We conducted taxonomical investigations based on morphological characteristics, fruit morphology, and literature research on the tribe Potentilleae (Rosaceae) in Korea covering seven genera and 24 species. The style position on the ovary and the shape of style were useful characteristics for the classification of subtribal and generic levels in the...

Flora of Mt. Suri surrounded by four cities near Seoul, Korea have been investigated since 1996. To understand its flora in detail, we investigated flora of Mt. Suri using the Biodiversity Observation Database (BODB; http://www.biodiversitydb.org/). With the aid of BODB and 10 para-taxonomists, we collected 1,502 plant instances with GPS (1,418 ins...

In this paper, we conducted the taxonomic study of the tribe Epilobieae Endl. and concluded that a total of nine taxa, including one Chamerion (Raf.) Raf. ex Holub and eight Epilobium L., exist in Korea. Although C. angustifolium subsp. angustifolium has been placed traditionally either in Epilobium or Chamaenerion, it can be clearly distinguished...
Article
Using scanning electron microscope (SEM), we examined the trichomes on leaf and petiole and the epicuticular waxes on leaf surfaces for a total of 27 taxa representing two subtribes, Fragariinae and Potentillinae, of tribe Potentilleae (Rosaceae) in Korea. Four types of trichomes on adaxial and abaxial surface of leaves and petioles were identified...

Pseudostellaria longipedicellata S. Lee, K. Heo & S. C. Kim is newly described from the Taebaek Mountain Range across three eastern provinces (i.e., Gangwon, Chungcheongbuk, and Gyeongsangbuk) of the Korean Peninsula. Pseudostellaria longipedicellata is similar to P. palibiniana (Takeda) Ohwi by having an open flower, glabrous pedicel, and slender...
Article
Tribe Stewartieae (Theaceae) consists of evergreen Hartia and deciduous Stewartia. Pollen morphology was investigated using light and scanning electron microscopy in 6 species of Hartia and 11 species of Stewartia. Hartia has a reticulate or microreticulate pollen sculpture pattern, a psilate or foveolate margo and a round or acuminate colpus tip,...

Pollen morphology of 13 species of the genus Sanguisorba (Rosaceae) was examined by light and scanning electron microscopy. The pollen morphology divided the genus into two main groups: (A) tricolporate with tapered colpus tips, and (B) either tricolporate with opened colpus tip or hexacolporate. The former group was further subdivided into those w...
Article
Symplocarpus L. (Araceae) is a disjunct genus including S. foetidus (L.) Nutt. var. latissimus (Makino) S. Hara, S. nipponicus Makino, and S. nabekuraensis Otsuka & K. Inoue in temperate eastern Asia; S. egorovii N. S. Pavlova & V. A. Nechaev in the Russian far east; and S. foetidus (L.) Nutt. in temperate northeastern North America. For the first...
Article
Pollen grains from 15 species (18 taxa) of the genus Filipendula were examined with light and scanning electron microscopy. It was revealed that the pollen grains are isopolar, tricolporate, with scabrate or scabrate-microechinate surface. The pollen morphology was compared with the conventional classification systems of the genus by different auth...

