Eophyll
|
The first true leaf of a seedling; i.e., the first leaf to appear after the cotyledon(s). |
|
|
Eophyll
|
The first leaves of a seedling, other than cotyledons, which may or may not be similar to adult leaves in form and position. |
|
|
Ephemeral
|
Lasting a short time; for example, a spring emphemeral in temperate regions that flowers and sets fruits before the canopy trees leaf out or a tree such as species of Tabebuia that flower for only a few days, thus the flowers are ephemeral. Same as evanescent. |
|
|
Epi-
|
A prefix meaning “upon.” |
|
|
Epicalyx
|
A whorl of bracts on the pedicel, similar to sepals, and inserted below the calyx; most commonly found in species of Malvaceae.. |
|
|
Epicarp
|
Same as exocarp. |
|
|
Epichile
|
In the Orchidaceae, the apical portion of a complex lip. |
|
|
Epicortical roots
|
In some Eremolepidaceae and Loranthaceae, roots that develop from the cortex of the stem to form secondary points of attachment to the host. |
|
|
Epicotyl
|
That part of the main axis of an embryo or the young stem of a seedling located above the point of attachment of the cotyledons. The epicotyl gives rise to the leaves, the first of which are called eophylls. |

|
|
Epidermal cells
|
Referring to the outermost cells of the adaxial and abaxial leaf blade surfaces which are covered by cuticle. Subsidiary cells surround the stomates and are distinguished from normal epidermal cells in their size, shape, or orientation. A stomatal type in which the cells surrounding the guard cells are not differentiated from the epidermal cells is called the anomocytic type. |

|
Epidermis
|
The outer layer of cells of a plant. |
|
|
Epífita
|
Se aplica a una planta que crece sobre otra planta durante todo su ciclo de vida, sin parasitarla. Las epífitas poseen raíces aéreas y utilizan a la planta hospedera sólo para obtener un soporte donde desarrollarse, sin tomar agua ni alimento del hospedero (e.g. Tillandsia [Bromeliaceae], Oncidium [Orchidaceae]). |
|
|
Epigeal germination
|
Referring to a type of seed germination in which the cotyledons are held at or above the ground. Compare with hypogeal. |
|
|
Epigeous
|
Referring to the above-ground parts of a plant. |
|
|
Epigynous ovary
|
Referring to a flower in which all or some of the floral parts (i.e., the sepals, petals, and stamens) arise from the summit of the ovary; e.g., species of Asteraceae and Rubiaceae. |
|
|
Epilithic
|
Growing on rocks. Same as epipetric. |
|
|
Epilítica
|
Se refiere a una planta que crece sobre rocas. Igual a litófita |
|
|
Epipeltate anther
|
An anther with the filament attached above the base and with the part of the anther that is prolonged downward facing toward the center of the flower; e.g., in the Dracaenaceae. |
|
|
Epipétala, epipétalo
|
Se refiere a estructuras, usualmente estambres, que están insertos de manera opuesta o de frente a los pétalos |
|
|
Epipetric
|
Growing on rocks. Same as epilithic |
|
|
Epiphyllous inflorescence
|
Inflorescences from the adaxial surfaces of the petiole (e.g., Dichapetalaceae) or the blade (e.g., Phllonomaceae). |
|
|
Epiphyte
|
Referring to a plant that grows on another plant for its entire life cycle. An epiphyte often possesses aerial roots, uses the host plant only for support, and does not obtain food or water from the host, e.g., Tillandsia and many other bromeliads, the majority of the species of Araceae in tropical forests, and most of the orchids in tropical forests. |
|
|
Episépala, episépalo
|
Se refiere a estructuras, usualmente estambres, que están insertos de manera opuesta o de frente a los sépalos |
