Palkokasvikesimyskä

Palkokasvikesimyskä, scientifically known as Lathyrus aphaca, is an annual herbaceous plant belonging to the pea family (Fabaceae). It is characterized by its slender, climbing stems that can reach up to 60 centimeters in length. The leaves are pinnately compound, typically with only one pair of leaflets, and are distinguished by their large, leaf-like stipules that resemble the leaves themselves. These stipules are often a prominent feature of the plant. The flowers are small, pea-like, and typically yellow, appearing singly or in pairs on long stalks. The plant produces small pods containing a few seeds.

Lathyrus aphaca is native to Europe, North Africa, and parts of Asia. It is often found in disturbed habitats such as fields, roadsides, and wastelands, preferring well-drained soils. The plant's climbing habit allows it to scramble over other vegetation, utilizing their support for growth. While it shares the family name with edible peas and beans, Lathyrus aphaca is not considered a food source and is generally regarded as a weed in agricultural settings due to its ability to compete with crops. Its ecological role is primarily as a component of the flora in its native and introduced ranges.