... Statistical analysis of the locations of all identified SSRs showed that the number of SSRs located in the LSC region, SSC region and IR regions were 44-52, 8-12 and 4-14, respectively. Furthermore, we found that these SSRs were mainly distributed in IGS (38)(39)(40)(41)(42)(43)(44)(45)(46)(47)(48)(49)(50)(51)(52)(53)(54), and some in the CDS region (9-12) and introns (8-12) (Fig. 3C). A/T (no C/G) is the only mononucleotide SSRs type in the six species, and the repeat units of the other five SSRs were also mainly composed of A or T (Fig. 3D). ...
... This is likely to be due to the fact that the chloroplast genome does not contain enough information to attract researchers comparing with whole genome sequences. However, chloroplast genomes are occasionally useful for unravelling corresponding phylogenetic relationships based on the maternal lineage: e.g., Lindera genus [13], Fagopyrum genus [14], Potentilla genus [15][16][17][18][19][20][21], Pseudostellaria genus [22][23][24][25][26], and Dysphania genus [27][28][29][30]. Moreover, several studies that described assembled organelle genomes from NGS raw sequences generated with different purposes have been conducted [31,32]. ...
... Assembled sequences were confirmed by BWA v0.7.17 (Li, 2013) and SAMtools v1.9 (Li et al., 2009). All bioinformatic analyses were conducted in the Genome Information System (http://geis.infoboss.co.kr/) utilized in the previous studies (Kim et al., 2018(Kim et al., , 2019a(Kim et al., , 2019cBum et al., 2020;Park et al., 2021c). ...
... These diagnostic markers include, first of all, morphological and anatomical signs of vegetative organs. There are very little data on the anatomy of the vegetative organs of P. alba [5]. Most of the available information concerns the anatomical structure of the leaves of plants of the genus Potentilla L. [6,7]. ...
... Until now, the following studies related to endangered species have been conducted in Korea: " Distribution and Conservation (Lim et al. 2010;) " , " Habitat Characteristics Analysis (Kim et al. 2013;Choi et al. 2014) " , " Climate Change (Han et al. 2012;Park et al. 2014) " , " Growth and Reproduction Characteristics (So et al. 2008;Lee and Kim 2011) " , and " Restoration and Evaluation (You and Kim 2010;Bae 2012). " A research on its taxonomy has been conducted (Lee et al. 2013), but basic data on its habitat, growth, and reproduction does not exist. The moisture and organic matter in the soil, which are core factors for plant growth, were treated to obtain basic data on ecological characteristics of Epilobium hirsutum L., an endangered species, for the species conservation and restoration and to find adequate soil conditions based on the data. ...
... Indeed, the species is found in Asia, Europe, and North America. It has long been used in traditional Chinese medicine for treatment of chronic diseases (Hu et al. 2019;Ma et al. 2011), and taxonomic research has documented eight species of Pseudostellaria, three of which, P. heterophylla, P. palibiniana, and P. longipedicellata, are common in Korea (Jo et al. 2014;Lee 1989;Lee et al. 2012). ...
... Stewartia s.s. was described by Linnaeus (1753) based on a specimen from ENA, while Hartia was published by Hooker (1905). Taxonomic debates regarding the circumscription of both genera have lasted for decades (Keng, 1962;Spongberg, 1974;Yan, 1981;Ye, 1982;Li, 1996;Chang and Ren, 1998;Ming and Bartholomew, 2007;Heo et al., 2011). Species numbers also remain controversial for the deciduous taxa (usually referred as Stewartia s.s.) and evergreen species (usually referred as Hartia). ...
... Flower and stem-leaf were airdried in the shade at room temperature and analyzed as soon as possible. The plant was authenticated by Prof. S. Terzioglu (1,(3)(4)(5). The voucher specimen was deposited in the Herbarium of Karadeniz Technical University, Faculty of Forestry (KATO: 16001), Turkey. ...
... In the family Rosaceae and tribe Sanguisorbeae pollen morphology was previously studied only in Northern Hemisphere species. Several authors proposed groups of pollen types for the family (Reitsma, 1966(Reitsma, , 1967Gonzalez Romano and Candau, 1989;Lee et al., 2011). In addition, a number of exine sculpturing patterns have been described (Ikuse, 1955;Eide, 1981;Reitsma, 1966Reitsma, , 1967Naruhashi and Toyoshima, 1979;Hebda et al., 1988aHebda et al., , 1988bHebda et al., , 1991Gonzalez Romano and Candau, 1989;Chinnappa, 1990a, 1990b) that were informative for resolving phylogenetic relationships and for delimiting genera and/or species (Hebda et al., 1988a(Hebda et al., , 1988b(Hebda et al., , 1991Hebda and Chinnappa, 1990a, 1990b, 1994Wen and Nowicke, 1999;Cooper et al., 2000;Pérez De Paz, 2004;Chung et al., 2010). ...
... It is noteworthy that thermogenesis occurs during the anthesis in relation to pollination and should be considered as a reproductive floral trait. (Govaerts and Frodin 2002;Nie et al. 2006; Lee et al. 2010). ...
