Variations of P. sativum include:
Pisum sativum var. macrocarpon is commonly known as the snow pea
Pisum sativum var. macrocarpon ser. cv. is known as the sugar or snap pea
Both of these are eaten whole before the pod reaches maturity and are hence also known as mange-tout, French for "eat all". The snow pea pod is eaten flat, while in sugar/snap peas, the pod becomes cylindrical but is eaten while still crisp, before the seeds inside develop.
