  • New somatic chromosome numbers and karyotype analyses of 33 medicinal herbs (30 genera, 23 families) in Korea were investigated. The chromosome numbers of 4 taxa, Euryale ferox, Rodgersia podophylla, Cirsium japonicum var. ussurience, Eehinops setifer, showed results that are different from previous reports. Among 33 taxa, 23 taxa were reported for the first time, and karyotype analyses were newly conducted for 2 taxa (Tiarella polyphylla, Crepidiastrum denticulatum) in Korea. In addition, we observed for the first time the new chromosome numbers for 4 taxa distributed evenly over the world (Lindera erythrocarpa, Corylopsis glabrescens var. gotoana, Ardisia crenata, Callicarpa japonica var. luxurians).

  • The present study summarizes the taxonomic description and Korean distribution of 16 taxa that are recorded for the first time in Korea. These taxa classified into Chlorophyceae (Astrephomene gubernaculifera, Botryococcus protuberans, Chlorangiella polychlora, Cylindrocapsa geminella, Kirchneriella contorta var. gracillima, Korshikoviella gracilipes, Oocystis naegelii, O. ovalis, Stylosphaeridium stipitatum), Charophyceae (Cosmarium moniliforme, Cosmocladium constrictum, C. perissum), Xanthophyceae (Tetraedriella tumidulum, T. spnigera), Chrysophyceae (Cyclonexis erinus) and Cyanophyceae (Arthrospira platensis). Among these taxa, six genera including Astrephomene, Chlorangiella, Cosmocladium, Cyclonexis, Stylosphaeridium, and Tetraedriella are newly recorded in Korea.

  • The subgenus Tricoma Cobb, 1894 comprises free-living marine nematodes encompassing a total of 83 validated taxa. Within this diversity, twenty-one taxa thrive in the deep sea, while twenty-three are found in coral reefs, flat areas, or green algae. Additionally, eleven taxa inhabit the sublittoral zone at depths exceeding 10 meters, and the remaining taxa are situated on beaches, coasts, or in habitats lacking detailed information. In the course of a survey focused on the East Sea free-living marine nematodes, we identified four new and two previously unrecorded species belonging to the subgenus Tricoma. Specifically, two new species, Tricoma (Tricoma) breviseta sp. nov. and T. (T.) donghaensis sp. nov., were discovered in mud-sandy sediment in deepsea environments below 2000 meters within the Ulleung Basin and Hupo Bank. Two previously unrecorded species [T. (T.) paralucida Decraemer, 1987 and T. (T.) similis Cobb, 1912] and the two newly found species [T. (T.) longicauda sp. nov. and T. (T.) ulleungensis sp. nov.] were obtained from subtidal coarse sand at a depth of 20 meters during a survey of the waters surrounding Ulleungdo Island. The distribution and information on validated taxa within the subgenus Tricoma were systematically collected, reviewed, and cataloged. Detailed morphological features and illustrations of Tricoma species from Korea were provided through the use of differential interference contrast microscopy.

  • $L{\acute{e}}veill{\acute{e}}$가 상당수의 한국산 신분류군을 기재하였음에도 불구하고, 이들 분류군에 대한 종합적인 분류학적 검토가 아직까지 국내에서 수행된 바가 없다. 본 논문에서는 $L{\acute{e}}veill{\acute{e}}$가 Decades plantarum novarum이라는 연속 논문에서 한국에서 채집된 표본을 근거로 신분류군으로 발표한 것들의 실체를 파악하기 위하여, 지금까지의 연구 결과를 비교 검토하였다. 그 결과 $L{\acute{e}}veill{\acute{e}}$의 의해 총 275개의 신분류군이 발표되었음이 확인되었다. 이들 가운데에는 Hydrolirion $H. L{\acute{e}}v.$이라는 신속도 포함되어 있으나, 이는 현재 Blyxa Noronha ex Thouars와 같은 분류군으로 간주되고 있다. 나머지 분류군들은 종 수준에서 231개 분류군, 변종 수준에서 43개 분류군이 포함되는 것으로 확인되었다. 종 수준으로 보고된 분류군 중, 현재까지 종 또는 변종 수준에서 인정되는 분류군은 17개였고, 학자에 따라 종 또는 이명으로 간주되는 분류군은 52개로 파악되었으며, 151개 분류군은 다른 분류군과 동일한 것으로 처리되었다. 한편, 11개 분류군은 국내 학자들에 의해 소개되지 않은 것으로 확인되었다.

