[ character ]
Character identification stems and one one cylindrical, length, diameter up to 5mm. Green, surface with vertical edges, visible alternate, branches or leaves the base. The dense pubescence. Hard and brittle, easily broken, section fibrous, central white pulp. Leaves shrivel or broken, intact leaves flat after two to three pinnate deeply lobed, lobes linear, both surfaces pilose. The capitulum is more, hemispherical, diameter 3-6mm, peduncle slender, involucral leaves linear, involucral bracts 2-3 column, a wide white edge diaphragm, abaxially pubescent; torus ovate; edge for the female flowers, the flowers bisexual, were tubular. The Immature Inflorescence visible obovate achenes. Gas aroma, taste bitter.
Microscopic identification of the transverse section of the stem: polygon. The epidermis of a column of cells, hair cells by T, radial, longer. Endodermis Casparian dots evident. Bundle sheath fiber wall thickness of petrified wood. Phloem is wide. Cambium is not obvious. Vascular bundle are arranged in a ring, catheter polygon, 2-12 flocks, arranged in a single row. Wood fiber distribution area, cell wall thickening. Ray single row, the cell cavity with inclusions. Resin canal scattered pith. Spinal cord, peripheral cell wall thickening.
Ye Heng: section on epidermal cell, each of the 1 columns, outer cuticle; red see most T-shaped hair or its residue; on the lower epidermis, stomata, but following skin more. Palisade tissue sponge tissue 1-2 columns of cells, rows of cells. Main veins under the skin with thick horn at. The main vein vascular often 1 beam.
Resin powder in palisade tissue. Features: white powder. Cyclophos phamide non-glandular hairs are more, T-shaped, long 3-5mm, colorless, smooth surface, a thick cell wall. The fiber breaking, bundles or single scattered in 9-36 / m, diameter, wall thick and slightly curved, cavity narrowly, pit rare or missing. The catheter is uncommon, with reticulate vessel, the red thread, scalariform and pitted, diameter of 12-35 ~ M. The crystallization is very much, not a single, shape, size of 23-92 m, insoluble in hydrochloric acid. The majority of thin-walled cells, quadrilateral, polygonal or round, colorless, there are few pit.
