1876 J. Harley Royle's Man. Materia Med. (ed. 6) 371 Narrow leaves, with a long slit sheath and stipules adherent, forming a membranous ligula.

1882 S. H. Vines tr. J. von Sachs Text-bk. Bot. (ed. 2) 392 Lycopodiaceæ... The leaves have no ligula.

b. Entomology (a) The ‘tongue’ of Crustaceans, Arachnids, and Insects, being a horny, membranous, or fleshy anterior part of the labium. (b) A tongue-like process on the elytra of certain aquatic beetles ( Cent. Dict.).
