[ ] the original morphology of Artemisia annual herb stinky, high 20-100cm. The plant has a strong smell. A single, vertical. Stems erect, single, slightly robust, the axillary inflorescences order branches, with a purplish red. Leaves alternate; petiole is short or sessile; cauline bottom and middle leaves long elliptic, long 6-12cm, width 2-4cm, two back pectinate pinnately lobed, lobes oblong, serrate, base slightly spreading, semiamplexicaul; upper leaf and bract blade is small, a pectinate pinnately lobed. Capitate and expansion of spherical or nearly spherical, diameter 3-4mm, in the stem top or branch end row have spikes, and then form a dense or narrow panicle; involucral bracts3, broadly elliptic, abaxially glabrous or glandular pubescent, margin broadly membranous, violet Brown or dark brown; inflorescences bulges, hemispherical3-8; female flower, corolla narrowly conical or narrowly tubular flowers of both sexes;15-30 duo, corolla tube, a purplish red, outside glandular dots. Achenes oblong-obovate, vertical lines is less obvious. Flower, fruit7-10.

[ character ]
Character identification stems cylindrical, length 1-5cm, diameter 0.2-1cm hollow or pithy surface green, yellow to pale yellow brown, with a plurality of vertical edges of leaves and inflorescence branches with handle. Leaf curl shrinkage, dark green to brownish green, integrity of the leaf is two to pinnatipartite, small lobes linear-lanceolate. Inflorescence hemispherical in shape, diameter 3-4mm, concentrated into a compound raceme; involucral bracts 3layer, the outer layer is a boat-shaped, membranous wide, margin brown; flowers small, tubular, purple is wide, margin brown; flowers small, tubular, purple red or pale yellow brown. Achenes oblong, ca.1mm, tan. Lightweight, soft. Gas specific, bitter, spicy, slightly cool feeling. The color dark green, leaf, flower, more concentrated flavor is preferred.
Microscopic identification of the transverse section of the stem: round or circular polygonal, with more than 10ridge. The epidermal cells of 1layer of mesothelial cells in layer 1, flat and rectangular, square, or irregular in shape, are arranged in rows, to extend the cut, the lateral and medial cell wall thick, outer cuticle. Cortex is narrow, by Jiang Bi6-10multilayer cell composition, type of rectangular, or irregular, shape, to extend the cut, in the longitudinal edge collenchyma developed. Within the cortex was apparent, as the1class rectangle, polygon or square cell, to extend the cut, visible Casparian dots. Pericycle fiber bundles developed, semi-circular or cap off, intermittent arranged in a ring, each beam comprises more than 100to 200 of a plurality of fibers, wood fibers, some cell small, some cell is slightly big. Vascular collateral type,24-40( - 43) multiple, discontinuous arranged in a ring, the ridge inside multidimensional tube is slightly big, phloem phloem parenchyma cells opening narrow, irregular. Cambium is not obvious. The xylem is wide, catheter size number number to several arranged in10rows, of wood. Wood ray by 1-2 column of parenchyma cells near the pith, a bundle sheath fiber bundles, myeloid round, micro lignified, some myeloid most visible hole of the wall, near the center of medullary cells with thin wall. Center of medullary cavity is larger, tender stem center myeloperoxidase-null little or no.
Characteristics: Yellow powder. Pericycle fiber rare, often into a bundle segment, two, walls slightly thin, flat tip acuminate or slightly obtuse, length 327-1460m, diameter 15-25M. Another kind of fiber wall thickness, occasionally, long 10-844/ m,3-9/ m diameter. The pollen grains were more common, spherical or nearly shape, three lobed circular in polar view, the diameter of 26-28m, germination germination hole 3, channel 3, is slightly thick, surface with spotted texture, is not obvious, the film has a foam protuberance. The catheter is more. Lord willing to stretch pit, red with scalariform, thread, diameter of 8-28~ M. Epidermal stem cells apparent oblong or long grain hammer, cells visible particulate matter, some epidermal cells having pores, as the infinitive bracts tissue fragments, easy to see, pale yellow or purplish red, epidermal cells apparent type rectangular, long grain hammer shape or a long shape triangle. Petal lobes epidermal cells are uncommon, spindle-shaped, class of square shape polygon, wall thickening. Glandular hairs are rare, mainly in involucre apex, base of petals and leaves, leaf trichome involucre and no obvious shank, head by 2-4( - 6) -8cells, glandular head diameter 28-50m, petals at the base of the glandular handle visible,2-6cells, in the two row. A remote hair, occasionally, as the word. Present in the leaf abaxial epidermis, single cell head handle into 5-6cells, asymptotic base cells gradually small, often exist in the Ye Jibao film, leaf lower epidermal anticlinal wall corrugated bend.
