The leaves are opposite, pinnate, and patterned in alternate phyllotaxy. The flowers are papilionaceous. The pods are longish, like a stocking. The skin of the seed is pale red. Primarily grown in Yunlin, Changhua and Chiayi, this food crop is popularly cooked as fresh food, or used to make cooking oil and processed foods. 2. Vigna angularis (NT$7): Commonly known as red beans, it is an annual, herbaceous plant. The stalk is erective, and covered in trichomes. The cotyledons are opposite; the true leaves, patterned in alternate phyllotaxy, consist of three small leaves in circular, oblong, sword or spear shapes. Its flowers are papilionaceous with corollas, the vexillum of the petals has short teeth. The pods are cylindrical, with a beak-like tip. The seeds are ovate and dark red in color.
