Ipomoea cristulata Hallier f. (Convolvulaceae), native to the desert regions of the central USA to Mexico, was newly found in Gojeong-ri, Deokgwa-myeon, Namwon-si, Jeollabuk-do. This species can be distinguished from I. coccinea by leaves with 3-5 lobes, hirsute distributed adaxially, and corolla entirely red or orange-red. Its Korean name is ‘Na-bi-ip-yu-hong-cho’ based on its butterfly-shaped leaves. We provide a detailed description, photographs, habitat details, and a taxonomic key to related taxa.

Sustainable habitats play a significant role in determining the survival and habitat preservation of endangered species. To conserve the endangered species Iris dichotoma Pall. and its habitat in Taeanhaean National Park, we collected seeds from a natural population and germinated and propagated them in a greenhouse. In 2019, the propagated individuals of I. dichotoma were transplanted at two study sites in Taeanhaean National Park. After conservation translocation, annual monitoring was conducted from 2020 to 2022, and factors related to the survival and growth of I. dichotoma (clonal propagation rate [%], the flowering rate [%], the population density [individual/m2], the maximum leaf bundle length [height; cm], the maximum leaf bundle width [cm], and the pedicel length [cm]) were measured. According to the results of the monitoring of the flowering and fruiting periods for three years after transplantation, 82.4% of individuals in total were found to have survived. During 2020 to 2022, the mean population density (individual/m2) increased from 0.36 to 0.42 and the size of the leaf bundle length and the width both decreased compared to the corresponding figures in 2019 (p < 0.05). According to the findings here, the transplanted population of I. dichotoma is considered to have adapted successfully to its new site in Taeanhaean National Park.

Spiraea prunifolia f. simpliciflora Nakai is a perennial shrub widely used for horticultural and medicinal purposes. We simultaneously obtained the complete plastid genome (plastome) and nuclear ribosomal gene transcription units, 45S nuclear ribosomal DNA (nrDNA) and 5S nrDNA of S. prunifolia f. simpliciflora, using Illumina short-read data. The plastome is 155,984 bp in length with a canonical quadripartite structure consisting of 84,417 bp of a large single-copy region, 18,887 bp of a short single-copy region, and 26,340 bp of two inverted repeat regions. Overall, a total of 113 genes (79 protein-coding genes, 30 tRNAs, and four rRNAs) were annotated in the plastome. The 45S nrDNA transcription unit is 5,848 bp in length: 1,809 bp, 161 bp, and 3,397 bp for 18S, 5.8S, and 26S, respectively, and 261 bp and 220 bp for internal transcribed spacer (ITS) 1 and ITS 2 regions, respectively. The 5S nrDNA unit is 512 bp, including 121 bp of 5S rRNA and 391 bp of intergenic spacer regions. Phylogenetic analyses showed that the genus Spiraea was monophyletic and sister to the clade of Sibiraea angustata, Petrophytum caespitosum and Kelseya uniflora. Within the genus Spiraea, the sections Calospira and Spiraea were monophyletic, but the sect. Glomerati was nested within the sect. Chamaedryon. In the sect. Glomerati, S. prunifolia f. simpliciflora formed a subclade with S. media, and the subclade was sister to S. thunbergii and S. mongolica. The close relationship between S. prunifolia f. simpliciflora and S. media was also supported by the nrDNA phylogeny, indicating that the plastome and nrDNA sequences assembled in this study belong to the genus Spiraea. The newly reported complete plastome and nrDNA transcription unit sequences of S. prunifolia f. simpliciflora provide useful information for further phylogenetic and evolutionary studies of the genus Spiraea, as well as the family Rosaceae.

Naturalized populations of two alien plants were newly found, and we describe their morphological characteristics and habitats with photographs. One is a member of Juncaceae, Juncus torreyi Coville, and was newly found at a pool of a beach in Gangwon-do. This rush is native to North America and belongs to the sect. Ozophyllum (subgen. Juncus) according to certain morphological characteristics, such as its racemose inflorescence, the absence of floral bracteole, and unitubular leaves with perfect septa. J. torreyi is easily distinguishable from Korean rushes by its long rhizomes with swollen nodes and globular head with 25–100 flowers. Its introduction into Japan and Europe was reported, but the ecological risk associated with its over-dispersal is not known. The other alien plant is a submerged plant, Egeria densa Planch. (Hydrocharitaceae), which was found in streams in Gyeongsangbuk-do and ditches in the Busan-si area, both of which being in the watershed of the Nakdong River. Egeria densa is similar to Hydrilla verticillata (L.f.) Royle, which is native to Korea. However, it is distinguished from H. verticillata by its larger flowers and lack of overwintering organs. This alien plant is native to South America and was introduced for aquarium gardening and naturalized around the world. Egeria densa is treated as a malignant weed due to its asexual reproduction and rapid growth. Size changes and the number of populations of E. densa must be investigated.

