By the morphological and anatomical studies of the stem of wangul (C Iwasakii M. and C glomeratus L.) iri Korea, the following results were obtained 1.The stem of C.Iwasakii is longer and thicker than that of C.glomeratus, and there is not much difference in the stem numbcr between the two species. 2. The shape of a transverse section of stems shows variation from an equiangular triangle to an isoseeles triangle, but there is not fcund any difference between C. Iwasakii and C.glomeratus. 3. In a trarnverse section of the stem at its top, middle and base portions, the largest is the mlddle in C.Iwasaikii and the base in C.glomeratus respectively. The transverse section at the top is the smallest in both species. 4. The shape of sclerenchyma in the cortical layer is concave in C.Iwasakii, but convex in C glomeratus, and the parenchymatous cell in the medullary portion of the stem is fcur or five angular in the former, but roundish in the lattef. These anatomical differences will serve to discriminate, between thetwo species.
