EPAPPOSE: Having no tuft of bristles, a feature often found on seeds that are scattered by the wind, such as the seeds of a dandelion.
EPICALYX: A calyx-like involucre of bracts below the true calyx, as in the mallow, or of sepals, as in the potentilla.
EPICARP: The outer skin of fruits.
EPICHILIUM: The terminal part of the lip of some orchids. Also epichil or epichile.
EPICOTYLE: The part of a plant embryo or seedling above the cotyledons.
EPICOTYLEDONARY: Pertaining to the epicotyl; situated above the seed leaves (cotyledons).
EPIDERMIS: The outer, protective tissue of a plant. In succulents, this may bear protective features such as thick, fine hair or bloom.
EPIGEAL: 1. A plant that grows above the surface of the soil, as most plants in the garden do. 2. A cotyledon that is forced above the ground in the process of germination, as in beans, morning glories, and others. 3. Cotyledons that appear above ground. Also epigeous, epigean, epigaean, or epigeic.
EPIGENOUS: Growing on the surface of a leaf or other plant organ (i.e. fungi grow on the surface of leaves, such as mildew).
EPIGYNOUS: Referring to the calyx, corolla, and stamens that appear to be growing from the top of a ovary, but are actually fused to it, as in the cranberry.
