Abstract

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.

한국산 고란초과의 포자 형태를 광학 및 주사현미경으로 관찰하여 기재하고 속검색표를 작성하였다. 포자는 방사상칭의 삼지형인 주걱일엽을 제외하고는 모두 좌우상칭인 단지형이다, perispore는 모든 종에 존재하며 미역고사리속, 일엽초속, 밤일엽속, 주걱일엽속, 창고사리속 및 콩짜개덩굴속은 perispore와 exospore가 서로 유사하지만, 고란초속의 경우는 두터운 perispore에자상 돌기와 두상 돌기가 혼재하여 평활상의 exospore와 차이를 보인다. 석위속의 석위와 애기석위는 perispore와 exospore의 표면무늬가 서로 유사하지만 세뿔석위와 우단일엽은 perispore가 각각 난선상과 유두상 돌기를 가져서 exospore와는 크게 다르다. 그리고 exospore가 추문상의 무늬를 갖는 군은 미역고사리속과 주걱일엽속이며, 일엽초속은 불규칙한 유두상 돌기가 있는 난선상, 고란초속과 창고사리속은 평활상이지만 창고사리속의 경우, 드물게 유두상 돌기도 분포한다. 밤일엽은 미립상 혹은 소형의 유두상 돌기가 밀생하고 콩짜개덩굴은 복잡한 망상무늬를 갖는다. 한편 석위속은 분류군에 따라 유두상 돌기가 있거나 또는 평활상이다.
