Aster altaicus var. uchiyamae, a Korean endemic plant, should be treated as a species rank because it is clearly distinguished from A. altaicus var. altaicus by the morphological characteristics of the plant habit, leaf width, and head size. Nevertheless, when A. altaicus var. uchiyamae was treated as a species rank, the epithet uchiyamae was unavailable in Aster owing to the earlier name A. uchiyamae, which was a replacement name for the illegitimate name A. depauperatus. Therefore, we propose A. danyangensis as a new replacement name for A. altaicus var. uchiyamae. The specific epithet danyangensis refers to the geographic location of Danyang-gun, where the species was discovered. We also designate the lectotype and isolectotype of A. danyangensis.
内山紫菀是韩国特有植物，在植物习性、叶宽、头大小等形态学特征上与紫菀有明显的区别，应作为种级来处理。然而，当altaicus var. uchiyamae被视为一个种级时，由于早期的名称a . uchiyamae是对非法名称a . depauperatus的替代名称，因此在Aster中无法获得uchiyamae这一称号。因此，我们建议丹阳a . danyangensis作为altaicus var. uchiyamae的新名称。“丹阳种”的特称是指丹阳郡发现该物种的地理位置。我们还指定了丹阳白杨的选异型和等异型。

Tordylium maximum L. (Apiaceae), native to south, south-central Europe and southwest Asia and a rare alien plant in northern Europe, was newly found in Jeollabuk-do in Korea. Tordylium is clearly distinguished from other genera by having radiating petals, filiform bracts, linear bractlets, stalked mericarps with minutely vesicular dorsal face or strigose hairs, and an annual habit. Tordylium maximum is different from other species of the genus by its mericarps with smooth margins and 10–16 rays not contracted in fruit. T. maximum grows on dry and sunny grasslands. Here, we report the first occurrence of the genus Tordylium represented by T. maximum in Korea and provide a precise description, illustration, photographs of the species, and a taxonomic key to allied taxa in Korea.

Polygonatum falcatum is a perennial herb distributed in East Asia. We determined the characteristics of the complete chloroplast genome in P. falcatum for the first time, with a de novo assembly strategy. The chloroplast genome was 154,579bp in length harboring 87 protein coding genes, 38 tRNA genes and eight rRNA genes. It exhibits typical quadripartite structure comprising a large single-copy (LSC) (83,528bp), a small single-copy (SSC) (18,457bp) and a pair of inverted repeats (IRs) (26,297bp). Phylogenetic analysis of 16 chloroplast genomes from Asparagaceae reveals that the genus Polygonatum is a monophyletic group and that P. falcatum is clustered together with the congener, P. odoratum.

A palynological study of genus Dioscorea L. in Korea was conducted to evaluate the taxonomic implications. As a result of confirming the palynological characteristics of seven taxa of Dioscorea L., including six that are distributed in Korea and D. tokoro found in Japan, sections or species were classified according to the characteristics, such as the number of apertures, the polar end shape, and exine sculpturing. Specifically, the exine sculptures of D. coreana and D. tokoro, erroneously known to be distributed in Korea, are distinguished. The change in the number of apertures is closely associated with microsporogenesis, and it can be presumed that disulcate pollen might have been derived from monosulcate pollen in Dioscorea.

Prunus subg. Cerasus is the most planted street and landscaping tree in South Korea, but it is difficult to identify species according to their macro-morphologies, leading to problems when attempting properly to manage species quantities. The purpose of this study is to understand the current status of plant types and species compositions in Bundang Central Park in Bundang-gu of Seongnam City and to discuss the necessity of the management of landscaping tree planting. In April of 2021, during the cherry blossom season, a total of 5,866 planted cherry trees were investigated within an area of 6 km2 of Bundang-gu in Seongnam City. As a result, 5,744 trees were sorted into eleven taxa, but the remaining 122 trees were not determined due to their complex morphologies. Prunus ×yedoensis Matsum. accounted for the highest proportion (52.1%), followed by P. serrulata Lindl. var. pubescens Nakai and P. jamasakura Siebold ex Koidz. P. ×nudiflora (Koehne) Koidz., a plant native to Jejudo Island, was not found in this survey. In order to help identify cherry trees based on micro-morphologies, an identification key was presented for the eleven taxa planted as major landscaping trees. It is known that cherry trees frequently form interspecific hybrids in nature. In order to prevent a loss of the genetic originality of native species due to hybridization and gene introgression from foreign cherry trees, it is necessary to manage planting species near the habitats of native taxa and track their origins.
李属subg。樱花是韩国种植最多的街道和景观树，但很难根据其宏观形态识别物种，导致在尝试适当管理物种数量时出现问题。本研究的目的是了解城南市盆唐区盆唐中央公园植物类型和物种组成的现状，并探讨园林绿化植树管理的必要性。在樱花盛开的2021年4月，在城南市盆唐区6平方公里的范围内，对5866棵种植的樱花树进行了调查。结果，5744棵树被划分为11个分类群，但其余122棵树由于其复杂的形态而未被确定。Prunus ×yedoensis Matsum。所占比例最高(52.1%)，次之为小木参。短毛变种Nakai和P. jamasakura Siebold ex Koidz。P. ×nudiflora (Koehne) Koidz。在此次调查中没有发现原产于济州岛的龙葵。为了更好地从微观形态上识别樱桃树，本文提出了11个主要园林绿化树种的识别键。众所周知，在自然界中，樱桃树经常形成种间杂交。为了防止外来樱花树杂交和基因渗入导致本土种遗传原创性的丧失，有必要对本土分类群栖息地附近的种植物种进行管理，并对其起源进行追踪。

