| Ligule | Ligules are strap-like structures that can arise from different structures; for example, the ligule of a species of Bromeliaceae arises from petals; whereas that of a grass arises at the juncture of the blade sheath and the leaf blade and the ligule of a flower of Lecythidaceae arises from fusion of stamens. |  |
| Ligule coiled | Referring to a ligule of Lecythidaceae that coils inward one or more times. In species with coiled ligules, the coiled part with the vestigial stamens is called the androecial hood. Species of Eschweilera and Couratari are the only species that have coiled ligules and they are the only species that have nectaries hypothesized to be derived from vestigial stamens. |  |
| Ligule not coiled | Referring to a ligule of Lecythidaceae that does not make a full coil inward. On the Osa Peninsula only Lecythis mesophylla is known to have this type of ligule. It does, however, have vestigial stamens that are swept inward but they do not form a complete coils as found in species of Eschweilera and Couratari. In L. mesophylla, the hood is the part of the ligule that possesses vestigial stamens. |  |
