longitudinal row of seeds, and the ratio of the areole width to the length. Dioecious Najas marina was clearly distinguished from the other monoecious taxa (N. graminea, N. gracillima, N. minor, N. oguraensis, and N. orientalis) by the larger size of the stem, the leaf, the flower and the fruit. The monoecious taxa could be identified using vegetative characteristics except for N. minor and N. oguraensis, which were distinct from each other according to the locule number in the staminate flower.
Reconsideration of the taxonomic characteristics of Callicarpa japonica Thunb. and C. dichotoma (Lour.) K. Koch (Verbenaceae) in Korea
Yoon, Min-Ji ; Choi, Bo-Kyung ; Hong, Suk-Pyo ;
Korean Journal of Plant Taxonomy, volume 42, issue 2, 2012, Pages 141~149
DOI : 10.11110/kjpt.2012.42.2.141
To clarify some ambiguous diagnostic characters of Callicarpa japonica Thunb. and Callicarpa dichotoma (Lour.) K. Koch in Korea (Verbenaceae), the external morphology and micromorphology (leaf, anther, pollen, fruit, in particular endocarp surface and structure) of two taxa are studied and described in detail. It is confirmed that the following characteristics (e.g., the stem outline in a cross-section, the bud shape and length, the corolla tube length and the lobe length, the pattern of the anther dehiscence and length, and the endocarp morphology) are useful for distinguishing these two taxa. In particular, following three characteristics are most useful for an identification: (1) the corolla tube length of C. japonica (2.5-4.6 mm) is longer than that of C. dichotoma (0.7-1.0 mm); (2) the anther is dehiscing by an apical pore at the anthesis of C. japonica, while it is opening by a long fissure from the apex to the base in C. dichotoma; and (3) the edge of the endocarp (lateral view) in C. japonica is concave, while in C. dichotoma it is shown to be flat. On the other hand, the teeth state on the leaf margin and the position of inflorescence are not good diagnostic characteristics for identification. Additionally, the keys for all known Callicarpa taxa in Korea are provided.

While preparing a floristic study of Korean hepatics, we discovered the six unrecorded species of Lejeuneaceae from Mt. Seolak, Mt. Gaya, Geojedo, Wando and Gageodo. Archilejeunea kiushiana, Drepanolejeunea angustifolia, Lejeunea aquatica, Lejeunea otiana, Leucolejeunea japonica, and Spruceanthus semirepandus, are reported here. A. kiushiana was characterized by unlobed underleaves, homogeneous oil-bodies, and four to six perianth-keels. D. angustifolia is similar to D. ternatensis, but it differs in the dorsal margin of the leaf-lobe, which is entire or denticulate, spines never present, and leaf cells smooth or with minute dorsal bulging. L. aquatica is similar to L. japonica in that it has a wider and similar shape (wider than long) of its underleaves and has homogeneous oil-bodies. The former, however, has minute leaf-lobules (5-15 cells), 1/10 to 1/5 the length of the leaf-lobe, versus leaf-lobules 1/4 to 1/3 the length of the leaf-lobe. L. otiana is similar to L. kodamae in that it has a large and acute first tooth of the leaf-lobule but differs in having plain leaf-lobules obliquely quadrate and an indistinct second tooth. Drepanolejeunea (Spruce) Schiffn. is widely distributed in tropical and subtropical regions (Mizutani, 1961). L. japonica is characterized by entire underleaves; one large, coarsely segmented oil-body per leaf cell; and a large second tooth of the leaf lobule, two to six cells long, and two to three cells wide at the base. S. semirepandus is widely distributed in tropical and subtropical regions in Asia. This species is characterized by small homogeneous and numerous oil-bodies, up to 10 smooth perianthkeels, and leaf-lobe acute at the apex.

Leontopodium seorakensis (Asteraceae), a new species from Mt. Seorak National Park in central Korea is described and illustrated. Its taxonomic history, distribution, habitats, and diagnostic characteristics are discussed and contrasted with those of the closely related L. japonicum Miquel and L. leiolepis Nakai.
Taxonomic identity of Gang-hwa-yak-ssuk
Park, Myung Soon ; Nam, Bo Mi ; Chung, Gyu Young ;
Korean Journal of Plant Taxonomy, volume 42, issue 2, 2012, Pages 161~166
DOI : 10.11110/kjpt.2012.42.2.161
Aiming to determine the taxonomic identity of Gang-hwa-yak-ssuk as a cultivated plant, this study analyzes ITS sequences and compares their external morphologies with the genus Artemisia, which have a similar external morphology. Thus far, we have considered A. indica as the original plant of Gang-hwa-yak-ssuk, but Gang-hwa-yak-ssuk is better grouped with A. argyi, not A. indica, for the following reasons: Gang-hwa-yak-ssuk has the same characteristics as A. argyi in terms of the natural habitat, in that it is 1-bipinnately cleft or parted in the external morphology of its leaves, and because the white glandular trichome is distributed on the adaxial surface. This is in addition to the result of ITS sequence analysis. Therefore, we can define Gang-hwa-yak-ssuk as a cultivated plant that originates from A. argyi and not A. indica.

During the course of the execution of the project entitled Distribution Research of Rare Plants, we found the habitats of two rare ferns with obscure and/or extremely restricted distribution ranges, as previously unreported habitats. A subantarctic fern reported on Hamgyeong-do and Gangwon-do, Dryopteris coreano-montana Nakai, was found on Mt. Ibam in Jangseong-gun, Jeollanam-do. A subtropical fern reported south of Jeju-do, Dryopteris decipiens (Hook.) Kuntze, was newly found on Mt. Cheongwan of Jangheung-gun in Jeollanam-do.

Two naturalized species, Chaerophyllum tainturieri Hook. (Umbelliferae) and Barbarea verna (Mill.) Asch. (Cruciferae) were newly reported from South Korea. C. tainturieri., `Jeon-Ho-A-Jae-Bi`, was found at World Cup park in Sangam-dong, Mapo-gu, in Seoul, and the genus Chaerophyllum is reported for the first time from South Korea in the present paper. It is distinguished from the genus Sphallerocarpus by having cylindrical fruit, and each furrow with one vitta. B. verna, `Bom-Na-Do-Naeng-I`, was found on a riverside area of Suyeong River, Geumsa-dong, in Busan. It can be distinguished from B. orthoceras by silique 4-8 mm long , seeds 1-2 mm long, and basal rosette leaves with a 4-11 large pairs of lateral lobes.

DOI : 10.11110/kjpt.2012.42.2.178
We report a newly naturalized species of the genus Bidens L. (Asteraceae) in Korea, specifically Bidens subalternans DC. var. subalternans. This naturalized plant was discovered Geumjung-gu in Busan; Gyeongsan-si, Jillyang-eup in Gyeongbuk-do; and in Buk-gu in Daegu. Bidens subalternans var. subalternans is distinguishable from other Bidens in Korea by the following combination of characteristics: an odd-pinnate leaf, deeply lobed, narrow lanceolate, four lobes in the corolla, an oblong achene shape. This taxon is termed `Wang-do-kka-bi-ba-neul` as a common Korean name based on its large size (in particular, the size of leaf). The key for all taxa of the genus Bidens in Korea is also provided here.
