Pollen Morphology of the Woody Fabaceae in Korea
Song, Un-Sook ;
Korean Journal of Plant Taxonomy, volume 37, issue 2, 2007, Pages 87~108
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.

Using internal transcribed spacer (ITS) sequences and inter-simple sequence repeats (ISSRs) data, genetic diversity of a rare species, Hibiscus hamabo Siebold & Zucc. was examined for 3 populations in Jeju Island, Korea. A total of 14 nucleotide (excluding 3 ambiguous nucleotide) site variation in the ITS was observed from 18 individuals (Population 1, Hadori), which differed up to 13 bp in pair-wise comparison. On the contrary, the ITS sequences of all individuals in Populations 2 and 3 were identical. Genetic diversity estimates including Nei's gene diversity (h) generated by ISSR data were substantially high in Population 1 compared to other two populations. Low genetic variation in Populations 1 and 2 is considered due to genetic drift (bottleneck effect) and limited gene flow in these populations. Considering the differences in genetic diversity, protection of the Population 1(Hadori) is very critical for in situ conservation of Hibiscus hamabo in Korea. If ex situ conservation is required, making the full use of Population 1 will be most efficient.

Genetic variation of Ilex cornuta Lindley et Paxton was examined by sequence analyses of ITS for 65 individuals from Korea and China. The length of ITS 1 ranged from 253 to 259 bp. The 5.8S was 159 bp and ITS2 was observed to be 231 bp. A total of 8 different ITS types (Single Nucleotide Polymorphism haplotypes), which showed the difference of 1- 6 bp, were detected from 65 individuals. The sequence polymorphisms of ITS appeared at 9 different sites. All of four individuals collected at Daejeong-eup in Jeju-do exhibited different types, but all individuals from Naju-si and Muan-gun in Jeollanam-do were identical. The variation of ITS was higher in Jeju-do population than in inland population. Since 1. cornuta contains various types of ITS sequences, ITS analyses will provide important information on genetic diversity and conservation of this species.

Korean Journal of Plant Taxonomy, volume 37, issue 2, 2007, Pages 143~153
In order to estimate the relationships among four taxa (Styrax japonicus, Styrax obassia, sηrax shiraianus and Pterostyrax hispidus) of two genus in the Styracaceae and their regional populations, RAPDs analysis was performed. Fifteen random primers generating 238 RAPD bands were enough to reveal differences in genotype bands. They were clustered into three groups by the UPGMA phenogram. The first group was Styrax japonicus populations, the second group was consisted of Styrax obass따 populations and S. shiraianus populations, and third group was Pterostyrax hispidus population The UPGMA phenogram based on RAPD analyses showed that Styrax obassia and S. shiraianus had the closest relationship among four taxa. Species as well as genera of the Korean Styracaceae were well discriminated by the RAPD analyses.

This study was carried out to elucidate floristic data of Chirisan National Park by performing practical field investigation for 1· year and literatures survey simultaneously in 2004. The data from field study were yielded based on voucher specimens. Total number and components of flora of Chirisan National Park is revealed as 1,825 taxa. Among 1,825 taxa, 708 taxa were identified in this field study, and these were comprised 37 orders, 109 families, 382 genera, 590 species 3 subspecies 95 varities 20 forms. Unconfirmed taxa in field but recorded previous literatures were 1,117 taxa, which consist of 41 orders 130 families 500 genera 901 species 9 subspecies 140 varities 67 forms. In conclusion, there may be provisionally 1,825 (708+1,117) taxa in Chirisan National Park. The 43 taxa were firstly found out in this field study. In the floristic data from field study, the number of Korean endemic plants were 31 taxa, the rare and endangered plants which was designated by Korea Forest Service were 21 taxa, the taxa that is more than the t비rd degree among the floristic regional indicator plants which was designated by Korean Ministry of Environment were 40 taxa, and naturalized alien plants to Korea were 27 taxa respectively. Among 1,117 taxa which were not found in this study but recorded in 22 previous literatures, the number of Korean endemic plants were 45 taxa, the rare and endangered plants which was designated by Korea Forest Service were 45 taxa, the taxa that is more than the third degree among the floristic regional indicator plants which was designated by Ministry of Environment were 121 taxa, and naturalized alien plants to Korea were 31 taxa. It can be inferred that the vegetation of Chirisan National Park was changing by some factors and valuable plant resources were tend to diminishing by such as human interference and developments.

Korean Journal of Plant Taxonomy, volume 37, issue 2, 2007, Pages 197~202
Saussurea nipponica subsp. higomontana was recorded first from Mt. Mudeung-san, Gwangju-si, Korea. We named the plant Mu-deung-chui. It had been considered as an endemic plant to Japan. S. nipponica sensu lato is the one of the most famous polymorphic species which consists of 7 infraspecific taxa (subspecies) isolating geographically. Among them, S. nipponica subsp. higomontana is distributed on high mountain regions of Kyushu and Shikoku.

Uchiyama, Tomijiro visited the Korean peninsula including Busan, Incheon, Nampo, Pyongyang, Seoul, Mt. Geumgang of Gangwon-do, and Jeju-do twice for his plant collections in 1900 and 1902, respectively. During his plant explorations, Uchiyama collected numerous specimens which were investigated and studied by T. Nakai (Flora Koreana I and II and other publications) and H. Leveille later. Unfortunately all collection sites were simply described by Nakai in Romanized characters, so that it is difficult to pinpoint those sites using the current or the old Korean map. From this study, many locality names were reviewed based on his own plant specimens at TI and literatures, and those were listed as the order of his collection dates. Based on specimens deposited at TI, only ca. 200 specimens were confirmed, although 1,674 specimens were listed by Nakai. Among his collections, 2/3 of his collections were conducted in 1902 and among them 41 specimens were cited as type collections by Nakai.
