본 연구는 불명산(완주군)지역에 대하여 2015년 4월부터 2016년 10월까지 20차례에 걸쳐 관속식물 분포를 조사하였다. 조사지역의 관속식물은 100과 290속 382종 4아종 38변종 9품종 총 433분류군이 확인되었다. 식재종을 제외한 주요 식물로 한국특산식물 5분류군, 산림청지정 희귀식물 중 취약종이 1분류군, 약관심종이 3분류군이 확인되었다. 환경부 지정 식물구계학적 특정 중 IV 등급종 1분류군, III 등급종 10분류군, II 등급종 3분류군, I등급종 19분류군이 확인되었다. 본 조사지역에서 확인된 외래 및 귀화식물은 돼지풀, 미국쑥부쟁이 등을 포함한 28분류군으로 조사지역 관속식물의 6.5%에 해당한다.

The study aims are to examine the characteristics of artificial and natural hybrids between Viola albida var. albida (= albida, from below) and V. albida var. chaerophylloides (= chaerophylloides, from below), and to confirm if hybrids could be fertile and make populations in their native habitats. The 1st filial (= F₁, from below) leaf shape produced by artificial crossing between albida and chaerophylloides was the same as that of V. albida var. takahashii (= takahashii, from below), and F₁ bore also both chasmogamous and cleistogamous flowers. F₁ seed number was 9.6 per cleistogamous pods, which was remarkably less than the average of 38.2 for albida and chaerophylloides, but the germination rate was all similar. The leaf type of self-crossed 2nd offsprings (= F₂, from below) showed all leaf types found in the Viola albida complex, but the ratio of chaerophylloides leaf type was relatively low. Individuals whose F₂ leaf type was restored to albida produced an average of 31.4 seeds per capsule, meaning that fertility was restored. On the other hand, individuals of F₂ takahashii leaf type come to fruition a low average of 10.4 seeds per capsule, which is similar to that of takahashii. The results of crossbreeding experiment, where is their native habitats, were similar to that of laboratory. Both albida and chaerophylloids in Mt. Bulmyeong distribute extensively, but takahashii make a small population only in places where albida and chaerophylloides grow together. Summarizing the above results is suggesting that the speciation of takahashii was done by hybrid between albida and chaerophylloides, and these have been maintained with relatively small population by cleistogamous capsules.
