  • Carex taihokuensis Hayata (Cyperaceae) is reported from Jin-do (Isl.), SW Korea, for the first time. It belongs to sect. Digitatae, and had been known from Taiwan, China, and Japan. C. taihokuensis is characterized by the staminate terminal spike, bracts with sheath, pilose perigynia, and style base not thickened. We propose the new Korean name, 'Jin-do-sa-cho', after its first collecting place. We also provide a key to species in sect. Digitatae in Korea and Japan.

  • A bacterial disease of elephant foot, Hydrosome rivieri Engl., was newly found in Taejon, Korea in August 1986. The affected plants showed symptoms of soft rot on leaf blades and petioles. Bacterial isolates from affected plants found to be pathogenic to elephant foots by antificial inoculation, producing similar symptoms with those produced naturally. The baterium was also pathogenic to carrot, Chinese cabbage, radish, potato and onion, and developed symptom of soft root on them. On the basis of bacteriological characteristics and pathogenicity, tested bacterium was identified as Erwinia carotovora subsp. carotovora and this disease was proposed to name 'Bacterial soft rot of elephant foot'.

  • In 1991, the leaves and roots brown rot disease of scarlet kafir lily were found in Taejon and Seoul. The symptoms were appeared as dark-brown and water soaked on leaves. The discolored area of the leaves become halo. The roots revealed blight gray and water soaked. The pathogenic bacteria were isolated from the diseased leaves of the scarlet kafir lily were identified as Erwinia cypripedii on the bais of bacterial characteristics. E. cypripedii is first described bacteria which cause the disease on scarlet kafir lily in Korea. Therefore, we would like to propose to the name of scarlet kafir lily disease caused by E. cypripedii as“bacterial brown-rot of scarlet kafir lily”hereafter.

  • Bacterial leaf spot by Xanthomonas campestris pv. vesicatoria has been known to cause serious problem in red pepper in Korea. However recent survey showed that most smptoms in the leaves were mixed with two different symptoms one was leaf spot and the other was canker. bacteria isolated from canker were identified as Clavibacter michiganensis subsp. michiganensis on the basis of biochemical and physiological characteristics. The causal bacteria were non-motile rod-shaped and Gram-positive. The lesions on pepper leaves appeared at first as small blisters or pimple-like white spots which enlarged in size at a later stage. The centers of some of the spots became necrotic and brown and were surrounded by a white halo. Pathogenicity tests were performed on pepper cv. Alchan seedling by spraying of bacterial suspension. During 1997 and 1998 total 17% of 527 fields surveyed were infected by C. michiganensis subsp. michiganensis. The canker of red pepper caused by C. michiganensis subsp. michiganensis was first identified in this study in Korea, and new name "gueyangbyung" was tentatively given to the disease.

  • In 1991, the leaf brown spot of ivy-aureus (Scindapsus aureus) was found in Taejon and Seoul, Korea. The symptoms were appeared as dark-brown spots. The lesions were often surrounded by yellowish halos. These spots were enlarged to circular or elliptical in shape and dark-brown to black in color with slightly elevated in margin and sunken in center. The pathogenic bacteria were isolated from the diseased leaf of ivy-aureus were identified as Erwinia chrysanthemi on the basis of bacterial characteristics therefore, we would like to propose to the name of ivy-aureus disease caused by E. chrysanthemi as“bacterial brown rot of ivy-aureus”hereafter.

  • A bacterial disease of pepper (Capsicum annuum L.) that rooted the stem nodes to black was found in pepper plants which cultivated in plastic house at Chungdo, Kyungpook, Korea in March, 1998. Bacterial isolates derived from the diseased peppers were pathogenic to potato, eggplant and Chinese cabbage but, was not pathogenic to chrysanthemum by artificial inoculation. On the basis of bacteriological characteristics and pathogenicity test on host plants, the causal organism of the node soft rot of pepper is identified as Erwinia carotovora subsp. carotovora and the name of disease is proposed as bacterial node soft rot of pepper.

  • Thymus quinquecostatus var. magnus (Nakai) Kitam., an endemic taxon in Ulleung Island, is lectotypified. The lectotype is designated based on careful examination of the original materials (deposited in TI) cited in the protologue of the variety. In addition, taxonomic identity of T. quinquecostatus var. japonicus H. Hara, a problematic name often mistakenly referred to the above taxon, was throughly reexamined.

  • We reported an unrecorded species of the genus Allium (Alliaceae) which is growing along riversides in the central part of Korean peninsula. A. longistylum Baker, has been known to distribute only in China. The new common name, 'Gang-bu-chu', was given considering the habitat characteristics such as growing riversides in Korea. In this study, we described morphological characters, and provided illustrations as well as photographs of the habitat.

  • We report an unrecorded species of Corydalis sect. Corydalis (Fumariaceae), C. caudata (Lam.) Pers., that have been found in the central part of Korea. This species is easily recognized by its bearded calyx, upwardly curved spur, and multi-branched characteristics. We named it 'Soo-yeom-hyeon-ho-saek' as korean common name.

  • These studies were carried out to develop native Calanthe in Korea. Calanthe native to southern islands in korea has beautiful flowers with various color and sweet fragrance, and it has been reported to have very good ornamental value. Concerning the classified 57 lines had surveyed their characteristics during the three years, and confirmed which that had manifestation stably. And then, a line was developed and given a name of horticultural cultivar to ‘Saegdong’. The major characteristics of the selected line, ‘Saegdong’, were as follows. In its color of flower, sepal was reddish orange, petal was yellow and lip was yellow. ‘Saegdong’ had a bended-inner blooming type.
