Pod corn or wild maize is a variety of corn (maize). It is not a wild ancestor of maize but rather a mutant that forms leaves around each kernel.
Pod corn (tunicata Sturt) is not grown commercially, but it is preserved in some localities.
Pod corn forms glumes around each kernel which is caused by a mutation at the Tunicate locus. Because of its bizarre appearance, pod corn has had a religious significance to certain Native American tribes.[which?]

↑More specifically, a gene ordinarily relating only to vegetative portions of the plant, called ZMM19, was apparently duplicated (in pre-Columbian times), leading to expression of the leafy sheath at the plant's inflorescences.Wingen, L.
