Lígula Órgano loriforme; por ejemplo, la lámina de la corola de una flor radial de algunas Asteraceae; la estructura interna en la vaina de las hojas de Cyperaceae, Poaceae y Zingiberaceae; la estructura que se encuentra en los pétalos de algunas Bromeliaceae; la estructura que se encuentra en la corona de algunas Apocynaceae; o la estructura del androceo de las flores zigomorfas de Lecythidaceae
Lígula enrollada Se refiere a la lígula de las Lecythidaceae que está enrollada una hasta varias veces hacia la parte interior. En especies con lígulas enrolladas, la parte enrollada que porta los estambres rudimentarios se denomina la capucha del androceo. Especies de Eschweilera y Couratari son las únicas que poseen lígulas enrolladas y nectarios hipotéticamente derivados de los estambres vestigiales
Lígula no enrollada Se refiere a la lígula de las Lecythidaceae que no está enrollada hacia el interior. En la Península de Osa, este tipo de lígula solamente se conoce en Lecythis mesophylla. Esta especie presenta estambres rudimentarios dirigidos hacia el interior, pero su lígula no se encuentra enrollada hacia el interior, como sucede en las especies de Eschweilera y Couratari. En L. mesophylla, la capucha es la parte de la lígula que porta los estambres rudimentarios. Lígula no enrollada
Ligular sulcus A groove or furrow close to the point where the androecial hood begins, i.e., between the appendix-free ligule and the androecial hood. Ligular sulcus
Ligulate Furnished with a ligule.
Ligulate capitulum (head) Inflorescence of Asteraceae with only ligulate flowers. Ligulate capitulum (head)
Ligulate flower A zygomorphic flower with a straplike corolla found in the Asteraceae tribe Lactuceae. Differring from a ray flower by having five instead of three lobes. Ligulate flower
Ligule A prolongation of the staminal ring from the abaxial side of a flower (Tsou & Mori, 2007) in zygomorphic-flowered species of Lecythidaceae. Ligule
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
Ligule arched The ligule departs from the staminal ring and is curved for its entire length or, in other words the ligule curves downward from the middle to both its attachment to the staminal ring and to its distal end. Ligule arched
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 coiled
Ligule flat A ligule that arches at its departure from the staminal ring and then levels off, in other words the part that is flat is the part that covers the summit of the ovary which also equals the androecial hood. Ligule flat
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. Ligule not coiled
Ligule undulate A liguler that is similar to flat but is undulate along its length. The most important feature of this ligule shape is that the ligule is not undulate for its entire length. Ligule undulate
Ligule: Couroupita nicaraguarensis-Type The androecium is prolonged from one side of the staminal ring into a ligule that is covered with stamens and staminodes without interruption from the staminal ring to the apex of the ligule, i.e., there is no appendage free ligule and there is no well-differentiated hood. There is, however, a progressive increase in staminodes from the staminal ring to the end of the ligule such that all appendages in the staminal ring are stamens and most appendages at the end of the ligule are staminodes. There are no antherless appendages on the ligule. Ligule: Couroupita nicaraguarensis-Type
