Ligule
|
A prolongation of the staminal ring from the abaxial side of a flower (Tsou & Mori, 2007) in zygomorphic-flowered species of Lecythidaceae. |
|
|
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 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 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 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 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 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: 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. |

|
Limen
|
In some Passifloraceae, a ring or a cup-shaped membrane more or less closely surrounding the base of the gynophore. |
|
|
Line of opercular dehiscence
|
A circular sulcus around the summit of the ovary which indicates the place where the operculum will fall from the base of the fruit. |
|
|
Linear
|
Con forma de línea. Se refiere a la forma de una lámina de una hoja, sépalo o pétalo cuando es muy alargada, angosta y cuya relación longitud/ancho es 10:1 o más |
|
|
Linear
|
Referring to a two dimensional shape in which the greatest width extends throughout a middle zone at least one-third the length of the blade (in this zone the margins are more-or-less parallel) and the length to width ratio is 10:1 or more. |
|
|
Linguliform, ligulate
|
Tongue-shaped. |

|
Linnaeus
|
A Swedish botanist, zoologist, and physician who is credited with the system of binomial nomenclature. In 1753, he published Systema Plantarum, a way of naming plants considered to be the starting point of botanical nomenclature. |
|
|
Lip
|
The median petal of Orchidaceae which is usually highly modified and different from the two lateral petals, the lip of orchids often plays a crucial role in the plant's pollination; one of the two divisions of a bilabiate corolla, e.g., in the Lamiaceae. |

Litter Score

0-5 scale of % organic litter present compared to an "ideal" state, and the % of that litter that is from non-native species |

|
Liverwort life cycle
|
Referring to the alternation of generations between the gameophyte (haploid) and sporophyte (diploid) stages of a liverwort. The most conspicuous stage of the life cycle is the gametophyte generation whereas the sportophyte generation is small and inconspicuous. |