This review provides information about the nomenclatural status of new names proposed by Dr. Yong No Lee, in accordance with the current International Code of Nomenclature for Algae, Fungi, and Plants. A total of 363 designations and names were proposed from 16 books and 95 papers by Dr. Yong No Lee, and their status was examined, with 161 designations found to be not validly published. In addition, 13 later isonyms and ten later homonyms were found by this review. However, 173 names were found to be legitimate. All designations and names were categorized according to their nomenclatural status and were listed by place of publication. The nomenclatural statuses of six designations or names, including “Iris odaesanensis,” were not confirmed in this review. It is therefore necessary to undertake further research into the nomenclatural status of these taxa by examining their types and published protologues.

Halenia coreana is an endangered, endemic species that is distributed in only a few locations in Korea, such as Mts. Hwaaksan and Daeamsan. It has been recently segregated from H. corniculata, broadly distributed in cold temperate regions that include northern Japan, the Russian Far East, northeastern China, Mongolia, and eastern Europe, where population sizes are usually large. To examine the genetic diversity of H. coreana and evaluate the level of genetic differentiation of the species compared with that of H. corniculata, we surveyed 183 candidate simple sequence repeats (SSR) motif markers for H. coreana and H. corniculata from sequence data of amplified fragments of a specific length in the genome. A total of 17 genomic-SSR markers were selected to examine the levels of genetic diversity and differentiation using 17 samples of H. coreana and 60 samples of three populations of H. corniculata. The results here suggest that the genetic diversity of H. coreana is very low with a high frequency of inbreeding within its population. We found that H. coreana is genetically differentiated from H. corniculata, supporting the recognition of the geographically isolated H. coreana as a distinct species.

We report a previously unrecorded woody species, Stachyurus praecox Siebold & Zucc. (Stachyuraceae), in Korea. This species is considered to be endemic to Japan. Stachyurus praecox was collected for the first time in an evergreen forest on an uninhabited island of Bongsun-ri, Saengil-myeon, Wando-gun, Jeollanam-do in Korea. The inflorescence of the species was racemose and pendulous on the axils of the previous year’s branches. Flowers bloomed from March to April. They were functionally dioecy but morphologically hermaphrodite. This woody species was named ‘Wan-do-sul-kkot-na-mu’ in Korean based on the shape of its inflorescence. Morphological characteristics and illustrations of this woody species have been provided with a distribution map and photographs of the natural habitat.

The chloroplast genome of Glycyrrhiza uralensis Fisch was sequenced to investigate intraspecific variations on the chloroplast genome. Its length is 127,689 bp long (34.3% GC ratio) with atypical structure of chloroplast genome, which is congruent to those of Glycyrrhiza genus. It includes 110 genes (76 protein-coding genes, four rRNAs, and 30 tRNAs). Intronic region of ndhA presented the highest nucleotide diversity based on the six G. uralenesis chloroplast genomes. A total of 150 single nucleotide polymorphisms and 10 insertion and deletion (INDEL) regions were identified from the six G. uralensis chloroplast genomes. Phylogenetic trees show that the six chloroplast genomes of G. uralensis formed the two clades, requiring additional studies to understand it.
对甘草叶绿体基因组进行了测序，探讨了其种内变异。全长127,689 bp (GC比34.3%)，叶绿体基因组结构不典型，与甘草属一致。它包括110个基因(76个蛋白质编码基因，4个rrna和30个trna)。ndhA内含子区核苷酸多样性在6个G. uralenesis叶绿体基因组中最高。从6个乌拉尔猕猴桃叶绿体基因组中共鉴定出150个单核苷酸多态性和10个INDEL区。系统发育树显示，乌拉尔杉的6个叶绿体基因组形成了这两个支系，需要进一步的研究来了解它。

Its length is 127,689 bp long (34.3% GC ratio) with atypical structure of chloroplast genome, which is congruent to those of Glycyrrhiza genus. It includes 110 genes (76 protein-coding genes, four rRNAs, and 30 tRNAs). Intronic region of ndhA presented the highest nucleotide diversity based on the six G. uralenesis chloroplast genomes. A total of 150 single nucleotide polymorphisms and 10 insertion and deletion (INDEL) regions were identified from the six G. uralensis chloroplast genomes. Phylogenetic trees show that the six chloroplast genomes of G. uralensis formed the two clades, requiring additional studies to understand it.","PeriodicalId":52232,"journal":{"name":"KOREAN JOURNAL OF PLANT TAXONOMY","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48672903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
