Two unrecorded Poaceae species, Anthoxanthum glabrum and Saccharum arundinaceum, are herein newly reported from Korea. Anthoxanthum glabrum (Ae-Gi-Hyang-Mo) was found in Ansan-si, Gyeonggi-do, Sangju-si, Gyeongsangbuk-do and Hwasun-gun, Jeollanam-do. It is distinguished from A. nitens by the length of its spikelet, glume and lemma. Saccharum arundinaceum (Keun-Gae-Sa-Tang-Su-Su) was found in Mapo-gu, Gangnam-gu, Seoul, and Hwasun-gun, Jeollanam-do. It is distinguished from S. spontaneum by hair on the lower glume and according to the length of the hair on the callus of its spikelet. In this study, a description and illustrations of the species and photos of the habitat are provided.

This is a report of an unrecorded species of Hedyotis from Korea, Hedyotis chrysotricha (Palib.) Merr., found in Yeongam-gun, Jeollanam-do. The species can be distinguished from other Hedyotis species by trichomes that cover the entire plant, ovate leaves, mauve or white corolla, and the corolla lobe of which the length measures more than twice its width. The species was named after its findspot and is hence called 'Yeongam-pul.' An illustration, description and key to the taxa related to Hedyotis are provided.

Five taxa of the genus Ajuga L. (Lamiaceae) were known previously in Korea which were mainly distributed in lowland and lower montane areas at 50-1000 m elevation. We report an unrecorded taxon of the genus Ajuga in Korea, namely Ajuga nipponensis Makino. This taxon was discovered at Is. Nok, Boryeong-si, in Chungcheongnam Province. A. nipponensis is found to be distributed along roadsides near villages of the island. A. nipponensis was distinguishable from other Ajuga in Korea by following combination of characters: Stems erect or procumbent, arranged in a dense cluster, corolla whitish-pale pink, 10-12 mm long. This taxon was named 'Bun-hong-kkot-jo-gae-na-mul' in Korean based on color of the corolla. The key to the genus Ajuga in Korea is also provided.

Prunella vulgaris var. lilacina Nakai, P. vulgaris var. aleutica Fernald, and P. vulgaris var. albiflora Nakai have been reported as infrageneric taxa of Prunella L. in Korea. I found many samples of P. pinnatifida Pers. in the previously collected herbarium sheets in several major herbaria in Korea and confirmed its distribution again in Jaeun Island, Chonnam Province with the information from those herbarium sheets. P. pinnatifida Pers. has deeply lobed leaves in contrast to entire or barely dentate leaves of P. vulgaris var. lilacina Nakai, P. vulgaris var. aleutica Fernald, and P. vulgaris var. albiflora Nakai. I first report the distribution of this taxon in Korea and give it the Korean name Gal-re-kkul-pul. I provide description, illustrations, and an infrageneric key to identification of the other taxa of Prunella in Korea, and discuss some taxonomic problems of this taxon.

Two newly recorded species, Cyrtomium laetevirens and Dryopteris simasakii var. paleacea (Dryopteridaceae) were collected from forests in Jeonnam, Geongnam and Jeju-do, with the latter also, found addedly in Gwanaksan, Seoul. C. laetevirens (vernacular name: 'Yun-soe-go-bi) was distinguished from other Korean congeners of the genus Cyrtomium by having glossy laminae, narrow lanceolate, yellow-green pinnae with minutely serrated margin and gradually narrowing shape from base to apex, along with entire, unicolor, and white grayish indusia. D. simasakii var. paleacea (vernacular name: Cheung-cheung-ji-ne-go-sa-ri'), was distinguished by shining leaves, opposite pinnae arrangement, no falcate pinnules, and densely adpressed scaly wholly along with irregular dark brown scales on stipe and rachis. Descriptions and illustrations of the two taxa and their photographs in the habitat are provided along with a key to the species of Cyrtomium and sect. Hirpedes of Dryopteris from Korea.

The newly recorded species, Diplazium mettenianum (Miq.) C. Chr. var. mettenianum (Athyriaceae) was collected from a forest in Min-oreum, Jeju-do. D. mettenianum var. mettenianum (vernacular name: 'Kit-ju-reum-go-sa-ri') is distinguished from other Korean congeners of the genus Diplazium by having pinnae shallowly or halfway lobed, lower pinnae stalked, lanceolate, pinna segments serrate margin and obtuse apex. A new Korean name, 'Kit-ju-reum-go-sa-ri', was given based on the shape of pinna halfway lobed. Descriptions and illustrations of this taxon and its photograph in the habitat are provided along with a key to the species of Diplazium from Korea.

Two unrecorded naturalized species, Stachys agraria Schltdl. & Cham. and Dracocephalum moldavica L (Lamiaceae), are newly reported in Korea. Stachys agraria and D. moldavica were found at Seogwipo-si on Jeju-do and at ChunChen-si in Gangwondo in Korea, respectively. Stachys agraria is distinguished from other related Korean taxa by corolla of 2.4-5.2 mm long with six to twelve flowers in the node. Its local name is "Ae-gi-seok-jam-pul" based on shorter than longer corollar. Dracocephalum moldavica was distinguishable from other Dracocephalum in Korea by the following combination of characters, oblong to ovate-triangular ($1.7-2.4cm{\times}0.8-1.2cm$) leaves and rough crenate at the margin. This taxon is referred to as 'Hyang-yong-meo-ri' in Korean based on its fragrance. We provide a description, illustrations, photographs, and a key of related taxa in Korea.

Platanthera brevicalcarata Hayata (Orchidaceae), previously known to be distributed from Taiwan to southern Japan, was found in the Jeju-do, Korea. This species is distinguished from the related taxon Platanthera chlorantha by its small plant size, white sepal with distinct one green vein, and short-cylindrical spur. The local name Young-ju-je-bi-ran is originated from the local name of Mt. Halla. The morphological characters and illustration of the species are provided with line drawing and photograph from the natural habitat.

We report S. caricina (R. Br) Benth. (Cyperaceae) as an unrecorded species from Sinan-gun, Jeollanam Province on the Korean peninsula. This taxon was known to be distributed mainly in southeast Asia, China, Japan, and the northern part of Australia. S. caricina is distinguished from other species of the genus Scleria in Korea by having congested inflorescences, 3-toothed pistillate scales at the apex, and enclosed achenes in 2 scales. The new Korean common name, 'Ae-gi-gae-ol-mi', is given considering the small-size of the plants. A description based on the morphological characters and the illustrations of this species are provided with a taxonomic key to the species of Scleria in Korea.

Two alien plants Holosteum umbellatum L. and Asperugo procumbens L., belonging to Boraginaceae and Caryophyllaceae, respectively, have been first recorded in Hongseong-gun, Chungcheongnam-do and Incheon, South Korea. This initial investigation reports to inform the importance of detection and extermination of these potential weeds in surrounding areas. Furthermore, we report the morphological characteristic features of these two alien plants.
