2 comparative study on morphology in the light of the form of the materials, hup shows more approximate relationship with gri : they are 50 ~ 70cm high at the period of fructescence ; both are perennials and reproduce themselves by root stock, and especially, hup can also reproduce itself by branch roots and buds growing from stipes when the stems fall againt the ground, and then those buds develop into new bodies ; while gri can reproduce itself not only by vegetative propagation but by seeds. both of hup and gri characterize with bigger leaf blade and with the approximate form of simple leaf, with root stock, and with two - line seeds in one fruit
