Feilong palm blood, also known as Achyranthes bidentata, Achyranthes aspera, and Sanxuedan. The old stems have a thick cork layer and yellow-gray, longitudinally fine cracks and raised pores. The pores on the stems of three to four-year-old branches are round and small, and the stems and leaf axes have many sharp downward-bent hooks. The top of the new branches of the year has short brown or red rust-colored fine hairs, or is densely covered with gray-white short hairs. The leaflets are sessile, with densely visible transparent oil spots when viewed against the light, and have a fragrance similar to citrus leaves when rubbed. They are ovate, obovate, elliptic, or obovate-elliptic, 5-9 cm long and 2-4 cm wide, with a long pointed or acute apex at the top, sometimes slightly concave, finely serrated leaf margins, and numerous slender lateral veins. The flower stalk is very short, with extremely small scale-like bracts at the base, and the flowers are pale yellow-white; the sepals are less than 1 mm long, with short hairs on the edges; the petals are 2-3.5 mm long; the male flowers are in umbel-like conical racemes; the female flowers are in umbel-like conical racemes. The fruit is orange-red or vermilion, 8-10 mm in diameter or slightly larger, with 4-8 longitudinal shallow grooves, which are very obvious when dry; the seeds are 5-6 mm long, about 4 mm thick, with a brown-black seed coat and extremely fine pitting. The flowering period is almost all year round, with most flowering in spring in various places south of the Wuling Mountains, and in summer along both sides of the Yangtze River. The fruiting period is mostly in autumn and winter. Distribution area.
