Pteridophyte Flora of Seopseom, Jeju Island
Abstract
This present study found that there were 46 taxa of pteridophyte in the Seopseom, Jeju Island including eight families, 23 genuses, 45 species, and one variety. The findings indicated that there are four families, five genuses and ten species which have not been researched in the previous literature. These newly found ferneries are as followed Dryopteris caudipinna, Cyrtomium devexiscapulae, Dicranopteris pedatum, Selaginella involvens, Deparia petersenii, Colysis wrightii, Dryopteris bissetiana, Dryopteris sacrosancta, Dryteris erythrosora for. viridisora, Dryopteris nipponensis.
These results found in Seopseom area provide evidence that current studies to ferneries are actively being researched. In 2003, Lee, et al. named Dryopteris caudipinna after their first finding and Lee, et al. also found unspecified fern, Deparia petersenii, in the study of Donneko valley, which contributed to finding a species to an existing research. Some of these findings may not completely be new because it was assumed that the seven species, including, Dicranopteris pedatum, Cyrtomium devexiscapulae, Dryopteris nipponensis, Selaginella involvens, Colysis wrightii, Dryopteris bissetiana, Dryopteris sacrosancta, had been inhabited prior to this present study.
Seopseom has a distinctive character, which is a base of a unique Korean native orange, Citrus tachibana, which has the smallest leaves among native oranges. Seopseom provides comfortable climate for ferneries because the habitation of ferneries in the upper area of Seopseom provides an adequate level of shadow that results in comfortable shelter for Castanopsis sieboldii, Daphniphyllum teijsmanni, and Elaeocarpus sylvestris var. ellipticusn.




As seen in Table 4, Seopseom has 46 species, including, a lady fern family Aspidiaceae (39.1%), Polypodiaceae(17.4%), Aspleniaceae(8.7%), Dennstaedtiaceae, Pteridaceae, and Woodsiaceae 6.5%, respectively and Selaginellaceae(4.3%), Psilotaceae, Schizaeaceae, Gleicheniaceae, Lindsaeaceae, and Parkeriaceae 2.2%, accordingly
In particular, Seopseom receives academic attentions in that it is the northest habitual area for Asplenium antiquum, Aspleniaceae family and its uniqueness was designated as the 18th of precious natural treasure, in Dec, 3rd, 1962. Asplenium antiquum, ferneries, has been inhabited in Taiwanand Japanareaand this newly found Asplenium antiquum Seopseom is regarded to be restored
The ministry of forestry recently made an announcement that this Asplenium antiquum became extinct, which should be corrected. Therefore, there should be continuous research in terms of Asplenium antiquum through comparison of that of Taiwan and Japan. This present study found that Asplenium antiquum is in a relatively healthy condition. Kang (2006) found that there were three baby population, which is considered as a spore breeding of Asplenium antiquum, inhabited in the cliff below Lemmaphyllum microphyllum and Arachniodes aristata. This baby population is in a good condition and has increased yearly. In April, 2009, it is found that there are 13 baby populations Asplenium antiquum growing under the cliff and leaf mold. It is foreseen that the growth will be continuous with free of interruption and it is suggested that there needs to be continuous research that examines its origin and comparison of the population between foreign countries.
In the meantime, this present study did not find some ferneries, which were found in the study of Samdo Asplenium antiquum autogenesis of Jeju academy reports, in 2006.
Among wild ferneries, Psilotum nudum, Asplenium antiquum, Crypsinus hastatus, Diplazium hachijoense is a rare species. Even though Psilotum nudum and Crypsinus hastatus have some poor living condition, it is considered that they would be able to return to health wild status with free of interruption
Therefore, it is important to note that Seopseom has shown a superior competitive status in geographical botany. It is also suggested that there needs to be continuous research to manage and maintain the ferneries.
