American Joint Vetch 品种
(Aeschynomene americana)
Aeschynomene americana is an annual legume forage crop and green manure cover crop. Considered a “subshrub,” A. americana can reach heights of 1-2 m. Pinnately compound leaves are finely textured, with 25-60 leaflets per leaf. Borne on pubescent stems, leaves reach 7.5 cm in length. Flowers appear in clusters and can range in color from yellow-orange, to yellow with contrasting lines, or even pink. Slightly curved pods are segmented. When ripe, these segments break off, with each segment containing a seed.
