Objectives : For the purpose of developing Korean herbalogy of the plants belonging to Polypodiaceae in Korea, the literatures of the successive generations have been thoroughly investigated to prepare this article. The results of this study are as follows : Methods : The examined herbalogical books and research papers which published at home and abroad. Results : 1. There are totaled to 8 genera and 24 species in Polypodiaceae in Korea and among them medicinal plants are 7 genera, 11 species, some 46% in total. 2. Pyrrosia genus is main kind enough that it has 5 species among 24 species in Polypodiaceae, of which medicinal plants are 3 species. 3. The herb is the main medicinal parts if medicinal plants in the Polypodiaceae, which is used in 9 species. 4. According to nature and flavor of medicinal plants in the Polypodiaceae, they were classified into cool 9 species, and cold 5; sweet taste 10 and bitter taste 8 in the order. 5. According to meridian propism of medicinal plants in the Polypodiaceae, they were classified into bladder meridian 5 species, lung meridian 4 species. 7.The number of toxic species in the Polypodiaceae was examined to be none. Conclusions : There are totaled to 8 genera and 24 species in Polypodiaceae in Korea and among them medicinal plants are 7 genera, 11 species, some 46% in total.

Description of spore morphology of Korean Polypodiaceae has on LM and SEM and key to the genera are provided. Korean Polypodiaceae monad, monolete with bilateral symmetry, bipolar and oblete spore except for Loxogramme grammitoides having trilete spore with radial symmetry. In spore wall structure, exopore showed variable patterns enough to distinguish genera. Perispore was found in all the species examined. The patternof perispore and exospore was most similar in all the species examined except Crypsinus, Pyrrosia hastata ans P. linearifolia. The perispores of Crypsinus, Pyrrosia hastata and P. linearifolia were echinate and gemmate, rugulate, and verrucate respectively. In term of exospore wall sculpturing, Polypodium and Loxogramme showed fossulate, Lepisorus, rugulate with irregular verrucate, Crypsinus ans Coloysis showed psilate or rarely verrucate in the latter, Neocheiropteris ensata showed dense small verrucate, Lemmaphyllum microphyllum showed complex reticulate and Pyrrosia showed verrucate or psilate.

Two phenylpropanoids and one flavan 3-ol were isolated from Lepisorus thunbergianus (Polypodiaceae, fern), which is used as folkmedicine. Phenylpropanoids were identified as caffeic acid and chlorogenic acid, and flavan 3-ol was elucidated as (-)-epicatechin 7-O-${\beta}$-D-glucoside by physico-chemical and spectral evidences (HMQC, NOESY).

Fieldwork in Lao PDR during 2007-2008 resulted in the discovery of 15 unrecorded fern species among the flora of Lao PDR. All have been identified in other countries in southeastern Asia, as well as from other tropical areas. The species are as follows: Asplenicaceae (Asplenium delavayi, A. rockier), Athyriaceae (Anisocampium cuspidatum), Dennstaedtiaceae (Microlepia hookeriana, Pteridium revolutum), Dryopteridaceae (Didymochlaena truncatula, Dryopteris cochleata, Polystichum biaristatum, P. lindsaefolium), Gleicheniaceae (Dicranopteris curranii), Hypodematiaceae (Hypodematium crenatum), Lindsaeaceae (Lindsaea heterophylla), Pteridaceae (Pteris decrescens), Polypodiaceae (Pyrrosia nummularifolia) and Thelypteridaceae (Cyclosorus dentatus).

The Late Quaternary palynoflora from an archaeological site in Piseo-ri, Muan, Korea consists predominately of deciduous broadleaved angiosperms and subordinately of herbs and conifers. Dominant taxa are Polypodiaceae, Taxodiaceae-Cupressaceae-Taxaceae, Alnus, Carpinus, deciduous Quercus, Compositae and Gramineae. The palynoflora dated 43,000-18,000 yr BP, corresponding to the last glacial period, is similar to the modern vegetation of the cool temperate deciduous broadleaved forest in the middle part of the Korean Peninsula. Based on palynofloral composition, three palynozones are recognized. Zone I represents a cool temperate deciduous broadleaved forest, composed of Polypodiaceae, Taxodiaceae-Cupressaceae-Taxaceae, Alnus and D. Quercus, and is characterized by persistent occurrence of warm temperate taxa. Zone II shows drastic decrease in Polypodiaceae, Taxodiaceae-Cupressaceae-Taxaceae, and increase in herbs. This zone reflects a cool temperate deciduous broadleaved forest with scattered open grasslands. Zone III is characterized by dominance in herbs and increase in conifers. The palynofloral composition suggests a cool temperate climate, and variation in occurrences of main taxa indicates that climatic conditions gradually became cold and dry.

The plants medicinal resources of Mt. Wol-chul were investigated 8 times from July, 1988 to July 1990. In orther to analyze the vegetation of Wol-chulmountain area, medical wild plants structure and distribution. Medical wildplants of Wol-chul mourltain consisted of 11'0 familis, 338 species in all. Theresources of important herb drugs were Polypodiaceae, Graminea, Liliaceae ,Polygonaceae, Ranunculaceae, Brassicaceae, Rosaceae, Apiaceae, Labiatae, Com-positae .

The plants medicinal resouces of middle area of Korea were investigated 10 times from May 1, 1993 to November 30. 1994. In order to analyze the vegetation of middle wild plants structure and distribu-tion. Medical wiId plants of middle southern area consisted of 100 familis, 380 specis in all. Theresources of important herb drugs were Polypodiaceae, Graminae, Liliaceae, Polygonaceae,Ranunculaceae, Brassicaceae, Rosaceae, Fabaceae, Apiaceae, Labiatae, Solanaceae, Scrophulariaceae,Campanulaceae, Compositae. The herb drugs were comparatively more than in other mountains in ourcountry.

The Korean folk medicine 'Am Cho' has been used as the folk remedy for diuretic, stomach and liver cancer. The botanical origin of the crude drug has not been studied pharmacognostically. To clarify the botanical origin of 'Am Cho', the comparative morphological and anatomical characteristics have been studied of Lepisorus species growing wild in Korea, i.e. L. annuifrons, L. onoei, L. thunbergianus, L. ussuriensis and 'Am Cho' form Korea. As a result, it was clarified that 'Am Cho' from Korea was derived from Lepisorus onoei.

The Korean crude drug 'Suk Wi' has been used as the folk remedy for diuretic and gonorrhea. The botanical origin of the crude drug has never been studied pharmacognostically. To clarify the botanical origin of Suk Wi, studied on the morphological and anatomical characteristics of Pyrrosia species growing wild in Korea i.e., P. linearifolia, P. lingua, P. petiolosa, P. tricuspis and Suk Wi from Korea on Korean market. As a result, it was made clear that Suk Wi from Korea was derived from Pyrrosia lingua and P. petiolosa.