We have determined the complete chloroplast genome of Erigeron canadensis isolated in Korea. The circular chloroplast genome of E. canadensis is 152,767 bp long and has four subregions: 84,317 bp of large single-copy and 18,446 bp of small single-copy regions are separated by 25,004 bp of inverted repeat regions including 133 genes (88 protein-coding genes, eight rRNAs, and 37 tRNAs). The chloroplast genome isolated in Korea differs from the Chinese isolate by 103 single-nucleotide polymorphisms (SNPs) and 47 insertions and deletion (INDEL) regions, suggesting different invasion sources of E. canadensis in Korea and China. A nucleotide diversity analysis revealed that the trend of the nucleotide diversity of E. canadensis followed that of 11 Erigeron chloroplasts, except for three peaks. The phylogenetic tree showed that our E. canadensis chloroplast is clustered with E. canadensis reported from China. Erigeron canadensis can be a good target when attempting to understand genetic diversity of invasive species.

An effective pollinator was investigated based on visiting insects to confirm the pollination mechanism of Impatiens furcillata Hemsl. (cheo-jin-mul-bong-seon), an annual herb that is also a species endemic to Korea that has hardly been studied in relation to pollination ecology. The insects that visited the group of I. furcillata studied here consisted of four orders, 11 families, and 16 species; Hymenoptera had seven species (43.8%), Lepidoptera had four (25.0%), Diptera four (25.0%), and Hemiptera one (6.2%). Visiting insects were divided into those that took only nectar, those that took nectar and pollen, and those that took neither. Insects that are effective for pollination are judged considering the length and body type of their mouth parts, and Amegilla florea Smith (huin-jul-beol) is judged to be the most effective pollinator in the survey area. As a result of observing pollination behavior, when visiting a flower, A. florea, which extended its glossa, approached the front, landed on a wing petal of I. furcillata, crawled into the flower tube, and then backed up and reversed its steps, with pollen adhered to its back. The findings here present basic information about species biology related to both I. furcillata and A. florea.
为确定凤仙花(Impatiens furcillata Hemsl)的传粉机理，研究了一种基于访虫的有效传粉媒介。(cheo-jin-mul-bong-seon)是韩国特有的一年生草本植物，在授粉生态学方面几乎没有研究过。本文研究的毛囊蝗群的昆虫包括4目11科16种;膜翅目7种(43.8%)，鳞翅目4种(25.0%)，双翅目4种(25.0%)，半翅目1种(6.2%)。来访的昆虫分为只采花蜜的，采花蜜和花粉的，以及不采花蜜的。对有效传粉昆虫的判断依据是其口部的长度和体型，调查区域内最有效的传粉昆虫是Amegilla florea Smith (huin-jul-beol)。通过对传粉行为的观察发现，在访花过程中，a . florea伸出舌向前方靠近，落在I. furcillata的翅瓣上，爬进花筒，然后倒过来，花粉粘在背上。本文的研究结果提供了有关毛囊蚜和花蚜的物种生物学的基本信息。

We report a new distribution of Carex foraminata C. B. Clarke on the Korean Peninsula. This species was first reported in China and is distributed in Jiangxi and Zhejiang Provinces. We found this species on Hongdo Island in Heuksan-myeon, Shinan-gun, Jeollanam- do in Korea. Carex foraminata is similar to the related taxa C. brevispicula G. H. Nam & G. Y. Chung, C. chungii Z. P. Wang, and C. genkaiensis Ohwi in that its achenes are constricted in the middle part. However, C. foraminata is distinguished from C. brevispicula and C. chungii by its pistillate scale apexes, which are acute or shortly awned and by its achene apexes, which are shortly cylindrical; C. foraminata is distinguished from C. genkaiensis by its pistillate scale and achene shape. A precise description, illustration, photographs, and a key to related taxa are provided.

Bhutan is endowed with rich biodiversity with several edible and useful fern species. Ferns have been used by local communities for centuries as vegetables, ethnobotanical artifacts, and as medicines. Owing to the limited study of edible and useful pteridophytes in the country, the knowledgebase remains poor. In this study, we attempt to document edible and useful fern species in the country scientifically while also providing an annotated checklist.

The study aims are to examine the characteristics of artificial and natural hybrids between Viola albida var. albida (= albida, from below) and V. albida var. chaerophylloides (= chaerophylloides, from below), and to confirm if hybrids could be fertile and make populations in their native habitats. The 1st filial (= F1, from below) leaf shape produced by artificial crossing between albida and chaerophylloides was the same as that of V. albida var. takahashii (= takahashii, from below), and F1 bore also both chasmogamous and cleistogamous flowers. F1 seed number was 9.6 per cleistogamous pods, which was remarkably less than the average of 38.2 for albida and chaerophylloides, but the germination rate was all similar. The leaf type of self-crossed 2nd offsprings (= F2, from below) showed all leaf types found in the Viola albida complex, but the ratio of chaerophylloides leaf type was relatively low. Individuals whose F2 leaf type was restored to albida produced an average of 31.4 seeds per capsule, meaning that fertility was restored. On the other hand, individuals of F2takahashii leaf type come to fruition a low average of 10.4 seeds per capsule, which is similar to that of takahashii. The results of crossbreeding experiment, where is their native habitats, were similar to that of laboratory. Both albida and chaerophylloids in Mt. Bulmyeong distribute extensively, but takahashii make a small population only in places where albida and chaerophylloides grow together. Summarizing the above results is suggesting that the speciation of takahashii was done by hybrid between albida and chaerophylloides, and these have been maintained with relatively small population by cleistogamous capsules.
