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.
The analysis highlights Poaceae and Cyperaceae, Lycopodiopsida and Asteraceae as prominent areas in the source structure around Ligule.
Source areas are shown by the number of related topics found in each part of the analysis. Use smaller areas too: they can reveal specialized angles and content gaps.
Smaller areas are not necessarily less important. They contain fewer connections in this analysis and can be useful for finding specialized angles or coverage gaps.
