In the original plant of Arisaematis Rhizomas, the features of external and internal shape of Arisaema amurense var. serratum NAKAI and A. amurense MAXIM. are as follows. 1. In the external shape of original plant, Arisaema amurense var. serratum NAKAI has high stem, an oval-elliptic leaflet and a serrate leaf margin. But A. amurense MAXIM has a relatively low stem, an upside oval leaflet and no serrate leaf margin. 2. On the herbs character of original plant, Arisaema amurense var. serratum NAKAI is small in height and diameter, but A. amurense MAXIM is relatively large in. height and diameter. 3. On the gathered herbs character of original plant, the section of Arisaema amurense var. serratum NAKAI is brightly white, easily spilt and strong scent. But the section of A. amurense MAXIM is thin yellowish brown, not easily spilt and weak scent. Also the grade of gathered herbs, both can be classified by diameter and external scent. 4. In the current herbs character, Korean and Sichuan Province products are irregullar shape and have no scent, Jilin Province products are regular shape. Also, Guangxi Province products are small size and concave in one side, Hebei Province products are irregular size and shape. 5. In internal shape of original plant, epidermal cell of Arisaema amurense var. serratum is very tight. With the except of micro difference in parenchyma cell of cortex, on the whole there are nearly no differences with A. amurense MAXIM. Also, samely in the internal shape, according to collecting sites, epidermis exhibits a lot layer in curving state and secreting duct is developed and vascular bundle and exists between parenchyma cell of cortex. In the future, additional study is needed to distinguish herb and effect between same genus-degree of relatedness.
