This construction is typical of most umbels, sometimes composed of umbellets or umbellules - umbels of umbels.
Traditionally, the main morphological differences for identifying these 11 local-used Chaihu are the characters observed from their original plants: the width of involucel bracts, the shape of leaves, the number of umbellules and the vitta number at the vallecula and commissure of fruits; and the characters from the major morphological features of their dried roots: the shape and texture of roots, straight or detached, the color of root and cut surface, with/without fiber-like petiole residues, rich in xylem fiber or not.
Leaves are four-to-five pinnate, but variable, as is the rest of the plant in the dimensions of all its parts, the compoundness of its leaves, the length of the peduncles, the number of pedicels in the umbellules, and the dimensions of the fruits.
