The Vietnamese occurrence of Stephania subpeltata H. S. Lo (Menispermaceae) is reported here for the first time. It is morphologically allied to S. japonica but differs in having subpeltate, ovate deltoid or broadly deltoid to subdeltoid leaves, shorter petiole, fewer leaf veins, conspicuously pedicellate umbelliform cymes which are seldom compound, and purple flowers and endocarp with a reduced number of abaxial rows. A taxonomic description, distribution details, ecology, and a key to the Vietnamese species of Stephania are provided.

Sticta (Schreber.) Ach. is one of the common lichen genera in tropical and subtropical regions, but not in the Korean Peninsula. For almost two decades, no detailed taxonomic or revisionary study has been done on this genus. This study was based on the specimens deposited in the lichen herbarium at the Korean Lichen Research Institute, and the samples were identified on the basis of recent literature. In this revisionary study, a total of eight species of Sticta, including a newly recorded one are documented. These species include Sticta fuliginosa (Dicks.) Ach., Sticta gracilis (M$\ddot{u}$ll. Arg.) Zahlbr., Sticta limbata (Sm.) Ach., Sticta nylanderiana Zahlbr., Sticta sublimbata (J. Steiner) Swinscow & Krog, Sticta weigelii (Ach.) Vain., Sticta wrightii Tuck., and Sticta yatabeana M$\ddot{u}$ll. Arg. Detailed descriptions of S. nylanderiana, S. sublimbata, S. weigelii, and S. yatabeana with their morphological, anatomical, and chemical characteristics are provided. A key description of all known Sticta species of the Korean Peninsula is also presented.

The genus Ochrolechia is a widespread, lichen genus in Korea. Despite being common, little is known about the species diversity and geographical distribution of Ochrolechia. In this study, we detailed the identification procedure of the genus Ochrolechia in a Korean collection and provided the description of each species. Using 104 specimens collected from 2003 to 2017, we identified four species of the genus Ochrolechia via morphological and/or molecular phylogenetic analysis: O. parellula, O. trochophora, O. yasudae and O. akagiensis. Among them, O. akagiensis had not been previously reported in Korea. Moreover, the species identified as O. frigida and O. tartarea in past studies were corrected as O. yasudae and O. parellula, respectively, based on morphological and/or molecular evidence. Phylogenetic analysis using the internal transcribed spacer regions including 5.8S rRNA gene showed that the four species separated clearly, indicating that the morphological identification corresponds to the phylogenetic identification. We provide a taxonomic key for the four species of the genus Ochrolechia.

Sparganium coreanum, a barely recognized species in Korea, was rediscovered during a field survey by the authors, who conducted a re-examination of specimens deposited in the Herbarium of the Korea National Arboretum (KH). This species was described initially by H. $L{\acute{e}}veill{\acute{e}}$ from a specimen collected by F. Taquet from Jeju-do (Taquet 2150). Subsequently, however, it was overlooked and unrecognized among South Korean flora. Several populations of S. coreanum were found in the southern part of the Korean Peninsula and on Jeju-do, although it has long been recognized as S. erectum owing to certain vegetative morphological characteristics shared between the two species, such as robust stems, a similar plant height, and globose rhizomes. However, it is distinct from S. erectum by the number of female heads on the lowest inflorescence branch and the size and shape of the fruit. In this study, we provide a detailed description, illustrations, and photographs with a revised taxonomic key for identification of Sparganium species in Korea.

An alien plant of unrecoreded Kickxia (Plantaginaceae) was found in Korea. K. eltine (L.) Dumort. was distirbuted in Yangju-si, Gyoenggi-do and Yeongcheon-si, Gyeongsangbuk-do. This species can be distinguished from the other related genera by having stems that trail along the groud without putting down roots, and the leaves are sagittate, or shaped like arrowheads with longer, narrower, pointed lobes opposite the shorter tip. The new Korean names is given, as 'Hae-ran-cho-a-jae-bi' to Kickxia elatine (L.) Dumort. Here, we provide precise description, illustrations, photographs and taxonomic key to related genera and species.

Symplocarpus koreanus (Araceae; Orontioideae) from Korea is described as new. Symplocarpus koreanus has long been considered to be conspecific with S. renifolius in Japan, but phylogenetic, morphological, and cytological data indicate its taxonomic distinction. Compared to S. renifolius, S. koreanus has a much smaller spathe and more spherical spadix with fewer, smaller flowers. Previous phylogenetic studies also suggested that S. koreanus is more closely related to nonthermogenic S. nipponicus than to S. renifolius in Japan. Like its nonthermogenic sister species, S. nipponicus, in Korea and Japan, S. koreanus is diploid (2n = 2x = 30), while S. renifolius in Japan is tetraploid (2n = 4x = 60). A detailed species description, geographical distribution, major morphological differences between the species and a dichotomous key to the species in eastern Asia are provided.

Korean Sedum formosanum N. E. Br. (Ju-geog-nip-gaet-bi-reum in Korean) was first recorded in 1887, 133 years ago. Since then, the species has not been collected and its current state has remained unclear. However, these plants were collected in 2020 and the corresponding taxonomic entity and distribution status were revealed. It is known to be distributed only in the southern region of Japan, the northern islands of the Philippines, and in Taiwan, with Taiwan being the collection site of the type specimen. However, on the basis of the findings of the fourth national natural environment survey, it has recently been established that this plant also grows in the crevices of rocks along the seashores of the Korean islands of Hataedo Island and Sangtaedo Island, Sinan-gun, Jeollanam-do. S. formosanum inhabiting Korea is a large succulent biennial that can attain a height of up to 65 cm and differs from its congeneric species in having erect follicles during the fruiting period. Notably, among the Korean Sedum species, S. formosanum is most similar to S. tosaense, although it can be distinguished from this species with respect to its monomorphic leaves that have rounded apices, and it also bears separate flowering and sterile stems. In this paper, we present a description and photographs of the Korean S. formosanum, indicate the differences between this and related species, and provide a key to related taxa.

Taxonomic characteristics of spores of 17 species belonging to 6 genera of the Korean Thelypteridaceae are examined. Description of each species and key to the species are provided. Spores of Korean Thelypteridaceae are monad and monolete with bilateral symmetry. Perispore, the sporoderm of spore, was found in all the species examined. The perispores and exospores of Thelypteris japonica var. japonica, T. japonica var. glabrata and Pseudocyclosorus subochthodes are much similar to each other, but the rest of taxa examined shows diverse patterns of the surface ornamentation of perispores and exopores enough to distinguish genera and sometimes to distinguish species in some genera. Previous study reported that perispore is not easily distinguished from exospore in Cyclosorus and Leptogramma. However, three species of Cyclosorus examined here show different pattern having scabrate or verrucate exospores and cristate or echinate perispores. Leptogramma pozoi ssp. mollisima also have echinate perispore and fossulate exospore. Macrothelypteris oligophlebia var. elegans and M. viridifrons have scabrate exospore which is contrast to previous report of reticulate exospore. Thelypteris glanduligera, T. angustifrons and T. laxa show same patterns of perispore and exospore with reticulate perispore and fossulate exospore and hence cannot be distinguished by spores only.
