Awn

Wild rye ear with awns

In botany, an awn is either a hair- or bristle-like appendage on a larger structure, or in the case of the Asteraceae, a stiff needle-like element of the pappus.

Awns are characteristic of many grasses (Poaceae), where they extend from the lemmas of the florets. They often make up the hairiness or other distinctive appearance of foxtails and the like. Awns may be long (several centimeters) or short, straight or curved, single or multiple per floret. Some genera are named after their awns, such as the three-awns (Aristida).

AWN is also a three letter acronym for a fan site of the popular handheld game series, Advance Wars. The site, *[Advance Wars Net], is a dedicated site where many people come to talk and discuss strategies. It is credited with being the first Advance Wars fan site as it debuted in 2001.
