We provide information on 143 sheets of type specimens of 39 species and infraspecific taxa of vascular plants stored in the herbarium of the National Institute of Biological Resources. The specimens were donated by Changwon National University (Prof. Hyeok-Jae Choi), Chungbuk National University (Prof. Byoung-Un Oh), Ewha Womans University (Prof. Chang-Sook Lee), Hallym University (Prof. Young-Dong Kim), Jeonbuk National University (Prof. Muyeol Kim), Korea National Arboretum, Mokwon University (Prof. Jeong Ki Sim), Sungkyunkwan University (Prof. Seung-Chul Kim), and some researchers at KB. The specimens included four sheets for holotypes, 46 sheets for isotypes, and 93 sheets for paratypes of three species and infraspecific taxa of pteridophytes, 21 dicotyledons, and 15 monocotyledons. Nine sheets were sourced from China and 134 sheets were sourced from Korea.

We determined the complete chloroplast genome sequence of the peatmoss Sphagnum subsecundum Nees from Mt. Halla in Korea. The total size of the chloroplast genome was 140,136 bp, and it consisted of a large single-copy region (LSC) of 98,064 bp, a small single-copy region (SSC) of 21,388 bp, and two copies of inverted repeat (IRa and IRb) regions of 10,342 bp each. The genome encoded a set of 130 genes, comprising 85 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. This species formed a monophyletic clade with S. orientale and S. lenese as the result of ML phylogenetic analysis based on whole gemone sequence of 15 species including one outgroup species.
