Explanation:
A small spike, especially one that is part of the characteristic inflorescence of grasses and sedges.
A grass spikelet consists of one or more florets (reduced flowers).
Each floret contains a pistil and stamens and is enclosed by two bracts, the lemma and the palea.
Anemophily or wind pollination is a form of pollination whereby pollen is distributed by wind.
Almost all gymnosperms are anemophilous, as are many plants in the order Poales, including grasses, sedges and rushes.
