The results of the researches on the ecological and morphological characters of Coptis Japonica in Fukui Prefecture are as follows. 1) There are two kinds of Coptis Japonica in Fukui Prefecture; Coptis Japonica M. var J. (Huth) Satahe and C. J. M. var. dissecta (Yatabe) Nakai. Generaly speaking, the former is in Reihoku area and the latter in the moutain area of Reihoku and Reinan. 2) The color of rhizoma is bright yellow and plagiotropy. It brings forth sympodial branching. The position of branching is closely connected with amount of production of C. J. When branching is made near the surface of the earth, the plant is short and poor in growth but in case that branching is made deep in the soil, it comes to be long and stout, so it will give much harvest. 3) The wild kind of C. J. is stiff in leaves and remains green under snow and the original part of branches is made near the surface. The cultivated one is weak against frost. The part above the soil is mostly withered and it tends to make the original part of branches. The wild kinds which grow in the moutain area make branches deep under the soil, because they are destroyed by frost and frost columns. The cultivated kind of the mountain has more distinct tendency mentioned above. 4) Vessel part and sieve tubes come to be woody but phloem and cortex are comparatively thick and berbelin is accumulated in these part. The rate of it seems to be different with the condition of types. climate, soil and cultivation.
