Abstract

We investigated the flora of Ibamsan Mt. and Baekamsan Mt., and discuss here important vascular plants found on these mountains. We created a plant list using voucher specimens collected from Ibamsan Mt. and Baekamsan deposited at CNU. There are 769 taxa in Ibamsan Mt. and Baekamsan Mt., consisting of 116 families, 403 genera, 687 species, 16 subspecies, 58 varieties, and 8 forms. Twenty-four endemic plants of Korea were found, including Coreanomecon hylomeconoides Nakai and Eranthis byunsanensis B. Y. Sun. There are 15 rare plants on Ibamsan Mt. and Baekamsan as designated by the Korea Forest Service, including Iris koreana Nakai and Chamaegastrodia shikokiana Makino & F. Maek., as well as 14 red-list plants as designated by the Ministry of the Environment, including Lycoris chinensis var. sinuolata K. Tae & S. C. Ko ex K. Tae & S. C. Ko and Cymbidium macrorhizon Lindl. In total, there are 133 taxa of floristic regional indicator plants, including four level V taxa, such as Iris koreana Nakai; ten level IV taxa, such as Lindera sericea (Siebold & Zucc.) Blume; 28 level III taxa, such as Botrychium japonicum (Prantl) Underw.; 22 level II taxa, including Hylomecon vernalis Maxim.; and 69 level I taxa, including Dryopteris erythrosora (D. C. Eaton) Kuntze. There are 37 invasive plants, including Rumex acetosella L. and Symphyotrichum pilosum (Willd.) G. L. Nesom.

전라남도 장성군과 전라북도 정읍시, 순창군에 위치한 입암산과 백암산의 관속식물상을 조사하고 분포가 확인된 주요식물에 대해 논의하였다. 1990년 이후 채집되어 전남대 생물학과 표본실(CNU)에 수장된 표본에 근거하여 관속식물목록을 작성하였다. 입암산과 백암산에서는 116과 403속 687종 16아종 58변종 8품종의 총 769분류군이 조사되었다. 한국특산식물로는 매미꽃, 변산바람꽃 등 총 24분류군이었으며, 산림청 지정 희귀식물로는 애기천마, 노랑붓꽃 등 15분류군이 확인되었다. 환경부 지정 멸종위기II급 식물인 진노랑상사화, 대흥란, 노랑붓꽃을 포함하여 14종의 적색목록 식물이 확인되었으며, 이 중에는 멸종위기(endangered species, EN) 범주의 진노랑상사화, 대흥란, 애기천마와 취약(vulnerable, VU) 범주의 백양꽃, 노랑붓꽃, 꼬마은난초, 꼬리말발도리가 있다. 환경부지정 식물구계학적 특정식물종으로는 V등급종인 노랑붓꽃 등 4분류군, IV등급종인 털조장나무 등 9분류군, III등급종인 산꽃고사리삼 등 28분류군, II등급종인 피나물 등 22분류군, I등급종인 홍지네고사리 등 69분류군이 확인되었다. 귀화식물로는 생태계교란식물인 애기수영과 미국쑥부쟁이를 포함하여 총 14과 35속 37분류군이 분포하고 있는 것으로 조사되었다.
