English Name: Sweet peas, Vetchlings
Description:
Perennials or annuals, often winding and attaching with Tendrils herbaceous plants. Stipule lanceolate or sagittal. Leaves usually double pinnate, ending with small awn or tendril, rarely reduced and instead developed petiole (filodii). Young leaves are pinnate or parallel veins. Blossoms single or collected together in clusters on long stems. Calyx radially symmetric to almost bilabial; teeth most often equal to each other, rarely above slightly shorter. Corolla yellow, pink, purple, white or variegated. Flag back ovoid or oblong. Shipping, usually blunt. Stamens twin; Staminal tube on the top right cut. The bar at the top fiber, rarely naked. The ovary is on foot or seated. Ovules are numerous, rarely 2 - 3. Beans flattened, rarely almost cylindrical, oblong, bursting is. Seed two or more in number, usually spherical, rarely slightly flattened or angulated.

Lathyrus /ˈlæθɨrəs/[1] is a genus of flowering plant species known as sweet peas and vetchlings. Lathyrus is in the legume family, Fabaceae, and contains approximately 160 species. They are native to temperate areas, with a breakdown of 52 species in Europe, 30 species in North America, 78 in Asia, 24 in tropical East Africa, and 24 in temperate South America.[2] There are annual and perennial species which may be climbing or bushy. This genus has numerous sections, including Orobus, which was once a separate genus.[3]
