For shrubs whose height is usually less than 1 m, the thorns on branches are1-3cm long, and those on flower branches are less than 5mm long. Simple leaves, elliptic leaves, sparsely obovate-elliptic, usually 2-4 cm long and 1- 1.5 cm wide, the smaller ones are less than 1 cm long and about 4 mm wide, with round or obtuse top, sparse and short tip, short tip at the base, full edge and slightly convex midvein on the surface of leaves; Petiole length 1-3(-5) mm. Single flower axillary, usually located between petiole and thorn; Calyx cup-shaped, lobes triangular, 5-4(-3) lobed, light green; Petals are white, 3-4(-5) mm long, ovate, pointed and spreading; Stamens are 2-3 times as large as petals. Filaments are tubular, few are in pairs, white, anthers are yellowish, disk is short, style is short, and stigma is not thickened. The fruit is round or oval, with a transverse diameter of 6-8 mm and a slightly rounded top with short convex columns (stigma and style). When it matures, the peel is orange-red, with a thickness of 0.5- 1 mm, 3-4 petals, light or slightly bitter taste, sour pulp and 2-4 seeds; Seeds broadly ovoid or oblate, smooth and without edges; The tip is sharp or blunt, cotyledons and embryos are green, and there are many embryos (up to 8).
