For the purpose of developing Korean Herbalogy with the plants of Urticaceae which grow wild and is planted in Korea, the these and writings on herbalogy, from literature of successive generations, have been thoroughly investigative and the results obtained were as follows: 1. There were totaled 11 genera and 44 species in Korea and among them medecinal plants are 9 genera, 19 species, some 43% in total but the number of species may be added because of similar plants. 2. According to the oriental name which can be used for medical purpose, the medicinal plants beloning to the Urticaceae were classified as Herba 10, Radix 8, Folium 3, Cortex 1, Flos 1, Rhizoma 1. Thus it was noticed that Herba was the main kind. 3. According to sum of 44 species in Urticaceae they were classified into Boehemeria genera 18, Urtica genera 9, Pliea genera 5, Elastosma genera 3, Parietaria genera 2, Pellionia genera 2, Achudemia 1, Debregeasia genera 1, Girardinia genera 1, Laportea genera 1, Nanocnide genera 1 etc. Thus it was noticed that Boehemeria genera was the main kind, some 41% in total. 4. According to nature and flavour of medicinal plants, they were classified into cold, cool; 6 each, wormth, heat; 4 each, balance 3. Thus it was noticed that cold and cool is the main in nature and flavour of medicinal plants. 5. According to the Properties and Principal Curative action, they were classified into, clearing up heat and toxin 9, drugs for urination an removing abscess 7, drugs for circulating blood and hemostasis 7, drugs for expelling wind 5, drugs for comporting embryo 4, 6. Comparing to whole medicinal plants 44 kinds, toxic durgs include minor toxin were 2 kinds, 5% of the whole. Thus toxic durgs were rare. From this result, It was revealed that the plants for medical purpose in Urticaceae was 43% kinds of the whole, in which Herba was mostly abundunt, toxic plants were so rare that it will be used for clinical treatments more easily. It is considered that many clinical experiments and approaches must be continued to use widely.

This study was carried out to clarify the distribution of vascular plants and their usefulness in Geommasan of Gyeongbuk (1,017m, $36^{\circ}\;42^{'}\;30.0^{"}{\sim}36^{\circ}\;45^{'}\; 30.1^{"}N,\;129^{\circ}\;12^{'}\;30.0^{"}{\sim}129^{\circ}\;18^{'}\; 00.0^{"}E$). The vascular plants collected 11 times (from April 2004 to October 2006) were consisted of total 513 taxa; 91 families, 318 genera, 424 species, 3 subspecies, 73 varieties and 13 forms. Among them, edible, medicinal, industrial, ornamental and unknown of usefulness plants were 243 taxa, 307 taxa, 122 taxa, 85 taxa, 77 taxa, respectively. Korean endemic plants of this area were 11 taxa, and Law-protected plants by Ministry of Environment were 4 taxa, The naturalized plants were 21 taxa, therefore naturalized ratio was 4.1%, and Urban index 7.5%.

This study was carried out to clarify the distribution of vascular plants and their usefulness in Irwolsan of Gyeongbuk $(1218.5m,\;36^{\circ}\;45'\;00'\~36^{\circ}\;50'\;10'\;N,129^{\circ}\;02'\;50'\~129^{\circ}\;09'\;00'E)$. The vascular plants collected 16 times (from May, 2002, to May, 2003) were consisted of total 740 taxa; 105 families, 381 genera, 618 species, 6 subspecies, 104 varieties and 12 forms. Among them, edible, medicinal, industrial, ornamental and unknown of usefulness plants were 315 taxa, 428 taxa, 100 taxa, 84 taxa, 201 taxa, respectively. Korean endemic plants of this area were 22 taxa, and Law-protected plants by Ministry of Environment were 6 taxa. The naturalized plants were 27 taxa, therefore naturalized ratio was $3.6\%$, and Urban index $9.7\%$.

This study was carried out to investigate the flora of Manisan (Ganghwa-gun) from April of 2017 to August of 2018. The vascular plants identified during the 12 round field surveys were a to total of 508 taxa: 107 families, 306 genera, 456 species, 7 subspecies, 43 varieties, 1 form, and 2 hybrids. The largest families were as follows; Asteraceae (66 taxa), Poaceae (59 taxa), Fabaceae (25 taxa), Cyperaceae (25 taxa), Rosaceae (22 taxa), Liliaceae (20 taxa), Polygonaceae (17 taxa), Lamiaceae (14 taxa), Ranunculaceae (13 taxa), and Caryophyllaceae (13 taxa). Among these plants, 169 taxa were recoeded for the first time from this region.

Chung, C. erythrobasis H. $L{\acute{e}}v$. & Vaniot, Hemerocallis hakuunensis Nakai, and Lycoris flavescens M. Y. Kim & S. T. Lee were found in this region. The vascular plants on the red list according to IUCN evaluation basis were found to be two taxa: Near Threatened (NT) species of Wikstroemia trichotoma (Thunb.) Makino, and Not Evaluate (NE) species of Tylophora floribunda Miq., respectively. The floristic regional indicator plants found in this area were 26 taxa comprising three taxa of degree IV, four taxa of degree III, seven taxa of degree II, and 12 taxa of degree I.

The performance and characteristics of nutrient removal in wetlands influenced by plant type. We tested a floating plant, Eichhornia crassipes, and a submerged plant, Ceratophyllum demersum, under the same environmental conditions to understand the differences in nutrient uptake by these different plant forms. The total nitrogen and phosphorus in the water decreased in the following order: Water Only < Water + Soil < Floating Plants ${\approx}$ Submerged Plants and Water Only < Water+Soil < Floating Plants < Submerged Plants. Nitrogen and phosphorous concentrations increased in both plants; however, the phosphorous concentration was greater in C. demersum than E. crassipes. The submerged plant exhibited higher phosphorus uptake per unit biomass than the floating plant, but nitrogen uptake did not differ significantly. These results suggest that the presence of soil influences nitrogen and phosphorus removal from water, and that wetland plants play an important role in the assimilation and precipitation of phosphorus. Understanding the differences in contaminant removal performance and characteristics of various plant forms can help in the selection of diverse plants for constructed wetlands to improve water quality and provide ecosystem services such as wildlife habitat and landscape enhancement.
