Hand.-Mazz., Bái Shù, or Yú Shù. A perennial herb. Rhizomes are hypertrophic, lumps. Stems are 50~80 cm high, the upper part is branched, and the base is lignified. The lower stem has a long stalk, leaves are 3-lobed or pinnate 5-parted, lobes are ovate-lanceolate to lanceolate, 5~8 cm long, 1.5~3 cm wide, the apex is long acuminate, the base is attenuated, the edge has long or short needle-like margins, hairs or appressed spiny-toothed, apex lobes are bigger; petioles on the upper stem gradually turn short, narrowly lanceolate, split or undivided, length is 4~10 cm, width is 1.5~4 cm.
Capitulum (flower head) is solitary and grows on the top of the branch, about 2.5 cm long, width is about 3.5 cm, basal bracts are leafy (leaf-like), 3-5 cm long, pinnate lobes are spinous; phyllary is in 5–8 layers, membraneous, imbricate, outside is slightly puberulose (puberulent), out layer is short, oval (egg-shaped), the apex is blunt, the inner layer is in many lines, multirow (multiple columns), apex is blunt, elongated; many flowers, all are tubular flower (tubiform floret), corolla is prunus (violet red), about 1.5 cm long, 5 stamens, style is thin and long.
Achenes are oblong-elliptic, densely covered with yellowish-white fluff, slightly oblate (flat), about 7.5 mm long; pappus is about 1.3 cm long, pinnate, stained white (dirty white), base connate. Its flowering period is from September to October, the fruiting period is from October to December.
Ecological Environment: Atractylodes macrocephala Koidz., grows in mountainous region, and hilly areas, wild species have almost ceased out. Geographical distribution: This species is mainly distributed in China provinces and cultivated in the middle and lower reaches of the Yangtze River.
Growth characteristics: The plant, Atractylodes macrocephala Koidz. prefers a cool climate, cold tolerance, afraid of high temperature and humidity environment, afraid of aridity. It is tolerant to low temperatures of -10 °C (Celsius, or 14 degrees Fahrenheit), growth is inhibited when the temperature is over 30 °C (Celsius, or 86 degrees Fahrenheit), and grows fast at temperatures 25-30 °C (Celsius, or 77–86 degrees Fahrenheit). The optimal temperature for the growth of rhizome is 26-28 °C (Celsius, or 78.8-82.4 degrees Fahrenheit), and the optimal temperature for seed sprouting is 25-30 °C (Celsius, or 77–86 degrees Fahrenheit). It is appropriate to choose high and dry slopy hillside fields, with deep soil layers, loose and fertile sandy loam with good drainage for cultivation, avoid continuous cropping, and better choose newly reclaimed land for cultivation.

Characters of herbs: The rhizomes are irregular hypertrophic lumps and blocks, their length is 3~13 cm, and 1.5~7 cm in diameter. The surface is sallow (grayish yellow) or taupe brown, has tubercules (nodular protrusions), intermittent vertical wrinkles and grooves, and fibrous root marks, and has residual vegetative stem base and bud marks at the top end. The texture of the herb is firm and hard, not easy to break; The fracture surface is uneven, yellow-white to hazel (pale brown), with brownish-yellow dotted oil chambers scattered, and the fracture surface of oven-dried herbs is keratose, dark color, or has fissurings.
