An unrecorded species, Poa tuberifera Faurie ex Hack., was found in Saryeoni forest, Jocheon-eup, Jeju-si, Jeju-do. It can be distinguished from P. acroleuca Steud. and P. acroleuca var. submoniliformis Makino by its morphological characteristics, with panicle branches bearing sparse spikelets and lemmas not wavy-haired at the base. P. tuberifera is known to be an endemic plant of Japan, but its distribution in South Korea is confirmed through the present study.

We report Vallisneria spinulosa S. Z. Yan (Hydrocharitaceae) as an unrecorded species from the flora of Korea. This aquatic vascular plant occurs in reservoirs, streams, and ditches at Changnyeong, Changwon, and Gimhae which belong to Nakdong river basin. Vallisneria spinulosa is distinguishable from V. natans (Lour.) Hara already known to Korean flora by the presence of turion and hairs at base of stamen, adnation between pistil and staminodia, the number of stamen, and shape of fruit and seed. V. spinulosa is similar to V. desnseserrulata Makino in the viewpoint of distribution (Japan and southern China), but V. spinulosa has three to five epidermal wings on the surface of seed.

We report an unrecorded plant species, Elatostema laetevirens Makino (Urticaceae), in Korea. This species was collected for the first time from under the canopy of an evergreen forest in Hyodoncheon, Sanghyo-dong, Soeguipo-si and Tamra valley in Ohdeung-dong, Cheju-si of the Province of Cheju in Korea. E. laetevirens Makino was quite distinct from others of the genus Elatostema in Korea owing to its perennial nature, the absence of trichomes in the stem and the absence of peduncles during the inflorescence period. This species was given the Korean name 'pu-reun-mong-ul-pul' based on the absence of luster and the bluish green color on the adaxial surface of its leaves.

A fungus that can capture nematodes by means of sessile adhesive knobs was isolated from rotten wood in Uiseong, Korea. It was found to produce single, spindle-shaped, 3-4 septate (commonly 4-septate) conidia, $44.8\;{\mu}m$ (range, $41.6-50.1\;{\mu}m$) long and $13.3\;{\mu}m$ (range, $10.7-15.4\;{\mu}m$) wide. Conidiophores were found to be hyaline, erect, straight, and $202.7-245.7\;{\mu}m$ high. On the basis of these morphological features, the fungus was identified as Monacrosporium phymatopagum. This is the first report of M. phymatopagum in Korea which can be a potential biological control resource of plant parasitic nematode.

We report a unrecorded species, Da-do-sae-u-nan-cho (Calanthe ${\times}$ kibanakirishima F. Maek). It was discovered on Heuksan Island in Jeollanam Province. The species differs from C. aristulifera in the corolla color and the short, wide spur. It is also easily distinguished from the other species of Calanthe by the simple trichomes on the abaxial surface of its leaves and spur.

Cynanchum L. in the subfamily Asclepiadoideae (Apocynaceae) includes four recognized species on the Korean peninsula, two of which are native to South Korea. However, the species ranges in South Korea are poorly defined. During a field survey, we discovered C. thesioides, previously unrecorded in South Korea, in Gimpo-si, Gyeonggi-do, and found an additional population of C. chinense, for which only one population has been reported in South Korea. The two taxa are considered rare species with extremely restricted distributions in South Korea, especially C. thesioides. We provide fundamental information, including descriptions, images of the habitats and morphological characters, and a taxonomic key for identification and assessments of the conservation status of Cynanchum species in Korea.

Four unrecorded species (Barbella flagellifera, Isothecium hakkodense, Mnium orientale and Fissidens gardneri) and with one unrecorded genus, Barbella, are reported new to the Korean moss flora. B. flagellifera (Meteoriaceae) was found on a tree at alt. 300-350 m of parasitic Seogeomun-oreum Volcano on Jeju Island. The species are mainly distributed in subtropic regions. I. hakkodense (Lembophyllaceae) was found around the top of Seongin-bong on Ulleung Island. This species is similar to I. subdiversiforme, however, it can be distinguished by the morphologies of branch leaves and alar cells. M. orientale (Mniaceae) was collected from Mt. Jiri. This is similar to M. heterophyllum, however, it can be distinguished by plant size, number of teeth in leaf margin and cell size on leaf. F. gardneri (Fissidentaceae) was found along the valley of Mt. Palyeong, Jeollanam Province. This species is similar to F. obscurirete, but distinguished by the size of the plants and their leaves as well as the costal lengths of the leaves.

Given that the Korean genus Elymus L. (Poaceae) is often confused with Agropyron Gaertn., the categories and characteristics of Elymus s.l. have been reviewed morphologically. Two unrecorded taxa of Elymus, E. humidus (Ohwi & Sakam.) T. Osada and E. shandongensis B. Salomon, not previously recorded in Korean flora to date, we report here as an unrecorded species based on samples collected from Chungcheongbuk-do, Gyeongsangnam-do, Jeollanam-do, and Jeollabuk-do. E. humidus is distinguished from other taxa in terms of its habitat around riversides, erect inflorescences, spikelets appressed to rachides of inflorescence, and new individuals asexually propagated at the lower nodes of aerial stems. E. shandongensis is similar to E. tsukushiensis var. transiens (Hack.) H. Osada but is distinguished by the flowering time, slightly curved inflorescences, number of veins of the glumes, and spikelets appressed to the rachides. Descriptions of the two unrecorded Korean taxa, photographs, and keys to neighboring taxa are presented.

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.
