Ligule: Poaceae and Cyperaceae, Lycopodiopsida & Asteraceae

A ligule (from Latin: ligula "strap", variant of lingula, from lingua "tongue") is a thin outgrowth at the junction of leaf and leafstalk of many grasses (family Poaceae) and sedges (family Cyperaceae). A ligule is also a strap-shaped extension of the corolla, such as that of a ray floret in plants in the daisy family Asteraceae.
