- n. Plural form of ligule.
Sorry, no etymologies found.
However, African rice has diminutive ligules (small, thin membranes found at the base of the leaf where it joins the stem).
The variety multiflorus has several forms; the commonest form is double, the disk being filled with ligules much shorter than those of the ray flowers, after the form of many daisy-like composites.
It has ray-florets, the ligules of which have their margins grown together so as to form tubes, with the outer surface corresponding to the pale under-surface of the corolla.
Erect branch; 2 and 3. bits of leaves with ligules; 4 and 5. spikelets; 6. ovary and lodicules.]
