Weizi, also known as Yunnan spotted seed in "Flora of China" and scattered weizi in "Chinese Materia Medica", is a shrub, 1.5 (-2) meters tall; the tender branches quickly shed tiny soft hairs, and the branches are hairless. The leaves are membranous or papery, elliptic, narrowly elliptic to oblong, 10-15 cm long, 3.5-8 cm wide, gradually tapering to a pointed or tail-like tip at the apex, and wedge-shaped to broadly wedge-shaped at the base. The margins are sparsely serrated or undulating, rarely nearly entire. The tender leaves are covered with appressed soft hairs on both sides, and only the lower leaf veins of mature leaves are hairy. There are 6-8 lateral veins on each side; the petiole is 2-6 (-10) cm long, hairy, and often has 2 glandular bodies at the apex. The flowers are dioecious, rarely monoecious with separate male and female flowers on the same plant, with the male flower spikes being narrow and conical, with many flowers, up to 18 cm long; the male flowers are white, 2-3 mm in diameter when blooming, with a flower stalk 1-4 mm long; there are 5 nearly circular, hairless sepals, 10-13 stamens, and separate glands. The female flower spikes are shorter, sometimes with only a few flowers; the flower stalks are slightly thicker; the lanceolate sepals are sparsely hairy, and slightly enlarge or hardly enlarge after flowering; there is a ring-shaped disc; the ovary is hairless, with 3 two-cleft stigmas. The capsule is nearly flattened and spherical, 8-10 mm in diameter; the seeds are elliptical, about 5 mm long, with pale brown markings. The flowering period is from August to September.
