Common wheat
Triticum aestivum
The wheat plant has long, slender leaves, stems that are hollow in most types of wheat plants, and heads that have many kinds of flowers, from 20 to 100. The flowers are grouped together in spikelets. Each spikelet has two to six flowers. In most spikelets, two or three of the flowers become fertilized, and this makes them produce the grains used for food.
