Lespedeza truncatum is a small shrub feed plant. The root system is developed and the taproot is buried deeply, which can exceed 120cm. Erect or semi-erect, the stem thickness of different varieties is different. The plant height is 0.5 ~1m. There are many leaves, and the leaves are trifoliate and compound leaves, which are distributed throughout the stem and branches. Leaflets are long and narrow, wedge-shaped or linear wedge-shaped, with truncated apex and small spines. Racemes are axillary, pedicels are short, and there are 2 ~ 4 flowers with light yellow or purple flowers. There are two kinds of flowers: closed pollination and open pollination. The former is self-pollination, while the latter is often cross-pollination. The pod is small, obliquely oblong and silky white, so it is also called Lespedeza sericea. The flowering and fruiting period is from August to 65438+ 10.
