This is the flower of vetch, which is very common in rural areas.
A perennial herb, 30-100 cm high. The rhizome is prostrate, the stem is soft and slender, ascending or climbing, ribbed, sparsely pubescent. The even-numbered pinnate compound leaves are 7-12 cm long, with well-developed tendrils at the top of the rachis; the stipules are semi-halberd-shaped, with 2-4 lobed teeth; the leaflets are 5-7 pairs, long oval or oblong-lanceolate, and 0 6- long. 3 cm, width 0.4-1.3 cm, apex blunt or truncate, slightly concave, short pointed, rounded base, sparsely pubescent on both sides, denser below. Short raceme, 2-4 (--6) axillary flowers; calyx is bell-shaped, calyx teeth are lanceolate or conical, shorter than the calyx tube; corolla is red or nearly purple to light pink, thin white; flag petals are nearly Violin-shaped, concave apex, wing petals shorter than flag petals, keel petals inwardly curved, the shortest; ovary linear, hairless, ovules 5, ovary stalk short, style and ovary connection nearly 90 degrees. Angle; there is a bunch of yellow beard hairs on the abaxial surface of the stigma. The pods are wide and oblong, nearly rhombus-shaped, and 2.1_ long. 9 cm, width O． 5-0.7 cm, bright black when mature, with beak at the tip, slightly curved. Seeds 5-7, oblate and spherical, with brown spots on the epidermis. The hilum is equivalent to 2/3 of the seed circumference. The flowering period is June and the fruiting period is July-August.
In the ancient Chinese poem "Long Song Huai Plucking Wei", the "Wei" refers to this kind of wild pea.

Feeding Value
Vitch pea stems are soft and have good palatability. Its nutritional content has been approved by the Chinese Academy of Sciences Chengdu Biology Analyzed by research institutes and other units, the results are shown in Table 75-2. The budding stage of vetch appears earlier. At this time, there are few branches, the stems and branches are low, tender and soft. Its nutritional content, crude protein, is as high as 26.9%, and the grass yield is also high at this time. After the beginning of spring, as the temperature rises, the plants begin to grow rapidly. On April 14, they entered the pod-bearing stage. The plants were 83.5cm tall. Although the stems and leaves were still green, the grass yield was high at this time, but the nutritional content was reduced. , crude fiber increased, and crude protein decreased to 18.55%. Judging from the branches of the plant, the number of branches during the fruiting stage during autumn sowing can reach 30-40, while during spring sowing there are only about 20 branches during the fruiting stage. Therefore, the most suitable harvesting period should be during the pod-bearing period, which is about 20 days earlier than that of plants of the same genus. This is promoted in southern rice areas and is very beneficial to alleviating the contradiction between previous and previous crops. Promoting it in dry farming areas in southern my country can still solve the contradiction between harvest and pasture; therefore, vetch is expected to be cultivated into a new green manure variety promoted in southern farmlands. The stems and leaves of vetch are rich in calcium and phosphorus and are used as green forage, silage and hay preparation.
