Maize (Zea mays) is a tall, deep-rooted, warm weather annual grass. A single long stalk will develop from seed. Long smooth leaves are attached at the stem nodes. Seed producing shoots originate from the base of the main stem. The female flowers are borne on the corn 'ear', which arises at a leaf axil near the mid-point along the stem. The flower organs, and later the grain kernels, are enclosed in several layers of papery tissue, termed husks. A mass of long styles (silks) protrude from the tip as a mass of silky threads. These strands are actually the stigmas from the flowers and emerge at the same time the pollen from the terminal tassels is shed. The pollen is wind blown and comes in contact with the emerged silk or stigma.
