The species was discovered in Turkey by botanists Nigel Maxted and David John Goyder and was first described in 1988.

[5] The leaves are pinnate with two leaflets and a terminal tendril that curls and intertwines itself to nearby plants and structures, this allows L. belinensis to hook onto things for support.

[6] The flowers are bicoloured possessing a yellow keel and a standard hosting striking orange and red veins.

[4] It naturally grows on rocky, limestone hillsides in temperate grassland and shrubland at elevations of 560 metres above sea level.

[10] It has also been known to grow in manmade habitats such as graveyards,[10] the sides of roads, railway tracks and margins between arable land.

[11] Lathyrus belinensis is threatened due it its entire wild population being found in only one area.

[14] Breeders are continuing to backcross their lines in hopes of producing a yellow sweet pea.

These hybrids proved to be resistant to the fungus Erysiphe pisi, which causes powdery mildew in sweet pea plants.
