  • Carex brevispicula (Cyperaceae) is endemic to Korea and is characterized by constricted achenes, short lateral spikes, and awned staminate and pistillate scales. The species classified in sect. Mitratae occurs throughout South Korea, perennating on mountains and/or rocky slopes under half shadow conditions. Meiotic chromosomes of the species were examined in this study, in which 33 meiotic cells from seven populations were found to be less than 2 ㎛ long with non-constricted chromosomes (n = 34II). The stable chromosome number may be related to the narrow geographical distribution and/or distinct achene morphology. Further investigations of the distribution, morphological character variation, and chromosome characteristics should be conducted with closely related taxa to understand the derivation of the species and its endemism in Korea.

  • A new unrecorded species, Hypodematium squamuloso-pilosum Ching (Hypodematiaceae), previously known only in China, was newly found on the rocks of a limestone mountain in Yeongwol-gun, Gangwondo, Korea. This taxon is distinguished from H. glanduloso-pilosum (Tagawa) Ohwi, reported as a species of Hypodematium in Korea based on linear lanceolate scales on the rhizome and a stipe base, white long hairs throughout the leaves, rarely reddish brown curly linear scales on the stipe, and oblong-lanceolate basal pinna. This taxon was most similar to H. hirsutum based on the plant height, rhizome, scale shape and size, sori position, and indusium shape. A new Korean name, 'Huin-geum-teol-go-sa-ri', was given based on the long white hair throughout. Descriptions and illustrations of this taxon and a photograph of its habitat are provided from Korea.

  • 일본 남부와 대만에 분포하는 것으로 알려진 난과의 애기방울난초 (Habenaria iyoensis)가 제주도 서귀포시 저지대에서 발견되었다. 이 종은 3 맥을 가진 꽃받침, 짧은 원통형의 거, 로젯형의 근생 잎에 의해 다른 해오라비난초속 식물들과 구별된다. 국명은 방울난초 보다 작으므로 애기방울난초로 신청하였다. 애기방울난초의 형태적 특징을 기재하고, 도해와 생태 사진을 첨부하였다.

  • One key step in the plant restoration process is the collection of seeds from the field. For the selection of source populations of target plant species for translocation purposes (reintroduction or reinforcements), several approaches are possible. A practical method involves the use of data from reciprocal transplant studies. If no direct data are available, knowledge of population genetics and the phylogeography of the target species can serve as an alternative. In this short review, we briefly propose guidelines for those collecting seeds for plant species restoration based on population genetics theory, focusing on two main questions: Where does the plant material come from and how are sources designated, and how are seeds efficiently collected from local populations? While genetic data on a larger scale (phylogeography and population genetics) are needed to form a reply to the first question, similar data on a smaller scale (fine-scale genetic structures within populations) are necessary to shed light on the second issue.

  • The Illam district, situated in the extreme North Eastern part (Latitude 26.58N and 87.58E Longitude) of Nepal, is a hot spot for floral diversity. The study of wild edible plants of this region was an attempt to highlight the types of wild flowering plants found there and mode of use by the people of the Illam hills. In this respect, a survey of natural resources of some of the representative regions of the district was undertaken and more than 74 major varieties of plant species were found to be used frequently by the people of the hills. The rich diversity occurring in Dioscoriaceae, Moraceae, Rosaceae, Myrtaceae, Poaceae, Urticaceae and Arecaceae provided the wild angiospermic species commonly used by the people of the hills.

  • The chromosome number of myoga ginger (Zingiber mioga (Thunb.) Roscoe: Zingiberaceae) has been reported as 2n = 22 for Chinese plants and 2n = 55 for Japanese plants. We checked the chromosome number of Z. mioga in plants collected in Jeollabuk-do and Jeollanam-do, Korea, and counted 2n = 44, the first report of this number for the species. As the basic chromosome number of Z. mioga is thought to be x = 11, Z. mioga plants in China, Korea, and Japan appear to be diploids, tetraploids, and pentaploids, respectively. In finding the tetraploid race of Z. mioga in Korea, we can hypothesize that the pentaploid race in Japan is derived through the fertilization of reduced gametes of the diploid race and unreduced gametes of the tetraploid race.

  • Hibiscus sabdariffa L., (roselle) in the Malvaceae family is an erect subshrub known to be native to India and Malaysia. It is widely used as a food or tea material around the world, and its therapeutic effects have been widely studied. In this study, the sequencing of the complete chloroplast genome of H. sabdariffa was carried out. The result indicates a genome size of 162,428 bp, which is composed of a large single copy of 90,327 bp, two inverted repeats of 26,242 bp each, and a small single copy of 19,617 bp. Overall, a total of 131 genes were predicted, including 86 coding sequences, 37 tRNAs, and 8 rRNAs. According to a phylogenic analysis, it was clearly distinguished from outgroups such as other species of the genus Hibiscus used in the analysis.

  • The genus Gueldenstaedtia Fisch. is small genus of Fabaceae that includes four species worldwide. Among these, G. monophylla Fisch and G. verna (Georgi) Boriss. are currently recognized as occurring in Mongolia. Here, we present our findings on G. verna from our recent field surveys in eastern Mongolia in 2020. Gueldenstaedtia monophylla is mostly distributed in the western region, whereas G. verna occurs in eastern Mongolia. The regional conservation status of both species was assessed as near threatened based on criterion B in the country. We provided descriptions, grid distribution maps, taxonomic notes and photographic illustrations of the two species based on our newly collected samples.

  • Aruncus aethusifolius (H. Lév.) Nakai is an endemic species in Korea and is economically important as an ornamental herb. The complete chloroplast genome of A. aethusifolius is 157,217 bp long with four subregions consisting of 85,207 bp of large singlecopy and 19,222 bp of small single-copy regions separated by 26,394 bp of inverted repeat regions. The genome includes 131 genes (86 protein-coding genes, eight rRNAs, and 37 tRNAs). Phylogenetic analyses demonstrates that the chloroplast genome of A. aethusifolius was sister to A. dioicus var. kamtschaticus, forming the strongly supported clade of Aruncus. This is the first report of the chloroplast genome of A. aethusifolius.

  • We report 14 species of flowering plants as new additions to the flora of Laos. These are Illex viridis (Aquifoliaceae), Capparis erycibe (Capparaceae), Euphorbia bokorensis (Euphorbiaceae), Exacum darae (Gentianaceae), Aeschynanthus cambodiensis (Gesneriaceae), Tetraphyllum roseum (Gesneriaceae), Utricularia gibba (Lentibulariaceae), Macrosolen brandisianus (Loranthaceae), Decaschistia siamensis (Malvaceae), Nyssa yunnanensis (Nyssaceae), Adenia penangiana var. penangiana (Passifloraceae), Pentaphylax euryoides (Pentaphylacaceae), Wikstroemia bokorensis (Thymelaeaceae), and Debregeasia wallichiana (Urticaceae).
