The traits identify the seeds as oval or long ovate, slightly flat, 1.5-2.5 cm long. The diameter is 0.5-1.5cm. The surface is brown to brownish red, slightly shiny, with irregular concave and fine wrinkles; one end is flat, with a round yellow-brown umbilicus, 5-7 mm in diameter and blunt at the other end. Hard, cut-off seed coat is thin and brittle; there are 2 thick cotyledons, orange or brown. The gas is slight, the taste is slightly sweet, bitter, and sputum. It is better to have large and full.

Microscopically confirmed powder characteristics: light brown. One type of epidermal cell is yellowish brown or reddish brown. The side view cells are 1 column, grid-shaped, 34-59 μm long, 10-17 μm wide, wall thickened, non-woody, outer stratum corneum; surface view polygonal, uneven vertical wall thickening. 2 Stone cells are round and polygonal, most of which have protrusions or branches. The branches are apex apex, the cell diameter is 17-34μm, the wall thickness is 3-10μm, the pits and pores are sparse, and the layering is not obvious. 3 stellate cells are aerobic tissue of seed coat, which are irregular stellate branches, with large intercellular spaces, thin walls and no pores. 4 mosaic layer cell yellow-green or light yellow. It has a long strip shape with a length of 17-46 μm and a diameter of 3-8 μm. The wall is thin and micro-woody. It is composed of several cells and is embedded in the irregular direction with its long axis. The 5 cotyledon cells are round or round-like polygonal with a diameter of 22-51 μm, filled with starch granules, and the starch granules retain a rounded mark after melting. Some cells contain yellow-green or yellow-brown oil. 6 starch granules are spherical, oval, with a few tips at one end or at both ends, 3.5-18 μm in diameter, long

To 23μm, the umbilical point is punctiform, trigeminal or crack-like, the layering is not obvious; the compounding is less, the 2-4 division is composed; the semi-complex is less, and the umbilical point is 2-3.
