  • A new species of Hedysarum (Fabaceae, Hedysareae) was found in Tibet, China. This new species, Hedysarum hirtifoliolum, belongs to sect. Hedysarum and is readily distinguishable in having greenish yellow flowers, pubescent above surface of leaflets and transversely obovate loments. So far, it is collected from only one locality in Tibet.

  • The pollen morphology of 31 taxa, representing all woody species from 12 genera of Fabaceae in Korea, was examined by light microscope and scanning electron microscope. The pollen grains were monad and prolate spheroidal or rarely subprolate in equatorial view. The pollen grain aperture was trizonocolporate or rarely trizonooperculate, which does not occur in the other families of Fabales in Korea. The exine showed a great variety of sculpture pattern, i.e. psilate, microperforate, densely microperforate, perforate, polygonal perforate, macroperforate, macroperforate with granules in holes, polygonal macroperforate, verrucate with pitted perforate striae, verrucate-perforate, granulate, rugulate, reticulate or refined reticulate. The pollen morphological data supported the idea that the genera Echinosophora and Sophora were congeneric. Caragana (Galegeae) was quite close to the Sophora group (Maackia, Sophora and Echinosophora) of the Sophoreae in each measured pollen parameter and exine sculpture pattern. Eleven genera of Fabaceae were recognized based on differences in aperture type, pollen grain shape and exine pattern, and a generic pollen key of the woody Fabaceae in Korea was developed. A key to pollen types of Lespedeza was also suggested. The examined taxa of Coronilla and Wisteria were recognized by their exine patterns.

  • The Fabaceae family are being used as traditional medicine. The aim of this study was to compare the antioxidant effects as well as the cell protecting effects of extracts of 5 species (Astragalus membranaceus, Caesalpinia sappan L., Glycyrrhiza uralensis F., Pueraria lobate O., Pterocarpus santalinus L.) in Fabaceae family. The extracts from 5 species were tested by radical scavenging activity test, total phenolic contents and the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay on human liver carcinoma (HepG2) cell line. Anti-oxidant effects of the extracts (5 mg/mL) from C. sappan was 93.49% by radical scavenging activity test. In addition, A. membranaceus extracts showed a weak radical scavenging activity. Anti-oxidant effects of the extracts (5 mg/mL) from A. membranaceus was 7.83% by radical scavenging activity test. Total phenolic contents of the extracts from C. sappan and A. membranaceus were 310.93 mg GAE/g extract, 15.33 mg GAE/g extract, respectively. Cell protecting effects against H2O2 treatment were observed at 100 ㎍/mL concentration of C. sappan and P. santalinus extracts. These results suggest that C. sappan and P. santalinus might be best anti-oxidant in Fabaceae family.

  • Trifolium resupinatum L. (Fabaceae) is native in Southern Europe and Southwesten Asia. This species is known as a naturalized plant, which is widely distributed in the world. We first found it in the Eushincheon river bank of Jindo Isl., Jeollanam-do, South Korea. T. resupinatum can be easily distinguished from the other species of the same genus by its resupinate flower. The Korean name "Geo-kkul-kkot-to-kki-pul" indicates its distinctive characteristic of flower.

  • The chloroplast genome of Glycyrrhiza uralensis Fisch was sequenced to investigate intraspecific variations on the chloroplast genome. Its length is 127,689 bp long (34.3% GC ratio) with atypical structure of chloroplast genome, which is congruent to those of Glycyrrhiza genus. It includes 110 genes (76 protein-coding genes, four rRNAs, and 30 tRNAs). Intronic region of ndhA presented the highest nucleotide diversity based on the six G. uralenesis chloroplast genomes. A total of 150 single nucleotide polymorphisms and 10 insertion and deletion (INDEL) regions were identified from the six G. uralensis chloroplast genomes. Phylogenetic trees show that the six chloroplast genomes of G. uralensis formed the two clades, requiring additional studies to understand it.

  • Vicia bifolia Nakai (Fabaceae) and Cyperus compressus L. (Cyperaceae) have been ambiguous in terms of their distribution and taxonomic entities in Korea. The existence of these two taxa was confirmed when V. bifolia and C. compressus was found on Jellabuk-do, Gyeongsangnam-do, and Jeju-do. Vicia bifolia is similar to V. unijuga by having a pair of leaflets but is distinguished by the length of the petiole, the size and degree of longevity of the bracts, and the shape of the stipules. Cyperus compressus was found on Jeju-do, is similar to C. tenuispica, C. haspan, and C. flaccidus, but is distinguished by the branching pattern of the inflorescences and the size of scales and achenes. A description, differences from related species, a key to the taxa and photographs of Korean Vicia bifolia and Cyperus compressus are provided in this study.

  • Melilotus dentatus (Waldst. & Kit.) Desf. is an invasive plant native to Europe, Russia, Uzbekistan, Mongolia and China. It was introduced to North America to create grazing areas for livestock; its growth has since become uncontrollable. Melilotus dentatus is now found in Namyang-eup, Hwaseong-si, Gyeonggi-do, South Korea as an alien plant. This species is morphologically similar to Melilotus suaveolens Ledeb. and Melilotus officinalis (L.) Lam. M. dentatus differs from other species based on its oblong leaflets, distinct teeth, two ovules, surface of the legume that is minutely reticulate-nerved or smooth, and seeds that are dark green to greenish brown. Here, we have provided a detailed description and photographs of the alien species M. dentatus as well as an updated key to five Melilotus taxa studied, which will help prepare a continuous monitoring and management plan.

  • The genus Gueldenstaedtia Fisch. is small genus of Fabaceae that includes four species worldwide. Among these, G. monophylla Fisch and G. verna (Georgi) Boriss. are currently recognized as occurring in Mongolia. Here, we present our findings on G. verna from our recent field surveys in eastern Mongolia in 2020. Gueldenstaedtia monophylla is mostly distributed in the western region, whereas G. verna occurs in eastern Mongolia. The regional conservation status of both species was assessed as near threatened based on criterion B in the country. We provided descriptions, grid distribution maps, taxonomic notes and photographic illustrations of the two species based on our newly collected samples.

  • Desmodium paniculatum (Fabaceae), native to North America and an alien plant in Japan, was newly found in Hwaseong-si and Daejeon-si, Korea. This species is distinguished from Korean-related taxa based on certain morphological features. Specifically, it is a perennial herb, with a 4-5 jointed loment, and with the basal suture moderately incised between the articles. In the field, D. paniculatum grows around rivers and roadsides, suggesting that it is likely to have been introduced through river improvement work and road construction. On the phylogenetic tree based on an internal transcribed spacer, Korean individuals forms a clade with a Japanese individual. Here, we report a morphological description, photographs, an illustration, and the locality of D. paniculatum.

  • Hylodesmum laxum (Candolle) H. Ohashi & R. R. Mill subsp. laxum was recorded from Korea. The species is widely distributed in S. E. Asia, but in Korea the plant was the first found in the evergreen forest of Seogwipo-si in Jeju-do. Hylodesmum H. Ohashi & R. R. Mill was raised as a separate genus recently based on Desmodium sect. Podocarpium Benth. Except for two species, all Korean species included in the former Desmodium are classified into the genus Hylodesmum. A key to and enumeration of the Korean species of Hylodesmum are provided.
