Lathyrus sphaericus Retz.

Lathyrus sphaericus Retz.. Lathyrus sphaericus, commonly known as grass pea and round-seeded vetchling, is a species of annual flowering plant in the legume family (Fabaceae). It typically grows to between 15 and 30 centimetres tall and bears distinctive brick-red flowers. The species is native primarily to Mediterranean and sub-Mediterranean regions, ranging widely from southern Europe and North Africa to Western Asia. It favours dry, nutrient-rich soils and is commonly found in disturbed habitats, including roadsides, vineyards, fields, and pasturelands. Recently rediscovered in Slovakia after a lengthy absence, it is considered critically endangered there, reflecting ongoing changes in its distribution likely influenced by climate warming.
