Main species of Bidens pilosa

Bidens pilosa

The pinnate-leaved Bidens pilosa is named because its leaves are trifoliate or pinnate-shaped. Its stem is nearly cylindrical and slightly quadrangular, with extremely narrow wings on the petiole. The leaves are usually linear or linear-lanceolate with coarse serrations on the edges. The fruit is 3-4.5 mm long and 1.5-2 mm wide, and is an achene. It is often found on roadsides and riverside wetlands. The whole herb can be used as medicine, with detoxifying and anti-inflammatory effects.

This type of Bidens pilosa is different from the Bidens pilosa L. Its leaves are not divided and are needle-shaped, and it is named after its willow-like shape. The edges of its leaves also have sparse serrations, the stem is nearly cylindrical, and the fruit is also achene, narrowly wedge-shaped, four-sided, 5-6.5 mm long, larger than the fruit of Bidens pinnata. Likewise, it can be used as a herbal medicine to detoxify and remove blood stasis.

The stem of Bidens pilosa is obtusely quadrangular, with three-lobed or undivided leaflets at the bottom, pinnate compound leaves in the middle, and elliptical leaflets growing on both sides. The leaflets at the top are elliptical, three-lobed or undivided. The fruit is also an achene, black in color, 7-13 mm long. Its special feature is that it has white ligulate flowers that are 5-8mm long and 3.5-5mm wide. It can also be used as medicine, which is what distinguishes it from the other two types of Bidens pilosa.
