Vicia nigricans is a species of vetch known by the common name black vetch. It has a disjunct distribution, its two subspecies divided by thousands of miles in range. The northern subspecies, ssp. gigantea (giant vetch), is native to western North America from Alaska to northern California , where it occurs in coastal and moist inland habitat and disturbed areas. The southern subspecies, ssp. nigricans, occurs in southern South America, in Argentina and Chile .[1]
This vetch is a perennial herb with stout, hollow, and ridged climbing stems that may reach two meters in length. It attaches to objects and other plants by its large branched tendrils for support.[2] The leaves are made up of 9 to 13 pairs of lance-shaped or elongated oval leaflets that may measure up to 4 centimeters in length.[2] The inflorescence is a one-sided raceme of up to 15 or 20 flowers which have pale pink to dark reddish purple or sometimes yellowish to orange corollas. The flowers, each with a calyx about half as long as the corolla, are 1 to 2 centimeters long. They yield fruits which are legume pods measuring up to 4 centimeters long by 1.5 wide. As they dry they turn black.
