Among plants known as legumes (beans, peas, alfalfa, clover, etc.) the seeds are contained in a fruit that is itself called a legume, better known as a pod.

i. The flowers that gave rise to such pods were not pollinated.
ii. Pollen tubes did not enter all of the ovules in such pods.
iii. There was apparently not enough endosperm to distribute to all of the ovules in such pods.
iv. The ovules that failed to develop into seeds were derived from sterile floral parts.
v. Fruit can develop, even if all ovules within have not been fertilized.