  • The concept of natural grouping of plant designated as the "Amentiferous" is no longer given serious credence, and many of the families included in this grouping have been dispersed in diverse order. Because a review of taxonomic treatments of amentiferous taxa reveals diverse classifications, it has become necessary to investigate new characteristics and attempt to determine the significance of these characteristics in terms of amentiferous taxonomy. Protein analyses by isoelectrofocusing(IEF) and rocket immunoelectrophoresis(RIE) have proved to be useful in the delicitation of Quercus taxa using pollen extracts from selected taxa. When Quercus pollen extracts were separated by electrophoresis based on their isoelectric points in a stable pH gradient and substrates for estrase activity were stained, ten bands were revealed between pH 5-14. Within Lepidobalanus grouping, a great diversity in the pollen protein zymograms was observed with some segregation corresponding to the designated taxonomic sections. Two taxa of Cyclobalanopsis produced a zymogram that is somewhat similar to taxa included within the section Prinus of Lepidobalanus, and less similar to taxa within the section Cerris of the same subgenus. Three tested taxa of the Cerris are in the similar zymogram each other, being segregable from the taxa of Prinus. Quantitative and qualitative analyses for serological relationships within and among th Quercus were also employed. To calculate the degree of protein similarity, total rocket heights obtained from RIE provided an index of serological correspondence(SC). It is reconfirmed that the Quercus is distantly separated from the Fagus according to SC. Comparative data from rocket number and SC in the tested taxa of Quercus also indicate that Lepidobalanus is separable from Cyclobalanopsis. Within the Lepidobalanus Q. acutissima and Q. acutissima x variabilis are almost homogeneors and distinguishable from the other tested taxa of same subgenus. Although the number of taxa tested has been limited, the overall serological evidence best reflects the classification proposed by Redher(1940) and Melchior (1964), having the genus Quercus subdivided into three subgunera: Erythrobalanus, Lepidobalanus, and Cyclobalanopsis.alanopsis.

  • A study on silica-scaled chrysophytes(Chrysophyceae and Synurophyceae) from Mt. Sinbul alpine wetland, South Korea was performed from January 2018 to March 2020 using scanning electron microscopy (SEM). We found a total of 19 taxa of silica-scaled chrysophytes; Mallomonas(13); Synura (3); Chromophysomonas (1); Chrysosphaerella (1); and Paraphysomonas(1), of which six taxa, including two new species(Mallomonas dimorphus sp. nov. and Mallomonas alpestris sp. nov.), were reported for the first time in Korea. All the species are illustrated with SEM micrographs and briefly described with regard to their taxonomy. Two new species were described based on the cell shape, size and ultrastructure of the scales and bristles. Mallomonas dimorphus sp. nov. belongs to the Sectio Heterospinae in that its scales have a flat dome, a reticulated secondary layer and needle shaped bristles. However, this species is distinguished from other taxa in the Sectio by two different patterns of shield ornamentation and a dome ornamentation. Mallomonas alpestris sp. nov. belongs to Series Torquatae (Sectio Torquatae) characterized elongated domed collar scales, domeless body scales and rear scales with a short spine. However, it is different from all other taxa in the Sectio Torquatae as well as Series Torquatae by shield ornamentation of the body and rear scales with evenly spaced transverse ribs and papillae.

  • Heterotrophic flagellates occurring in the marine sediments of Inchon and Ganghwa Island are reported. Fifty-six species from 38 genera were encountered in this survey and two new taxa were recorded: Cyranomonas australis sp. nov. and Gweamonas unicus sp. nov. There was little evidence for endemism because all flagellates including the two new taxa described here have been found from other habitats in Australia which are geographically remote from Korea. This study supports the model that free-living heterotrophic flagellates have a world-wide distribution.
