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 an unrecorded species of Patrinia in Korea, P. monandra C. B. Clarke. This species was found from Neasosa, Buan-gun, Prov. Jeollabuk-do, Sanghwangbong and Bogildo, Wando-gun, Prov. Jeollanam-do in the southwest of Korea. We named 'Gin-dook-gal' as a common name of this species. It is easily distinguishable from Patrlnia villosa (Thunb.) Juss. by the characteristics such as lemon yellow corolla, one (sometimes three) stamen(s) and fruit fused with large bracteole-wing orbiculate.

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.

Three unrecorded fern species from the flora of Korea belonging to family Dryopteridaceae, Ctenitis maximowicziana, Dryopteris lunanensis, and D. dcipiens var. diplazioides, are found along the valley of Mt. Wolgak (alt. 275m) in Gwangju, Korea. C. maximawicziana is well distinguished from the rest of the species in the genus including C. sinii by the color and morphology of scales in basal part of petioles, shape of blades, and the presence of round-reniform shaped indusia. Dryopteris lunanensis is also well distinguished from its close relative, D. atrata, by the number of lateral pinnae, degree of division of first and/or second pinnules in lower pinnae of the blades, and distribution pattern of sori. Dryapteris decipiens var. diplazioides is distinguishable from type variety by degree of division in lower pinnae of the blades. In terms of morphology, var. diplazioides seems to be intermediate between a type variety and D. fuscipes.

Drosera spathulata Labill., belonging to the family Droseraceae, was recently recorded for the first time in a forest wetland in Busan-si, Gijang-gun, Cheolma-myeon. This plant is distributed from eastern Australia throughout South East Asian, Japan, China, Taiwan, and now, Korea. This species, related by taxa to D. rotundifolia, is distinguished by possessing a smaller leaf size (10-20 mm long, 2.5-4.5 mm wide), racemes that are glandular-hairy, and pinkish petals. The newly given Korean name, 'Jom-kkeun-kkeun-yi-ju-geok' reflects the small size as compared to related taxa. A description of the key characteristics, an illustration, and photographs of the habitats of this plant are provided in this report.

Two naturalized species, Glyceria declinata $Br{\acute{e}}b$. and Puccinellia distans (Jacq.) Parl. are herein newly reported from Korea. Glyceria declinata, 'Yu-Reop-Yuk-Jeol-Bo-Ri-Pul', was found along the Seomjin River, Gurye-eup, Gurye-gun, Jeollanam-do, as well as along the Gwangjucheon River, Sa-dong, Dong-gu, Gwangju. It is distinguished from G. acutiflora by spikelets 15-20mm long and obtuse lemma. Puccinellia distans, "Cheo-Jin-Mi-Kku-Ri-Gwang-I", was found in Yeongjong Island, Incheon, Yongyu Island, Incheon and Chojijin, Ganghwa-gun. It is distinguished from P. nipponica by lemmas 1.8-2.5mm long, ligule 1-2mm long and the lower branches of panicle usually reflexed after anthesis.

While more than 1,000 taxa in Staurastrum were found worldwide, in Korea only 119 taxa, of 68 species 42 varieties 9 forms, were reported so far. In this study, 23 taxa (19 species 4 varieties) of Staurastrum were collected from 15 freshwaters in Korea from Feb. through Nov., 2003. Among these taxa, 12 were newly recorded to Korea. Therefore, the total number of Staurastrum in Korea should be 131 taxa, of 77 species 45 varieties 9 forms, adding 12 newly found taxa. Most of the collected species were coincided with the characteristics previously described, but the sizes of 8 taxa including S. affine were smaller than those previously described. The 7 taxa including S. cerastesa have shown a little dissimilarity in the morphology of semicell and the decoration of cell wall.

The vascular flora of Dalmasan and its adjacent regions, located in Haenam-gun, Jellanam-do, is surveyed from Mar. to Oct. 2005. The number of the vascular plant taxa based on voucher specimens is 545 total which belongs to 112 families, 322 genera, 473 species, 3 subspecies, 60 varieties and 9 forms respectively. Among them, 12 taxa of Korean endemics and 4 taxa of rare and endangered plants were investigated in addition to 86 taxa of specially designated plants announced by the Ministry of Environment. A unrecorded taxon, Stellaria neglecta Weihe, is also collected in this area. Furthermore, The habitat of 5 taxa such as Asplenium trichomanes L., Asplenium wilfordii Mett. ex Kuhn, Miscanthus sinensis var. chejuensis Y.N.Lee, Impatiens kojeensisi Y.N.Lee and Digitaria violascens var. intersita Ohwi were newly added to the flora of korea, and 29 taxa of induced and naturalized plants were observed in this area.

Here we report a previously unrecorded species of Korean Allium (Alliaceae) from Geomundo, Yeosu-si, Jeollanam-do. This taxon, A. pseudojaponicum Makino which has been known to distribute only in the southern part of Japan up to date, is easily distinguished from A. thunbergii G. don by lustrous evergreen leaves and lateral scapes as well as chromosome number (2n=32). The common name, 'Gaet-bu-chu', was newly given considering the property of habitat, which is the dry and rocky grasslands facing to the sea in Korea and Japan. In this study, we redescribe morphological characters, and provide illustrations of habit as well as photographs of habitat.
