- Teosinte plants are branched and produce many ears
- In teosinte, the leaves along the lateral branches are fully formed and composed of two parts —the sheath that clasps the stem and a well-developed blade that extends away from the stem.
- Teosinte ear possesses about 5 to 12 kernels, each sealed tightly in a stony casing (fruitcase).
- Teosinte kernels can survive the digestive tracts of birds and animals (Wilkes, 1967).
- At maturity, the teosinte ear disarticulates and individual fruitcases become the dispersal units.
- Teosinte cupule is formed from an invaginated rachis segment (internode) and a glume (modified bract) that covers over the kernel sitting in the cupuleIn teosinte, the cupulate fruitcases are borne in two ranks on opposite sides of the longitudinal axis of the ear.
- Each cupulate fruitcase holds a single-spikelet (kernel-bearing structure). Early in teosinte ear development, there are two spikelet primordia on each rachis segment; however, one is aborted early.
- In teosinte plants, each primary lateral branch is elongate and bears a tassel at its tip.
- In teosinte, there are secondary (and higher-order) lateral branches that are terminated by ears, each ear surrounded by a single husk.
- Terminal position of primary branch bears a tassel
