The period from 1946 until his retirement from Department of Forest Resources, Seoul National University was a time of research and professional activity on many fronts for Korean Plant Taxonomy. From 1952 to 1984, he travelled south Korea and collected more than 70,000 specimens. Working out of this project, Dr. Lee developed the SNUA herbarium (Herbarium of The Arboretum of Seoul National University) as the best University herbarium in Korea for the modem floristic work. Dr. Lee's first interest rests on his contributions to our understanding of the twig identification in early 1950. Asian deciduous oak taxa have attracted particular focus to him late 1950 and early 1960. Accordingly Dr. Lee has been one of the specialists on systematic study of Asian oak which is a basis of identification in eastern Asia now. Dr. Lee's contributions concerning rare and endangered plants in Korea provide a tremendous information after a Japanese taxonomist, T. Nakai did in early 1920 to late 1930 in Korea. During his fourteen year career from 1970 to 1984, Dr. Lee spent time to investigate flora of many local and National Park sites. Much of his effort was directed to the voucher specimens for which he worked for the Illustrated Flora of Korea and also served as a field collector. These collections at SNUA enabled us to extend our educational outreach from the local to the national flora research. Although Dr. Lee has been and continues to be the soul of SNUA, collection records about his purpose and aim for each trip are not well documented except date and field studied sites. This lesson enables us to tackle the same issue of balancing quantity and quality with well documented specimens now.

Abies koreansa Wilson grows at the upper part of Mts. Halla, Chiri, Mudung, Kaji and Dokyu. It was at first collected by Father U. Faurie on the May of 1907 from the Mt. Halla, Quelpaert. Cone colour of this species varies from green to black purple and the typical colour of it is violet purple. A form of black purple was named by Hatushima in 1934. Green and reddish brown or reddish purple colours of this species were discovered recently at the Mt. Halla. All these forms can be identified as the following. for. koreana - Abies koreana Wilson in Journ. Arn. Arb. 1, 188(1920) ; Mori, En. 27(1922) ; Uyeki, Timb.

Though it is not easy for those who study dendrology to memorize all the scientific names of trees, the names remaines in their memory can facilitate the understanding of foreign technical books. The scientific name of a tree indicates characteristics of shape, color, and other aspects of the tree and by analyzing the name we can see common element found in other scientific names of trees. It is helpful to those who want to memorize and study the scientific names of trees if they understand their etymology. The preseut study is the seconds report of the investigation which aims at examining the etymology of the scientific names of native and foreign trees growing in Korea and their original names not only at the habitat but in Japan, China, England, Germany, and France. While the first report, which was made known in Theses Vol. 9. (The City College of Seoul 1975), is the examination of the scientific names of trees belonging to Gymnospermae, the present report is that of scientific names of trees belonging to Piperales: 2 families, 2 genera and 2 species; and trees belonging to Salicales: 1 family, 3 genera, 44 species, 16 varieties, and 3 forms. As the etymology of the scientific names of trees is made clear, this study will help those who want memorize the scientific names and study foreign technical books and it is also useful for international interchange of trees. The classification is depended chiefly on Dendrology by Prof. Lee Tchang-bok and "Plant Resources of Korea" shown in Biblography No. 10; the native names of trees on Jumoku Daizusetsu by Dr. Uehara; and etymology on A source-Book of Biological Names and Terms by E.C. Jager. In the column of etymology of the scientific names for genera, species, varieties and forms, Gr. stands for Greek, L. for Latin, NL. for New Latin, and genit. for genitive.

1. The inflorescence of the oak has been evolved through a serial reduction of the panicle as is presented in the figure 1. 2. Perianth lobes though they range from one to twelve in a flower six loves occur more than 50% of tested flowers as is tabulated in the table 1. They have been increased partly by a fusion of flowers and partly by a reversion of the stamen into the perianth lobe. They also have been decreased by a fusion of perianth lobes each other. 3. Stamen numbers in a flower range from one to twenty four, but eight stamens are more common than the others as is shown in the table 1. They have been increased by a fusion of flowers and decreased by a fusion of stamens in a flower as are presented in the figure 4. 4. Floral position in the inflorescence, environmental factors, hybridity, and abnormal nutrition supply seem to accelerate fusion and reduction of the stamen in a flower. 5. Flowers which consist of eight stamens and six perianth lobes occur more common than the others, however, the number of the stamen (Y) and the perianth lobes (X) appear to be correlated as follows (see also fig.5.). Y=1.09X+3.78, r=0.4 for Q. dentate Thumb. (7004 flowers investigated) Y=0.71X+4.18, r=0.48 for Q. mongolica Fischer (7409 flowers investigated) Y=1.03X+2.91, r=0.4 for Q. allena B1. (8662 flowers investigated) Y=0.69X+2.00, r=0.4 for Q. serrata Thumb. (9048 flowers investigated) 6. Morphological similarity of the bracteoles and perianth lobes as illustrated in the fig. 3, phenomena of a fusion of bracteoles and separation of perianth lobes into three groups in a flower, and increasing and decreasing phenomena of the stamen number and perianth lobes in a flower as presented in the figures 3 and 4 support the proposal on the oak flower evolution made by H. Hjelmquist in 1948.

Classification on the group of Salix pseudo-lasiogyne growing in Korea, was conducted using cluster analysis, factor analysis, and principal component analysis. Thirty-six characters(Table 2) of the 5 basis species were measured. The phenograms and ordination plot showing the relationships between the species were made by applying the cluster analysis and principal component analysis. Five important factors, such as leaf blade width, number of right serration, angle of leaf apex, number of flowers in an ament, and the ratio of petiole length to width, were inferred from the rotated factor matrix, and their state values were presented in polygonal diagram. Salix pseduo-lasiogyne and S. babylonica were similarly correlated and linked in one group, S. dependens and S. matsudana for tortuosa were secondarily linked in the other group. S. koreensis appeared as an aliemated species from each of the two groups.

It has intended to identify the members of the Genus Lespedeza in Korea by a chemical colour reaction, and the following five species of the Genus Lespedeza grown in the garden have been used in this experiment. 1. Lespedeza bicolor Turcz 2. Lespedeza bicolor var. melanantha (Nak.) T. Lee 3. Lespedeza cyrtobotrya Miq. 4. Lespedeza japonica var. intermedia Nakai 5. Lespedeza maritima Nakai 6.

The objectives of this report is to evaluate the contribution of forest investments by the forest owners for the developments of private forests in the villages where the forest production, especially, chestnut production is active. The results obtained are as follows : 1) Newly purchased forest lands of 526 hectares, 71 percent, in 741 hectares by 96 farmers were replanted with chestnut trees for chestnut production. 2) As the chestnut production is considered to be the unique source of the early capital return in management of forests, selling and buying of forest lands in the area surveyed are enhanced to reforest the forest land with chestnut seedlings. 3) Most of new farmers being engaged in plantation and production of chestnuts in the forests are employees of private industries and government agencies, and merchants in neighboring towns. 4) All materials and expenses for formation of chestnut orchards are generally supplied by forest land owners. 5) Active buying and selling of newly established chestnut bushes are surely served as the estate in the area, thus, the trading of the bushes of young chestnut seedling also enhances the forest as the estate. 6) The management of forest established with chestnut orchards is a special form for forest investment, it makes possible to encourage imputing of capital to the new form of forests, chestnut orchards, and it could be a good possible model for private forest development as compared with that of government funding.
