The crown is oblate, semi-open and dense. The large branches are spread obliquely, and the small branches are slightly drooping with coarse hairs. The leaves are leathery, 5.8-8.4cm long, 2.2-43.5cm wide, narrow and long, oblong, with acuminate apex, slightly blunt tip, and broadly wedge-shaped base. The upper side is bright green, the midrib is raised with coarse hairs; the lower side is light green, the midrib is slightly raised, glabrous, with 5-6 pairs of lateral veins, both sides are not obvious; the leaf surface is flat, the edges are finely serrated, and the tooth tips are black. The petiole is 0.7-0.8cm long, thin, more curved, with coarse hairs; the flower is terminal, nearly sessile, 6 sepals, yellow-brown, corolla diameter 4-7cm, 6 petals, white, narrow and long, with oblong heart Shape, deep concave at the apex, slightly wider at the base. During the full fruit period, the average fruit yield per mu is 793.5kg, which is equivalent to 65.9kg per mu of oil. The weight of a single fruit is 20g, the seed yield of fresh fruit is 55.0%, the seed yield of dried fruit is 35.5%, the yield of dry seeds is 51.8%, the oil content of dried kernels is 45.0%, and the oil content of fruit is 8.3%. The main fatty acid composition and content are: palmitic acid (C16:0) 7.2%, palmitoleic acid (C16:1) 0.1%, stearic acid (C18:0) 3.4%, oleic acid (C18:l) 84.8%, Oleic acid (C18:2) 3.8%, linolenic acid (C18:3) 0.3%, maleic acid (C20:1) 0.5%.
